I often see people post this error message in the forum. So, I decide to make the post. Hope this tutorial will help

Server Error in '/' Application

This collection already contains an address with scheme http.  There can be at most one address per scheme in this collection.
Parameter name: item

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.ArgumentException: This collection already contains an address with scheme http.  There can be at most one address per scheme in this collection.
Parameter name: item

Solution:

The solution, since WCF services hosted in IIS can have only one Base Address was to create a custom service factory to intercept and remove the additional unwanted base addresses that IIS was providing. In my case IIS was providing:

domain.com
www.domain.com
dedicatedserver1234.hostingcompany.com

We are able to customize our .svc file to specif a custom serive factory

We are then able to create our custom factory by inheriting from ServiceHostFactory and overriding as required

    class CustomHostFactory : ServiceHostFactory
    {
        protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
        {
              CustomHost customServiceHost =
                new CustomHost(serviceType, baseAddresses[1]);
            return customServiceHost;
        }
    }

    class CustomHost : ServiceHost
    {
        public CustomHost(Type serviceType, params Uri[] baseAddresses)
            : base(serviceType, baseAddresses)
        { }
        protected override void ApplyConfiguration()
        {
            base.ApplyConfiguration();
        }
    }

In my case I decided to pass through baseAddresses[1] (which was the www. address) but it would probably be wise to specify that address you want to prevent changes by your web host from impacting your code.

This blog posts shows a step-by-step instruction how to integrate the Unity 2.0 dependency injection container in an ASP.NET MVC 3 web application.

Create MVC 3 project and add Unity 2.0

Create a new "ASP.NET MVC 3 Web Application" project in Visual Studio 2010. For simplicity, we will use the project template "Internet Application", which adds some some sample controllers and views to the project.

Download Unity 2.0 here from MSDN and run the setup. By default, the setup will extract all Unity files to C:\Program Files (x86)\Microsoft Unity Application Block 2.0\. Copy all dll files from the subfolder bin into your ASP.NET MVC 3 project. It is recommended to save them in a new subfolder (for example "libs") in your project. In detail, the project should now contain the following the dll files:

- Microsoft.Practices.ServiceLocation.dll
- Microsoft.Practices.Unity.Configuration.dll
- Microsoft.Practices.Unity.dll
- Microsoft.Practices.Unity.Interception.Configuration.dll
- Microsoft.Practices.Unity.Interception.dll

In the Solution Explorer, right click on "References" and click on "Add Reference..." and select these five dll files in the tab "Browse" to reference the libraries in your project

Register MVC 3 DependencyResolver

To use the Unity dependency injection container in the newly created ASP.NET MVC 3 project we first need an adapter class, that implements the interface IDependencyResolver and maps the method calls to a concrete Unity dependency injection container (an instance of IUnityContainer, see this post):

public class UnityDependencyResolver : IDependencyResolver
{
  readonly IUnityContainer _container;
  public UnityDependencyResolver(IUnityContainer container)
  {
    this._container = container;
  }
  public object GetService(Type serviceType)
  {
    try
    {
      return _container.Resolve(serviceType);
    }
    catch
    {
      return null;
    }
  }
  public IEnumerable<object>GetServices(Type serviceType)
  {
    try
    {
      return _container.ResolveAll(serviceType);
    }
    catch
    {
      return new List<object>();
    }
  }
}

In the Global.asax.cs file we will set up a Unity dependency injection container in the Application_Start method and use our little adapter class to register the Unity container as the service locator for the ASP.NET MVC application.

protected void Application_Start()
{
  [...] 

  var container = new UnityContainer();
  container.RegisterType<IMessages, Messages>();
  DependencyResolver.SetResolver(new UnityDependencyResolver(container));
}

In the above code, we also register a type with the container using the RegisterType method (you can find detailed information about configuring the Unity container and in the MSDN library).
In this simplified example, we just register the type IMessages with the concrete implementation Messages. The next section shows how this type is implemented and used.

Resolving dependencies

To test the dependency resolving, we modify the HomeController.cs and add a new property Messages which is annotated with the Dependency attribute and use this property in the Index action:

public class HomeController : Controller { 

  [Dependency]
  public IMessages Messages { get; set; } 

  public ActionResult Index()
  {
    ViewBag.Message = Messages.Welcome;
    return View();
   } 

  [...]
}

Of course, before we can build our ASP.NET application we need to implement the IMessages interface and Messages class:

public interface IMessages
{
  String Welcome { get; }
} 

public class Messages : IMessages
{
  string IMessages.Welcome
  {
    get { return "Hello world from Unity 2.0!"; }
  }
}

After building and starting the application the Unity dependency injection container should resolve the dependency that is defined in the HomeController and the application's start page should say "Hello world from Unity 2.0!".

Microsoft's Visual Studio Live! is a developer's conference that is all about development in the Visual Studio environment. Visual Studio Live! Orlando was held at the Hilton Walt Disney World Resort in November 2010. One of the big announcements from this conference was the launch date for Visual Studio LightSwitch. And what now you can get this visual studio lightswitch hosting at ASPHostPortal.com. This article contains brief information about the benefit and the useful of Visual Studio LightSwitch.

Visual Studio LightSwitch is a rapid development environment that gives technical and somewhat technical people the ability to create lightweight, line-of-business applications. While many developers don't think Visual Studio LightSwitch will be useful for creating applications, I think it can be very beneficial to use in the right circumstances. Here are some reasons why.

Right-sized versus enterprise-ready

In recent years there has been a growing philosophy that everything needs to be enterprise-ready. The prevailing thought is that all solutions need to be scalable, flexible, "anything-able." While that is true for anything that really does need to be enterprise-ready, there are situations where enterprise-ready is too much.

Imagine you are a small startup. You are not focused on enterprise-ready. You are focused on getting through your first year. Alternately, you might be an established organization that is considering getting into a new line of business. Focusing on getting something up and running to let your employees share information in a cost-effective way would ensure that you are not risking valuable resources (that is, capital). In today's economy, capital budgets are limited (and nonexistent in some companies).

The best of both worlds

Traditionally, we have seen tools such as Access, Excel and, more recently, SharePoint, act as a useful starting point for a low-cost prototype. The best thing that can be said of those initial forays in developing line-of-business applications is that usually all of the necessary data points have been identified and there is a working prototype. I find that having a working prototype is immeasurably helpful when starting an enterprise application development effort.

While Access and Excel solutions do provide value when moving to the next level of maturation, Visual Studio LightSwitch can provide even more. Since Visual Studio LightSwitch can connect to Microsoft SQL Server or Oracle databases, the application can utilize either of those databases during the initial development.

Visual Studio LightSwitch also generates an ADO.Net Entity Framework (EF) class structure that can be used in the next iteration of development. Finally, the interface is rendered to a Microsoft Silverlight application.

Recently, I had a customer request a simple application for generating quotes for customers and tracking them in a Web format. Taking this use case, it was decided to give LightSwitch a go. We were able to build a working prototype for the need within four hours—complete with the database tables, class structure and Microsoft Silverlight interface. Normally, in a traditional Web development environment, this would have taken close to 40 hours to get to the same point.

Efficiency versus maturation

Some people point out that if this right-sized application is successful, that it will need to be rebuilt, usually from the ground up. While this is mostly true, it's relevant to restate that having a working prototype does reduce the risk (risk=time+money) in starting a new application.

So, would it be more efficient to build the enterprise-ready version of the application first? The assumption there is that you are going to get the application right the first time or that the application will be used for a period of time to recover its return on investment. But aren't those two very big assumptions? Furthermore, aren't those two very expensive assumptions?

Also, it's relevant to say that enterprise software endeavors are never guaranteed successes. We all know the high rate of failure for traditional development, whether it is done using an agile or waterfall approach. Approximately 50 percent of all features are either never used or rarely used. Why not develop those features inexpensively first and then decide what needs to be in your final application? These are the types of benefits Microsoft's Visual Studio LightSwitch can provide, making it something to consider moving forward.

Action Filters are a great way to handle cross-cutting concerns in ASP.NET MVC such as Logging, ExceptionHandling, etc.  In previous versions of MVC3, action filters have to be explicitly added to each controller. 

MVC3 adds the concept of Global Action Filters which allow you to apply action filters globally without the need for explicit declaration.  In this example, we’ll demonstrate how to add a debug action filter attribute that shows debug information for each view using Global Action Filters.

DebugInfoAttribute.cs

/// <summary>
    /// Displays the elapsed time and environment for each executed action in the HTTP Response Stream.
    /// </summary>
    public class DebugInfoAttribute : ActionFilterAttribute
    {
        readonly Stopwatch _startWatch = new Stopwatch();
        private static string _outputFormat = "<h4>Debug Environment Info</h4><div class=\"debuginfo\"><table><tr><td>Web Server:</td><td>{0}</td></tr><tr><td>Browser:</td><td>{1}</td></tr><tr><td>Controller</td><td>{3}</td></tr><tr><td>Action:</td><td>{4}</td></tr><tr><td>Execution Time(ms):</td><td>{5}</td></tr></table></div>";
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            _startWatch.Start();
        } 

        public override void OnResultExecuted(ResultExecutedContext filterContext)
        {
            _startWatch.Stop();
            var browser = filterContext.HttpContext.Request.Browser;
            filterContext.HttpContext.Response.Write(string.Format(_outputFormat,
                                                                   HttpContext.Current.Request.ServerVariables[
                                                                       "SERVER_NAME"],
                                                                   String.Format("{0} ({1})",browser.Browser,browser.Version),
                                                                       filterContext.RouteData.Values["controller"],???????????????
                                                                       filterContext.RouteData.Values["action"],
                                                                       _startWatch.ElapsedMilliseconds));
        }
    }

This action filter uses the StopWatch object to clock how long the action took to execute, and displays that information in a view.

It’s applied normally by adding the “DebugInfo” attribute to the top of a controller class, as below.

[DebugInfo]
    public class HomeController : Controller

This results in the output seen below on our views:



If we click the “LogOn” link on our default application, we won’t see this information as we haven’t applied this filter to the “Account” controller.  Lets see how we can set an action filter to display gloablly.

Registering Global Action Filters

MVC3 adds a new function into our Global.asax called Register Global Filters.  To apply a filter globally, simply add a new line specifying your action filter as below.

public static void RegisterGlobalFilters(GlobalFilterCollection filters)
        {
            filters.Add(new HandleErrorAttribute());
            filters.Add(new DebugInfoAttribute());
        }

Now, when we click on the “Log On” link, we can see the DebugInfo filter has been automatically applied to the Account controller.

Microsoft's release of ASP.NET MVC 3 offers developers a new and improved framework for building web applications in the Model-View-Controller pattern. As expected, ASP.NET MVC 3 comes with many new features that improve on the ones present in MVC 1 and 2. It can also be installed side-by-side with ASP.NET MVC 2. Before we discuss ASP.NET MVC 3's installation process, let's discuss some of the framework's new features first.

The new Razor view engine comes with plenty of useful features within itself, such as HTML helpers.  It is based on well-known languages such as Visual Basic and C#, so its learning curve is minimal.  The view engine also helps to improve efficiency by cutting down on keystrokes with syntax that is short and to the point.  You can unit test Razor views without having to run an application or launch a web server as well.

ASP.NET MVC 3 also offers support for multiple view engines and implements various controller improvements. The new ViewBag property is one controller improvement that is similar to the ViewData property, but offers a simpler syntax.  Other controller improvements in MVC 3 include some new ActionResult types and global action filters.

The realms of JavaScript and Ajax have drawn some improvements as well.  For example, client-side validation is now enabled by default, and JSON binding support has been integrated.  ASP.NET MVC 3's other highlights include better support for dependency injection, model validation improvements, partial-page output caching, sessionless controller support, and more.

Now that you have a preview of some of the improvements that ASP.NET MVC 3 has to offer, it's time to download and install the framework.

To begin installing ASP.NET MVC 3, visit the following link:

http://www.microsoft.com/web/gallery/install.aspx?appid=MVC3

Before you start the download, there are some system requirements to keep in mind.  For the installer to work, you will need to have administrator privileges on your computer.  You will also need to be using one of the following operating systems:

Windows 7, Windows Vista, Windows Vista SP1, Windows XP SP2+, Windows Server 2008, Windows Server 2008 R2, or Windows Server 2003 SP1+.

Begin the installation by clicking on Install Now.  Depending on which internet browser you are using, you may be asked to either save the installer file or run it.  After you have saved the file and it has downloaded, locate it and double-click to begin the installation using Microsoft's Web Platform Installer.



Once the installer appears, click Install.



A window will appear that displays the different components that will be installed.  Once you have looked over the components, click I Accept.  The installation should now begin.  The process could take a while, so give it some time to complete.



After the installation is completed, a congratulations window will appear.  Click Finish to exit the installation.

4. Select the LightSwitch Application (Visual Basic) template which we will use for this demo and enter a name for the project (in this case I have used lightswitchdemo)





5. Once the application has been created you will be shown an option to either Create a New Table (if the app is being created with an all new database) or Attach to External Database if you need to use LightSwitch as a front-end to an existing database. For this tutorial we will select Create a New Table:



Before we proceed, note the structure of the LightSwitch project from the Solution Explorer in Visual Studio. There are three elements :

- Properties – which is main configuration settings for LightSwitch, such as whether the app will be deployed as as a browser app or a stand-alone desktop app.

- Data Sources – the data tables being used to data storage by the LightSwitch app.

- Screens – the front-end ‘screens’ or pages which the end user will use to interact with the application.

Creating a Data Table in LightSwitch

In this section of the tutorial we will create a table for storing the company’s customer data

1. Click Create new Table from the screen shown above (alternatively you can right-click on Data Sources in the Solution Explorer and select Add Table).

2. Enter the details for each field in the table entry form. In this demo of a customers data tables I have used the fields FirstName, LastName, Email and PhoneNumber. Set the data type for each field, the default type is String, but note the types of EmailAddress and PhoneNumber which have inbuilt validation (as we will see in later tutorials) and should be used whenever possible for these fields. Save the fields by click Control+S or the save icon in the Visual Studio toolbar. For this tutorial I have set all fields to Required, but note that you will often want to uncheck this requirement for some fields to make their input option.



3. Change the table name to Customers by right-clicking on the table (currently named TableItem1) under Data Sources > ApplicationData , and then selecting Rename

Display Customer Data in an Editable Grid

In this final part of the tutorial we will create a simple one screen grid which the user will be able to view, edit and add customers to the LightSwitch application.

1. Right-click on Screens in the Visual Studio Solution Explorer and then select Add Screen…  You will then be shown the below screen which lists out the current screen templates available for creating user interfaces in LightSwitch



2. Select Editable Grid Screen from the Listing, enter EditableCustomerGrid as the Screen Name  (note that you cannot use spaces for the Screen Name) and select Customers for the Screen Data as shown below and then click OK and the screen should be immediately visible user the Screens folder in the Solution Explorer. Note that for a real-world app we would probably be creating several screens for the app such as a dedicated New Data Screen for inputing data, a Search Screen for performing searches and a Details Screen to display the data.



3. The Properties window should be automatically open, but if not just double-click the EditableCustomerGrid icon in the Solution Explorer. The full listing of screen properties as shown below:



4. Change the Display Name from EditableCustomerGrid to Customers (this is the name of the screen that will be shown to the end-user). Then Save the changes

That’s all that is required to create a very simple LightSwitch app.

Testing and Running the LightSwitch Application From Visual Studio

1. Once the application has been created and saved  hit F5 to run it. The application’s main window (see below)is partitioned into three main areas:
Ribbon: This area at the top of the screen gives quick access to common tasks which are performed in the LightSwitch application. The default tasks in the Ribbon are saving the current changes and refreshing the data source.

- Navigation Pane: On the left of the screen the Navigate Pane lists  the apps screens.
- Main Pane: The main active working screen. To change screens click another screen from the Navigation View.



2. Using the grid you can enter customer data. Note that on data types such as Email and Phone Number, the validation is built in.



3. Once you have entered the data, click Save on the Ribbon and the data will be saved to the database.



Publish and Deploy a LightSwitch Application From Visual Studio

The deployment process for a LightSwitch application differs depending on the application type which has been selected for the application. The application can be set from by double-clicking Properties in the Solution Explorer and selecting the Application Type tab.  There are three  application types – Desktop 2 Tier which creates as a simple WPF desktop app, Desktop 3 Tier which creates a WCF app and uses IIS to connect to the data source and Browser Client 3 Tier which creates a browser based Silverlight app:



In this simple demo we are will leave the default, Desktop client 2 tier deployment.

To start the publication process, right-click the main application icon (in this case lightswitchdemo) and select Publish… , the Publish Application Wizard will then be launched:



The first step is to specific the location on the machine to place the application files on the Specify Publishing Preference page. On this page you also need to specify how to create the database, you can either be published directly to an existing database or create a script which can then be executed to create the database manually.



Next, in the Database Configuration specify the connection string for the database (note that the options would be different if you elected to create a database script).



Next, in the Prerequisites you can specify which additional components  to install for running the application



Finally, you are will be able to specify any additional settings such as connections to reporting servers.



That’s it! This is a very simple application without many of the features required for actual business apps. In later tutorials we will dive deeper into features of LightSwitch.

Introduction

When you are using reports, you need to have parameters that narrow down your report for better analysis. You will often see that you need to have more than one parameter, where the second parameter may depend on the first parameter, which many require you to refresh the second parameter depending on the first parameter.

In addition, you may have to have parameters with multiple and/or default values. This article addresses how to create parameters in SQL Server 2005 Reporting Services (SSRS).

Pre-Requests

To understand the article content, you should have a fair knowledge of creating a report in SSRS, as this article does review how to create a report in SSRS in detail. However, I will try to cover as much as possible when it comes to creation of SSRS report. Also, you will need to know how to write basic T-SQL queries joining two or more tables.

Resource wise, you need to have SQL Server 2005 installed with SQL Server Business Intelligence Development Studio. As I am going to use data in the AdventureWorks sample database, it will be easier if you have installed an AdventureWorks database with your version of SQL Server.

Sample Case

Since it is always helpful to the reader to explain things through example, let us assume we want to list out employees depending on their country, state/province and city. Users should have an option of selecting a country. Depending on the selection of country, we need to list state/provinces which belong to the selected country. After selecting a state, we should list all the related cities and the user should have the option of selecting one or more cities from the list. Depending on the selected city or cities, the user should get a final list of employees that fit the criteria.

Implementation

First, you must create a Report Server Project from SQL Server Business Intelligence, then add a report to the project. Next is to create a shared data source that is pointed to the AdventureWorks database. We now need to add a dataset for country. You can add this dataset from the dataset tab by selecting ‘<New Dataset> Option’ from the dataset list box. Then configure the dsCountry dataset as depicted in the below image.



The next task is to assign this dsCountry to a report parameter. Select the ‘Report Parameters’ option from the Report menu.

Below is an image of the screen you should see.



The options in the dialog box above are:

Name – Name of the parameter. When you select a value, that value is stored in this parameter. As this is a variable name, you cannot have special characters (*, ! or spaces, etc.) in this field.

Data Type – Data type of the parameter. Options of this field include: Boolean, Datetime, Integer, Float and String. In this case, we will chose ‘String’ for the country parameter.

Prompt – Prompt is what you see in the report. As this is a label, you can have any characters for the prompt.

The following attributes are as simple as their names indicate. The difference between Hidden and Internal is that hidden variable can be changed from mechanisms and internal variables cannot be changed.

The next step is to assign values for the parameters.

The non-queried option should be used when a parameter has fixed values, such as Yes/No, Male/Female etc. From query option is to fill values from a dataset to parameter. In this example, the dataset is dscountry and we need to fill in two values: value field and label field. The label field is what users will see and the value field is what will be stored in the parameter. In this case, Name is the label field while CountryRegionCode is the value field. For example, if the user selects the United Status, US will be stored in the Country parameter.

The next step is to assign default values. A default value makes it easier for users to work with reports because it makes the most probable value the user will chose the default value. For example, in this report users be selecting United States, so having United States being the default value makes it easier for the user to fill out the form.

Getting Started

Let us add the contact form to our Spring 3 MVC Hello World application. Open the index.jsp file and change it to following:

File: WebContent/index.jsp

<jsp:forward page="contacts.html"></jsp:forward>

The above code will just redirect the user to contacts.html page.

The View- contact.jsp

Create a JSP file that will display Contact form to our users.
File: /WebContent/WEB-INF/jsp/contact.jsp

<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<html>
<head>
    <title>Spring 3 MVC Series - Contact Manager</title>
</head>
<body>
<h2>Contact Manager</h2>
<form:form method="post" action="addContact.html">   

    <table>
    <tr>
        <td><form:label path="firstname">First Name</form:label></td>
        <td><form:input path="firstname" /></td>
    </tr>
    <tr>
        <td><form:label path="lastname">Last Name</form:label></td>
        <td><form:input path="lastname" /></td>
    </tr>
    <tr>
        <td><form:label path="lastname">Email</form:label></td>
        <td><form:input path="email" /></td>
    </tr>
    <tr>
        <td><form:label path="lastname">Telephone</form:label></td>
        <td><form:input path="telephone" /></td>
    </tr>
    <tr>
        <td colspan="2">
            <input type="submit" value="Add Contact"/>
        </td>
    </tr>
</table>  
  
</form:form>
</body>
</html>

Here in above JSP, we have displayed a form. Note that the form is getting submitted to addContact.html page.

Adding Form and Controller in Spring 3

We will now add the logic in Spring 3 to display the form and fetch the values from it. For that we will create two java files. First the Contact.java which is nothing but the form to display/retrieve data from screen and second the ContactController.java which is the spring controller class.



File: net.viralpatel.spring3.form.Contact

package net.viralpatel.spring3.form;
  
public class Contact {
    private String firstname;
    private String lastname;
    private String email;
    private String telephone;   

    //.. getter and setter for all above fields.

}

The above file is the contact form which holds the data from screen. Note that I haven’t showed the getter and setter methods. You can generate these methods by pressiong Alt + Shift + S, R.

File: net.viralpatel.spring3.controller.ContactController

package net.viralpatel.spring3.controller;   

import net.viralpatel.spring3.form.Contact;   

import org.springframework.stereotype.Controller;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.SessionAttributes;
import org.springframework.web.servlet.ModelAndView;   

@Controller
@SessionAttributes
public class ContactController {   

    @RequestMapping(value = "/addContact", method = RequestMethod.POST)
    public String addContact(@ModelAttribute("contact")
                            Contact contact, BindingResult result) {   

        System.out.println("First Name:" + contact.getFirstname() +
                    "Last Name:" + contact.getLastname());   

        return "redirect:contacts.html";
    }   

    @RequestMapping("/contacts")
    public ModelAndView showContacts() {   

        return new ModelAndView("contact", "command", new Contact());
    }
}

In above controller class, note that we have created two methods with Request Mapping /contacts and /addContact. The method showContacts() will be called when user request for a url contacts.html. This method will render a model with name “contact”. Note that in the ModelAndView object we have passed a blank Contact object with name “command”. The spring framework expects an object with name command if you are using
in your JSP file.

Also note that in method addContact() we have annotated this method with RequestMapping and passed an attribute method=”RequestMethod.POST”. Thus the method will be called only when user generates a POST method request to the url /addContact.html. We have annotated the argument Contact with annotation @ModelAttribute. This will binds the data from request to the object Contact. In this method we just have printed values of Firstname and Lastname and redirected the view to cotnacts.html.

That’s all folks

The form is completed now. Just run the application in eclipse by pression Alt + Shift + X, R. It will show the contact form. Just enter view values and press Add button. Once you press the button, it will print the firstname and lastname in sysout logs.

The Spring Framework is constantly evolving. Spring MVC has gotten easier and easier to work with and with the SpringSource Tool Suite it gets even easier to get a Spring MVC project up and running. Today I’ll show you how to setup a simple Spring MVC project and add some simple functionality to it.

There are a few things you’ll need to complete this tutorial:

Java JDK installed
SpringSource Tool Suite – I downloaded the installer version, not the plug-in to Eclipse

With those two items installed and ready go ahead and run the SpringSource Tool Suite and create a new project: File -> New -> Spring Template Project



Note: It might prompt you to download the template, go ahead and let it do that.



Once the project has been created we can test out the default Hello World code that is already in-place. Lets add the project to the SpringSource tc Server and then start it.



Once the SpringSource tc Server is up and running open a browser and head to this url: http://localhost:8080/EchoSpringMVC/

If everything went well you should see this:









You can leave the SpringSource tc Server running.

Open the HomeController.java file now and add the following imports:

import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.ui.Model;

Lets add a new mapping and method for the echo functionality we are going to add.

@RequestMapping(value="/echo", method=RequestMethod.GET)
public String echo(@RequestParam("input1") String input1, Model model) {
    logger.info("Calling echo");
    String output = "Echo: " + input1;
    model.addAttribute("output", output);
    return "echo";
}

We set the mapping to handle any GET requests to echo. The echo method takes one parameter called input1 which we simply use to complete the echo functionality. The echo is passed back to the view (which we will create next).

Your HomeController.java should look like this:

package com.giantflyingsaucer.springmvc;   

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.ui.Model;   

/**
 * Handles requests for the application home page.
 */
@Controller
public class HomeController {   

    private static final Logger logger = LoggerFactory.getLogger(HomeController.class);

      /**
     * Simply selects the home view to render by returning its name.
     */
    @RequestMapping(value="/", method=RequestMethod.GET)
    public String home() {
        logger.info("Welcome home!");
        return "home";
    }   

    @RequestMapping(value="/echo", method=RequestMethod.GET)
    public String echo(@RequestParam("input1") String input1, Model model) {
        logger.info("Calling echo");
        String output = "Echo: " + input1;
        model.addAttribute("output", output);
        return "echo";
    }
}

Lets add a new JSP page for our echo view. Right-click on the webapp/WEB-INF/views folder and select:
New -> Other -> Web -> JSP File



Here are the contents for the new echo.jsp file:

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ page session="false" %>
<html>
<head>
    <title>Echo</title>
</head>
<body>
<h1>
    <strong><c:out value="${output}"></c:out></strong>
</h1>
</body>
</html>

Save all the files and the SpringSource tc Server will reload the project automatically. When this has happened use this URL to trigger the echo: http://localhost:8080/EchoSpringMVC/echo?input1=HelloWorld

Your result should be:
