Invoke .NET components as web services.

Steps:

1. Open Visual Studio .net editor

2. Click on File->New->Website -> Asp.net Webservice

3. Add web methods.

4. Build -> Build Solution.

5. Debug -> start without debugging.

Click service description-> copy the url.

6. Open Visual Studio .net editor

7. Click on File->New->Website -> Asp.net Website

8. Design view -> design your page. (add a button where we to write code that invokes web

method)

9. Code view -> add this line -> localhost.service Mycalc = new localhost.service();

10. mycalc is just a reference name – userdefined.

11. To invoke the web methods use the reference name. Say if u have add as a web method u can

invoke add using [myclac.add()]

12. to make this work , initially in Solution Explorer -> right click on C:\...\website.. -> select add web

reference -> now a dialogue box opens.

Here paste http://localhost:49158/WebSite2/Service.asmx?WSDL ( this is actually the url copied )

Then click go -> then click Add reference.

Now -> build -> build solution and start without debugging.

http://localhost:49158/WebSite2/Service.asmx?WSDL

Invoke EJB components as web services

http://wiki.netbeans.org/CreatingEJB3UsingNetbeansAndGlassfish

Install NETBeans 6.5

http://wiki.netbeans.org/CreatingEJB3UsingNetbeansAndGlassfish

Change Return null to “Hello EJB World” with in quotes

/*

* To change this template, choose Tools | Templates

* and open the template in the editor.

*/

package Stateless;


@Stateless

public class TestEJBBean implements TestEJBRemote {

public String getMessage() {

return "“Hello EJB World" ;

} // Add business logic below. (Right-click in editor and choose

// "Insert Code > Add Business Method" or "Web Service > Add Operation")

}

Using the Web Module as EJB Client

We have already created the Web Module previously when the EAR has been created, so let’s

use it as EJB Client.

When the Web module is created, by default Netbeans already creates a file called index.jsp in

the Web Pages section. Open this file to add a call to the servlet. The code looks like below:

Now Test1-war

Index.jsp

Add code :

<a href="TestServlet">Click here to call the EJB component</a>

As you can see, we must create a servlet called TestServlet. it will call the EJB component when

the link from User Interface is clicked.

To create the servlet itself, right click on Web project (in my case Test-web), New -> Servlet.

On the new screen, select the Class Name and the Package. On next screen, you can keep all

options and click on Finish button. The Servlet will be created and its code will appear on the

Main tab.

Add these Header file

import java.io.*;

import javax.ejb.EJB;

import javax.servlet.*;

import javax.servlet.http.*;

import stateless.TestEJBRemote;

@EJB

private TestEJBRemote testEJBBean;

Change Process Request to goGet at there places

remove this part of coding from comment line and change the code

from:

out.println("<h1>Servlet TestServlet at " + request.getContextPath () + "</h1>");

To:

out.println(testEJBBean.getMessage());

now clean and build , then run

O/P:

methods.

Step 4: Build solution

Debug->start without debugging.

Copy the wsdl link.

Step 5: web service client

Click on new -> new web service client

Paste the wsdl link

Give the name of the package

Click finish

Step 6: browse index.jsp

Right click->select call web service

Select the operation and click ok

Write the required code

This creates the client

EX-NO:8 DEVELOP A .NET CLIENT TO ACCESS A J2EE WEB

SERVICE

AIM: To Develop a .NET client to access a J2EE web service

PROCEDURE:

Create a Java Web Service (Java EE, JAX-WS)

1. Create a new Web Application

In the NetBeans 6.1 IDE, choose File –> New Project. In the New Project Dialog select the Web category, and choose

Web Application from the projects list. Then, Click Next.

* If the web category is not available in this dialog, it means that the NetBeans version you have installed isn’t the

Web and Java EE package.

In the Name and Location page, set the location where you want to create the web application, and provide a name

for the project. Click Next.

In the Server and Settings page, leave the default settings (Java EE 5, Use GlassFish V2) and Click Finish.

This creates the initial web application and opens the project for editing.

2. Create the Web Service

Add a new web service to the project. Right click the project node and choose New –> Web Service.

* Notice that the location of the Web Service option in the menu may change from this image and your IDE.

In the New Web Service dialog, provide the Web Service Name, and the Package. The name of the service will affect

the final URL for calling the service, and the package name will be the namespace of the service contract. Click Finish.

The Web Service now appears in the project tree.

To implement the service, double click the service node in the project tree (in the figure above – CalculatorService).

This will open the Web Service in Design mode, that lets you graphically design your service.

Change to Source View by clicking on the Source button in the upper toolbar, and this will open the

CalculatorService.Java file for editing. Here is a sample implementation of the service. Notice how Java Annotations

are similar to .Net Attributes, especially how similar they are to the Web Services attributes we know…

package org.bursteg.calculator; import javax.jws.WebMethod; import javax.jws.WebParam; import javax.jws.WebService; @WebService public class CalculatorService { @WebMethod public int Add(@WebParam(name="a") int a, @WebParam(name="b") int b) { return a + b; } }

Deploy the web service to the web application server. From the NetBeans IDE this is done by right clicking the

project node, and choosing Undeploy and Deploy.

After the web application has been deployed, just to make sure the web service works as expected, you can right

click the web service node, and choose Test Web Service.

This will open the browser and navigate to a test page with the url of the service

(http://localhost:9232/Calculator/CalculatorServiceService) with a ?Tester suffix.

http://localhost:9232/Calculator/CalculatorServiceService

Call the Java Web Service from a .Net Client

In Visual Studio 2008, create a new console application.

This creates a new solution with a single Console Application project in it.

Right click the project node and choose Add Service Reference.

In the Add Service Reference Dialog, paste the address of the service metadata endpoint (service address + ?wsdl

suffix: http://localhost:9232/Calculator/CalculatorServiceService?wsdl), and click Go. The dialog will get the service

metadata and understand the service contract.

http://localhost:9232/Calculator/CalculatorServiceService?wsdl

Provide a namespace for the service reference, and click OK.

This will generate the client side proxy that lets you consume the service easily, and the required configuration

settings into the configuration file.

To call the service using the generated client side proxy, open Program.cs and use the following code:

static void Main(string[] args) { CalculatorServiceClient proxy = new CalculatorServiceClient(); int result = proxy.Add(2, 3); Console.WriteLine("Calculator Service returned: " + result.ToString()); }

Run the program and see that the web service is being called and the result is correct.

Conclusion

Since Java EE Web Services (JAX-WS) are standard SOAP services, they are easily interoperable from a .Net client

application with only several clicks. Visual Studio generated a .Net client proxy that makes it very easy to connect

and call the service.

RESULT:

Thus an experiment to Develop a .NET client to access a J2EE web service has been successfully

executed.
