JAX-WS Web Service Example Using Eclipse(STS)

In this tutorial , we will create hello world SOAP web service example in eclipse(STS). Eclipse (STS) provides good API for creating web services. Eclipse(STS) will do all work for you-creating WSDL, stub, endpoints etc.

Steps for creating web services in eclipse(STS):

1. Create new dynamic web project and name it "WebService".


2. Create new package named "com.dineshonjava.com"


3.Create a simple java class named "HelloWorld.java"
package com.dineshonjava.ws;

import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;

/**
 * @author Dinesh Rajput
 * Service Endpoint Interface
 */

@WebService
@SOAPBinding(style = Style.RPC)
public interface HelloWorld {
 @WebMethod 
 String sayHelloWorld(String name);
}


4. Right click on project->new->web service


5. Click on next.


In service implementation text box,write fully qualified class name of above created class (com.dineshonjava.ws.HelloWorldImpl) and move both above slider to maximum level (i.e. Test service and Test Client level) and click on finish. You are done!! A new project named "WebServiceClient" will be created in your work space.

6. Click on next.



7. Start Server.


8. After clicking start server,eclipse will open test web service API. With this test API, you can test your web service.




Note: Sometimes we get the following exception when we creating Web Service using Eclipse or STS

  1. Hi Dinesh,
    Please let me know the prerequisites for the above project (i.e. Webservice) to implement .
    For example jars or something similar to it or only the eclipse IDE suffices the need.
