Web services in Java: Create a SOAP web service and test in SOAP UI

1] Create WSServiceHello Endpoint Interface:

WSServiceHello.java

package com.dineshonjava.ws;

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService
public interface WSServiceHello {
 @WebMethod
 String sayHello(String name);
}

2] Create WSServiceHello Endpoint Implementation class:
WSServiceHelloImpl.java

package com.dineshonjava.ws;

import javax.jws.WebService;

@WebService(endpointInterface = "com.dineshonjava.ws.WSServiceHello")
public class WSServiceHelloImpl implements WSServiceHello {
 @Override
 public String sayHello(String name) {
  return "Hello, Welcome to JAX-WS World and keep learning!! " + name;
 }
}

3] Create Endpoint Publisher class:
WSHelloPublisher.java

package com.dineshonjava.publisher;

import javax.xml.ws.Endpoint;
import com.dineshonjava.ws.WSServiceHelloImpl;

public class WSHelloPublisher {
 // you can use any port no. 9090 or 9191 etc
 public static void main(String[] args) {
  Endpoint.publish("http://localhost:9090/WS/WSServiceHello", new WSServiceHelloImpl());
 }
}

/*

1]access wsdl file by typing the following in url
http://localhost:9090/WS/WSServiceHello?wsdl


2]References:
http://www.dineshonjava.com/2013/06/jax-ws-hello-world-example.html
and
http://java.dzone.com/articles/jax-ws-hello-world
(Both are same program)

3]Search for 'service name' and 'portType name' in wsdl file

(1)While creating client, create object of 'service name' ie. <service name="WSServiceHelloImplService">
(2)Also create object of 'port name' ie. <portType name="WSServiceHello">

*/

4] Run WSHelloPublisher.java program.Your web service is published.
You can check your wsdl at
http://localhost:9090/WS/WSServiceHello?wsdl

Developing WebService Client

1] we need to generate the client stubs.

- Create a new project in eclipse.

- Open your command line, and enter the wsimport command in cmd:

CD <path of new project>\src

wsimport -keep http://localhost:9090/WS/WSServiceHello?wsdl

Click the image to zoom

you will find java classes generated and compiled under src->com->dineshonjava->ws

Note: You may face the following error
wsimport is not recognized as an internal command
Soln: Follow these steps
Update your PATH variable
1)Go to My computer >> right click and select properties.
2)On the properties tab select Advanced system settings
3)Click enviroment variables
4)select path and click edit option
add
";C:\Program Files\Java\jdk1.7.0_60\bin"
at the end.
5)close the cmd and try again.
Done.

2] Lets create client class now.
create WSHelloClient.java under src->com.dineshonjava.client

WSHelloClient.java

package com.dineshonjava.client;

import com.dineshonjava.ws.WSServiceHello;
import com.dineshonjava.ws.WSServiceHelloImplService;

public class WSHelloClient {

 public static void main(String[] args) {
  WSServiceHelloImplService service = new WSServiceHelloImplService();
  WSServiceHello serviceHello = service.getWSServiceHelloImplPort();
  System.out.println("***************Call Started*******************");
  System.out.println(serviceHello.sayHello("Rahul "));
  System.out.println("***************Call Ended*********************");
 }

}

Output:
3] Run above program and you will get the output in console.
***************Call Started*******************
Hello, Welcome to JAX-WS World and keep learning!! Rahul
***************Call Ended*********************

Now Webservice is started and is ready to be tested.

Test in SOAP UI

1) Open soap ui.

2) Right click project and click new SOAP project.
