=>First Develope One interface.Develope your own methods.
=>These methods i want to expose as a FirstService
=>Just Create Normal Java interface with @WebService Annotation only
package com.service;
import javax.jws.WebService;
@WebService
public interface FirstService {
public String methodOne();
public int methodTwo();
}
=>Provide the implementation for Above Interface
=>Just add extra annotation @WebService(endpointInterface="com.service.FirstService")
End point means interface name with package only
package com.service.impl;
import javax.jws.WebService;
@WebService(endpointInterface="com.service.FirstService")
public class FirstServiceImpl implements FirstService {
public FirstServiceImpl() {
System.out.println("+++++From FirstServiceImpl+++");
}
@Override
public String methodOne() {
System.out.println("+++From FirstServiceImpl methodOne()+++");
return "k fine";
}
@Override
public int methodTwo() {
System.out.println("+++From FirstServiceImpl methodTwo()+++");
return 100;
}
}
=>Add Maven Dependencies for Spring with Apache CFX

=>Deploy the Project into the server(Tomcat or any other)
=>After deployment successfull this file will generate automatically.
=>It is the responsibility of apache cxf to identify webservice annotation and convert our java programs into wsdl file as webservice .
=> All Services exposed by us is displayed in this file,This is the WSDL file
=>By using this url only we can generate java files(By using these java files only client can communicate with this service)
=>Copy the url(http://localhost:8090/SoapServiceExample/firstService?wsdl) and go to command prompt
and use this command to generate java programs(or Stubs).
=>wsimport -keep -s D:\eclipseWorkspace\SOAP\SoapServiceClientExample\src http://localhost:8090/SoapServiceExample/firstService?wsdl
=>D:\eclipseWorkspace\SOAP\SoapServiceClientExample\src. I am just telling where to copy those generate java files for client program,I am using eclipse so that i put these java files directly into my eclipse work space
=>SoapServiceClientExample is my client project for to access the services.
=>Client Program
package com.iton.client;
import com.service.FirstService;
import com.service.impl.FirstServiceImplService;
public class FirstServiceClient {
public static void main(String args[]) {
//Getting FirstServiceImplService class,In stubs automatically class extension adding with Service
FirstServiceImplService firstServiceImplService=new FirstServiceImplService();
//From this Service class we are getting our Interface by using getFirstServiceImplPort(),in stubs our class preceeds with get and extension as Port is created automatically
FirstService firstService=firstServiceImplService.getFirstServiceImplPort();
//From interface calling methods
System.out.println("From FirstSrvice methodOne::"+firstService.methodOne());
System.out.println("From FirstSrvice methodTwo::"+firstService.methodTwo());
}
}
Output:
From FirstSrvice methodOne::k fine
From FirstSrvice methodTwo::100
