SOAP WebService Using Apache CXF Example with Service and Client (Bottom To Top Approach)

=>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

=>WSDL : {http://iton.com/}FirstServiceImplService ,click on this link,WSDL of this service will display as follows

=>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
