deploy above two classes by archieving in a jar and copy it to deploy folder of jboss then run ur jboss server with url http://localhost:8080/jbossws there u will get all ur web services running in your server. the client program will be like this

[code lang=”java”]
package com.crm.serviceClient;

import java.net.MalformedURLException;
import java.net.URL;

import javax.xml.namespace.QName;
import javax.xml.ws.Service;
import javax.xml.ws.WebEndpoint;
import javax.xml.ws.WebServiceClient;

import com.crm.bean.Employee;
import com.crm.services.EmployeeService;
/**

@WebServiceClient(name = "EmployeeServiceImplService", targetNamespace = "http://services.crm.com/",
wsdlLocation = "http://localhost:8080/jarfilename/EmployeeServiceImpl?wsdl")

}

public static void main(String[] args) throws MalformedURLException {

try {

if (service != null) {
System.out.println("Serrvice not null");

System.out.println(employee1.getFirstname());
System.out.println(employee1.getLastname());
}

} catch (Exception e) {
