I had created three files like

SimpleWS.java

package com.htc.htcws;

import javax.jws.WebService;
import javax.jws.WebMethod;
import java.rmi.Remote;
import java.rmi.RemoteException;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;


@WebService
@SOAPBinding(style=Style.RPC)
public interface SimpleWS extends Remote
{
@WebMethod
public String greet(String person)
throws RemoteException;
}

SimpleWSBean.java
package com.htc.htcws;

import javax.jws.WebService;
import javax.jws.WebMethod;
import javax.ejb.Remote;
import javax.ejb.Stateless;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;

@Stateless
@Remote(SimpleWS.class)
@WebService(endpointInterface="com.htc.htcws.SimpleWS")
@SOAPBinding(style=SOAPBinding.Style.RPC)
public class SimpleWSBean implements SimpleWS
{
@WebMethod
public String greet(String person)
{
return "Hi "+person+" all Good Wishes for Tamil New Year's Day";
}

}

SimpleWSClient.java

package com.htc.htcws;
import javax.xml.rpc.ServiceFactory;
import javax.xml.rpc.Service;
import javax.xml.namespace.QName;
import java.net.URL;
import org.apache.log4j.Logger;
import org.apache.log4j.FileAppender;
import org.apache.log4j.HTMLLayout;
import javax.xml.transform.stream.StreamSource;
import javax.xml.ws.Dispatch;
import javax.xml.ws.Service.Mode;
import javax.xml.ws.Response;
import java.io.StringReader;

public class SimpleWSClient
{
static Logger logger;

public static void main(String[] args)
{
final String _NAMESPACE = "http://htcws.htc.com/";
final String _SERVICE = "SimpleWSBeanService";


try
{
logger = Logger.getRootLogger();
logger.addAppender(new FileAppender(new HTMLLayout(),
"mylog1.log",true));


URL url =
new URL("http://127.0.0.1:10080/simpws/SimpleWSBean?wsdl");

QName qName = new QName(_NAMESPACE,_SERVICE);
if(args.length!=1)

{
System.out.print("Give the person-name as args[0]");
System.exit(1);
}



ServiceFactory sFactory = ServiceFactory.newInstance();

Service service = sFactory.createService(url,qName);

System.out.println(".."+service);

SimpleWS invoker =
(SimpleWS)service.getPort(SimpleWS.class);
System.out.println("##"+invoker);

String res = invoker.greet(args[0]);

System.out.println("Response is::"+res);
}
catch(Exception ex)
{
System.err.println("Caught the exception as"+ex);
}
}

}
