Thank you for you answer. I took a look at JNDI and it looks a lower level solution where you have to code more. I saw several examples on the internet on how to create a client for a web service and I can make them work also on my small piece of code above. The problem is that I can't make a web service calling another web service. It sounds to me a very basic functionality, but I was really able to find a complete example on how to do that. I tried to copy and paste the code of my client inside the HelloWorld.getHiWorld() method, but I keep getting a proxy error. How people normally make more webservices communicating between each other? any example from where I could get an idea?

This is my updated code with the client :


 HelloWorldImpl.java 
package hw1;

import hw2.HelloWorld2;

import java.net.MalformedURLException;
import java.net.URL;
import javax.jws.WebService;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;


@WebService(serviceName="HelloWorldService", name="HelloWorld")
public class HelloWorldImpl implements HelloWorld   {

    @Override    public String getHiWorld() {

        URL url=null;
        try {
            url = new URL(" http://localhost:8080/HelloWorld2WS/HelloWorld2Service?wsdl http://localhost:8080/HelloWorld2WS/HelloWorld2Service?wsdl");
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        QName qname = new QName(" http://hw2/ http://hw2/", "HelloWorld2Service");
        Service    service = Service.create(url, qname);
        HelloWorld2 port = service.getPort(HelloWorld2.class);

        return "Hi World" + port.getHiWorld();
    }

    public HelloWorldImpl() {

    }

}




HelloWorld2Impl.java

package hw2;

import javax.jws.WebService;

 @WebService(serviceName="HelloWorld2Service", name="HelloWorld2")
public class HelloWorld2Impl implements HelloWorld2 {

    @Override
    public String getHiWorld() {
            return " again!";
     }

public HelloWorld2Impl (){}
}




HelloWorldClient.java

package client;

import hw1.HelloWorld;

import java.net.URL;

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



public class HelloWorldClient {
    public static void main(String[] args) throws Exception {
        URL url = new URL(" http://localhost:8080/HelloWorldWS/HelloWorldService?wsdl http://localhost:8080/HelloWorldWS/HelloWorldService?wsdl");
        QName qname = new QName(" http://hw1/ http://hw1/", "HelloWorldService");

        Service service = Service.create(url, qname);

        HelloWorld eif = service.getPort(HelloWorld.class);

        System.out.println(eif.getHiWorld());

    }

}


Finally, this is the error my JBoss server is giving me:


Exception in thread "main" javax.xml.ws.soap.SOAPFaultException: hw2/HelloWorld2
    at com.sun.xml.internal.ws.fault.SOAP11Fault.getProtocolException(SOAP11Fault.java:178)

    at com.sun.xml.internal.ws.client.sei.SyncMethodHandler.invoke(SyncMethodHandler.java:108)
    at com.sun.xml.internal.ws.client.sei.SyncMethodHandler.invoke(SyncMethodHandler.java:78)
    at com.sun.xml.internal.ws.client.sei.SEIStub.invoke(SEIStub.java:129)
    at $Proxy19.getHiWorld(Unknown Source)
    at client.HelloWorldClient.main(HelloWorldClient.java:25)



Thank you!
