Hi Folks
I am trying to resolve a problem a few days and I am stuck here. I am relatively new to
webservices and trying to figure out what is the problem. I am using JBoss 4.0.5 GA which
has bundled JBossWS 1.4. When I run a webservice client I get an error. Note: I have used
"+++" to seperate peices of Source Code
Will appreciate if some one could point me to the problem. I am assuming that there is a
problem is with some mapping file ,because I am able to invoke the sayHello method via the
second method . Also I read same kind of problem faced by another person,but had no reply
posted
http://lists.jboss.org/pipermail/jbossws-users/2007-January/001196.html
Note - I picked up the server code from example stated in the URL below
http://www.soapui.org/jbossws/topdown_example.html
Thanks a ton in advance

I am invoking the webservice in 2 ways . One fetching the remote interface and one use a
CallImpl
My client code is as follows :-
+++++++++++++++++++++++++++++++++++++++++++++++
package helloworld.client;
import helloworld.*;
import javax.xml.rpc.Service;
import javax.xml.rpc.Call;
import javax.xml.rpc.ServiceFactory;
import org.jboss.ws.jaxrpc.ServiceImpl;
import org.jboss.ws.jaxrpc.CallImpl;
import org.jboss.ws.jaxrpc.encoding.*;
import javax.xml.namespace.QName;
import java.net.URL;
public class HelloClient
{
public static void main(String[] args)
throws Exception
{
String TARGET_NAMESPACE = "http://localhost:8080/HelloWorld";
String argument = "Kapilesh";
System.out.println("Contacting webservice at " + TARGET_NAMESPACE );
ServiceFactory factory = ServiceFactory.newInstance();
URL wsdlLoction = new URL(TARGET_NAMESPACE+"?wsdl");
QName serviceName = new QName(TARGET_NAMESPACE,
"HelloWorldService");
ServiceImpl service = (ServiceImpl)factory.createService(wsdlLoction,
serviceName);
QName operationName = new QName(TARGET_NAMESPACE, "sayHello");
//first method
IHelloWorld hello = (IHelloWorld) service.getPort(IHelloWorld.class);
// System.out.println("hello.hello(" + argument + ")");
System.out.println("output:" + hello.sayHello(argument));
CallImpl call = (CallImpl)service.createCall();
call.setOperationName(operationName);
// System.out.println(call.isParameterAndReturnSpecRequired(operationName));
// second method
Object retObj = call.invoke(new Object[]{argument});
}
}

I have deployed a webservice on a server and I am able to deploy it sucessfully...
