Java EE (Java Enterprise Edition) General Discussion

hi

i am very new to web services.
I am exposing my ejb3.0 components as web services.
I am using myeclipse ide 5.5 that prvides service explorer utility where i could test my web services.web methods works fine.i am using JBOSS 4.0.5GA app server
But when tried to access web services using client application,it throws following exception,

Caused by: org.jboss.ws.WSException: Cannot obtain java type mapping for: {http://wb1-329:8080}validateUser

can anybody tell me where i went wrong?

following is my client application code snippet,

String namespace="http://wb1-329:8080";
String service="CustomerRegisteration";
String wsdl="http://localhost:8080/CustomerRegistrationEJB?wsdl";

//ctx=new InitialContext();
//customerSessionRemote remote=(customerSessionRemote)ctx.lookup("customer/remote");
//String user=remote.validateUser(getUserName(), getPassword());

try {
URL defurl = new URL(wsdl);
System.out.println(defurl);
ServiceFactory serviceFactory=ServiceFactory.newInstance();
System.out.println("service fact");
Service remoteService=serviceFactory.createService(defurl, new QName(namespace,service));
System.out.println(remoteService);

customerSessionRemote invoker=(customerSessionRemote)remoteService.getPort(customerSessionRemote.class);
System.out.println(invoker);
String user=invoker.validateUser(getUserName(), getPassword());
if(user!=null)
{
if(user.equals("manager"))
{
res="manager";
}
else
{
res="executive";
}
}
else
{
res="failure";
}
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

} catch (ServiceException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
