[jboss-user] [JBossWS] - JSR181 Web Service Client

[chamillard]

Hi Folks,

I'm deploying a simple EJB 3.0 web service using the following code (based on the hello-jaxws sample that comes with the Java EE 5 distribution):

package endpoint;
  | 
  | import javax.ejb.Stateless;
  | import javax.jws.WebService;
  | import javax.jws.WebMethod;
  | 
  | @WebService
  | @Stateless
  | public class Hello
  | {
  |     @WebMethod
  |     public String getHello(String name)
  |     {
  |         return "Hello " + name + "!";
  |     }
  | }

I'm packaging it into a JAR and deploying to JBoss 4.0.4.GA, and the WSDL shows up fine from http://localhost:8080/jbossws. The WSDL name is as expected (http://localhost:8080/hello/Hello?wsdl).

I'm using wsimport to generate the client stub code using the following ant task:

  <target name="get-artifacts-windows" if="windows">
  |       <exec executable="${javaee.home}/bin/wsimport.bat">
  |           <arg line="-keep -d ./build/classes http://localhost:8080/hello/Hello?wsdl"/>
  |       </exec>
  |   </target>

This also seems to work as expected, and my test client (shown below) will compile.


  |  /* 
  |   * Client.java
  |   */
  | 
  | package client;
  | 
  | import javax.xml.ws.WebServiceRef;
  | import endpoint.jaws.HelloService;
  | import endpoint.jaws.Hello;
  | 
  | public class Client
  | {
  |     @WebServiceRef(wsdlLocation="http://localhost:8080/hello/Hello?wsdl")
  |     static HelloService service;
  |     
  |     public static void main(String[] args)
  |     {
  |         Client client = new Client();
  |         client.doHello();
  |     }
  |     
  |     public void doHello()
  |     {
  |         try
  |         {
  |             Hello port = service.getHelloPort();
  |             String ret = port.getHello(System.getProperty("user.name"));
  |             System.out.println("Hello result = " + ret);
  |         }
  |         catch(Exception e)
  |         {
  |             e.printStackTrace();
  |         }
  |     }
  | }

Unfortunately, when I try to actually run the client, I get the following:

[java] java.lang.NullPointerException
[java]      at client.Client.doHello(Client.java:28)
[java]      at client.Client.main(Client.java:21)

I added debugging statements and determined that the method generated by wsimport to get the port doesn't seem to be working properly, but that's as far as I can get!

Can anyone help me resolve this problem?

Thanks in advance,
Tim

PS I'm certainly willing to use wstools instead of wsimport, but I couldn't find an example for generating a client using a JAX-WS client (rather than a JAX-RPC client)
