Problem with Asyncronous Java Proxy

Question

Hi Friends,
My scenario is JAVA>XI>JDBC (Asyncronous Message).
I have imported the generated jar file and Created new Java Class (Invoke Proxy) in same project.Iam getting an error when I call this class from JSP .
When I use :
     Object ref = ctx.lookup("java:comp/env/ejb/VendorOut_PortTypeBean");
     queryOutHome = (VendorOut_PortTypeHome) PortableRemoteObject.narrow(ref, VendorOut_PortTypeHome.class);
     queryOutRemote = queryOutHome.create();
I am getting an error: NULL
(After Lookup  In Catch :null)
<u>InvokeProxy.java file:</u>
public class InvokeProxy {
     public String SendVendor(String VendorNumber, String LastName,String SearchTerm,String Currency,String Street,String City,String Zip,String Country )
          String Message = "";
          VendorOut_PortTypeLocalHome queryOutLocalHome = null;
          VendorOut_PortTypeLocal queryOutLocal = null;
          VendorOut_PortTypeHome queryOutHome = null;
          VendorOut_PortTypeRemote queryOutRemote = null;
          try {
               Properties p = new Properties();
               p.put(
                    Context.INITIAL_CONTEXT_FACTORY,
                    "com.sap.engine.services.jndi.InitialContextFactoryImpl ");
               p.put(Context.PROVIDER_URL, "server:port");
               p.put(Context.SECURITY_PRINCIPAL, "Administrator");
               p.put(Context.SECURITY_CREDENTIALS, "password");
               InitialContext ctx = new InitialContext();
                Message = "before Lookup";
               Object ref = ctx.lookup("java:comp/env/ejb/VendorOut_PortTypeBean");
