    Swing Client problem

    Vinicius Carvalho Apprentice

      Hello there! I'm trying to use a Swing project as a client to my EJB3 sample project. I have jdk1.6 (and I have the patch for jboss-remoting and jdk1.6).
      My client project runs smoothly on Eclipse and a simple testcase class, but when I started a netbeans client I'm having problems with it. I'm pretty sure I forgot a jar somewhere (since my eclipse client runs inside the ejb3 project of my jboss ide).
      I get the stub from the jboss, but when I invoke a method it throws a ClassNotFoundException:

      Any ideas?

      Regards

      Here's the libs I've put on my netbeans project:

      appClient.jar (it has my persistence classes and remote interfaces)
      jboss-aop-jdk50-client
      jboss-aspect-jdk50-clilent
      jnp-client
      ejb3-persistence
      jboss-remoting

      But I'm getting this error when I hit an action:

       InitialContext ctx;
       try {
       ctx = new InitialContext();
       CatalogService catalogService = (CatalogService)ctx.lookup("CatalogBean/remote");
       Product[] products = catalogService.getProductList();
       int index = 0;
       for(Product p : products){
       jTable1.getModel().setValueAt(p.getId(),index,0);
       jTable1.getModel().setValueAt(p.getName(),index,1);
       jTable1.getModel().setValueAt(p.getPrice(),index,2);
       index++;
       }
       index=0;
       } catch (NamingException ex) {
       ex.printStackTrace();
       }
      

      I get this exception:
