Send a RMI request to JMS

Question

Dear All
I need to develop a server, which receives a request from its clients, then uses the data to create a jms message, then publish it to a JMS queue.
This is my design:
1. start up the server, in the initialisation stage, it will pass a topic name to a jms handler which is similiar to SimpleTopicPublisher in the jms tutorial, this handler will firstly creates a JNDI API InitialContext object, then looks up connection factory and topic.
2. When a request comes in, it passes the request to jms handler, so that it publishes a message.
Sounds easy enough?
But when I tried to run the server, the jms handler failed to create the context. The exception I got was javax.naming.NoInitialContextException: Cannot instantiate class: com.sun.enterprise.naming.SerialInitContextFactory [Root exception is ...
But if I run the jms handler individually, it is ok.
Do you have any ideas about this? Can I ask you to provide some sample codes if you know the answer if it is possible?
Thanks in advance

Ok, here is the source code:

          super();
          System.out.println("about to create adapter");
          adapter = new Adapter("MyTopic", "TestTopic");
     public String findProperty(String aName) throws java.rmi.RemoteException
     adapter.publishMessage(nextID, "findProperty", aName);     
// do some work to get a result back
     return result;
public static void main(String[] args)
          System.setSecurityManager(new RMISecurityManager());
          try
               ServerInterface si = new Server();
               Naming.rebind("//localhost/servername", si);
          catch (Exception e)
               System.out.println("Server failed to start...");
