RE: IS it possible to avoid JNDI call to get context for ConnectionFactory

The lookup refers to a JNDI lookup. E.g:
    Hashtable properties = new Hashtable();
    properties.put(Context.INITIAL_CONTEXT_FACTORY, 
                   "org.exolab.jms.jndi.InitialContextFactory");
    properties.put(Context.PROVIDER_URL, "rmi://localhost:1099/");
    Context context = new InitialContext(properties);

    QueueConnectionFactory factory = 
      (QueueConnectionFactory) context.lookup("JmsQueueConnectionFactory");

To construct a connection factory directly,  you need to construct a
org.exolab.jms.client.JmsQueueConnectionFactory 
or org.exolab.jms.client.JmsTopicConnectionFactory, with the appropriate
connector parameters. In order to determine the connector parameters,
you'll have to examine the openjms source, as described previously.
