      I am using JDK 1.3.1, and JBoss 2.4.4 is running un JRE 1.3.1

      I am getting a strange Exception:

      get context
      lookup factory

      ***************************
      Here is the SourceCode:

      Properties props= new Properties();
      props.setProperty( "java.naming.factory.initial" , "org.jnp.interfaces.NamingContextFactory");
      props.setProperty( "java.naming.provider.url" , "jnp://servix:1099");
      props.setProperty( "java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");

      System.out.println("get context");
      InitialContext context = new InitialContext( props);

      System.out.println("lookup factory");
      TopicConnectionFactory topicFactory = (TopicConnectionFactory)context.lookup("TopicConnectionFactory");


      **************************************************
      According to the online documentation i have to inlcude jms.jar into the classpath (from the lib/ext directory), but there is no such file in the jBoss 2.4.4 distribution.
