I've seen a couple posts regarding this type of error but their resolutions haven't solved our issue though. We're testing our install using a very simple example EJB. The client looks like this (not complete code):
// preparing properties for constructing an InitialContext object Properties properties = new Properties(); properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); properties.put(Context.PROVIDER_URL, "jnp://69.57.141.196:1099"); try { // Get an initial context InitialContext jndiContext = new InitialContext(properties); System.out.println("Got context"); // Get a reference to the Bean Object ref = jndiContext.lookup("StringProcessor"); System.out.println("Got reference"); // Get a reference from this to the Bean's Home interface StringProcessorHome home = (StringProcessorHome) PortableRemoteObject.narrow (ref, StringProcessorHome.class); System.out.println("Got home"); // Create an Adder object from the Home interface StringProcessor sp = home.create();
