so, if looks like I can use RMi via JNDI in JBoss. Here is what I have tried so far, and it is not working. Do let me know what I am missing: 1) defined a client / server / interface / iterface impl according to how it's done in RMI 2) packaged with other classes in my simple JBoss app. 3)in a servlet I am invoking the initialization methods for Server first, and then Client. 4) I am using InitialContext to bind and connect in the server / client (see sample below). 5) What am I missing? 6) Do I need an rmi policy file? any security permissions? I keep getting the following exception: Server exception thrown: javax.naming.CommunicationException: Could not obtain connection to any of these urls: 127.0.0.1:1099 and discovery failed with error: javax.naming.CommunicationException: Receive timed out [Root exception is java.net.SocketTimeoutException: Receive timed out]....... [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server 127.0.0.1:1099 [Root exception is java.net.ConnectException: Connection refused: connect]]] a snippet of my code is: MyClassImpl obj = new MyClassImpl(); MyClass stub = (MyClass) UnicastRemoteObject.exportObject(obj, 0); Properties env = new Properties(); env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); env.put(Context.PROVIDER_URL, "jnp://127.0.0.1:1099"); Context ctx = new InitialContext(env); ctx.bind("MyString", stub); the exception is thrown when binding, I have tried rebind also. I have similar code snippet for looking up the stub in client side too. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4166506#...
