javac not creating stubs for RMI

Im looking into RMI for a university project, and ive run into a bit of a problem. From what ive read, java version 5 and up should generate the necessary stub files automatically (as i understand there was previously an additional step required).

However after following this tutorial here http://download.oracle.com/javase/6/docs/technotes/guides/rmi/hello/hello-world.html and compiling my classes with Javac, ive only got the standard class files, no sign of my stub files.

This is confirmed when i try and run my project, my application crashes saying that it cant find any stub files. Am i missing something?

NB, running java -version gives me this:

java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b07)
Java HotSpot(TM) 64-Bit Server VM (build 17.0-b17, mixed mode)
Solution

  • I believe you used something like

    RemoteInterface stub =
(RemoteInterface) UnicastRemoteObject.exportObject(server);

    in your server, instead of

    RemoteInterface stub =
(RemoteInterface) UnicastRemoteObject.exportObject(server, 0);

    Note two arguments to exportObject() -- second version returns different type. It indeed make difference for me.
