Hi all,

I'm trying to get sun's RMI hello world
( http://java.sun.com/javase/6/docs/technotes/guides/rmi/hello /hello-world.html)
to work under eclipse.

This works without problems, but only if i start the rmiregistry from the
root of the class tree. (I use a command shell (linux) to start
rmiregistry outside of eclipse.) In this case, i don't need to specify a
value for the codebase property when starting the server. I don't like
this solution because of its ad-hoc-ness, and i would rather set the
codebase property instead and start the rmiregistry from anywhere.

In my run configuration i use the VM argument

-Djava.rmi.server.codebase=file:${workspace_loc:/HelloRMISer ver/}

but that doesn't work, i get an exception when starting the server:

Server exception: java.rmi.ServerException: RemoteException occurred in
server thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested
exception is:
java.lang.ClassNotFoundException: example.hello.Hello
(etcetera...)

What am i doing wrong? What is the correct run-configuration to run an RMI
server in eclipse?

Thanks in advance. Michiel.

Michiel,

Are your .class files in the bin folder of the project? Should it maybe
be like this instead:
-Djava.rmi.server.codebase=file:${workspace_loc}/HelloRMISer ver/ Should
it maybe be file:./? Are you sure it's supposed to be a URI?

Hi Ed,
Thanks for your input.

the class files are alongside the source files in the same directories
(standard eclipse behavior)

> be like this instead:

i tried that, it didn't work

> it maybe be file:./? Are you sure it's supposed to be a URI?

that would be illogical: ${workspace_loc} returns the absolute file system
path of the workspace root. Nevertheless i tried that but it didn't work.

regards, Michiel

Problem solved: setting the VM args to

-Djava.rmi.server.codebase=file:${workspace_loc}/HelloRMISer ver/

(as you suggested, ed) was the solution...
Thanks for your input!
