Re: a question about rmi sample

I am currently in London and using an internet cafe to
answer. Therefor I don't have access to the code and
can't verify this. But...

I think you haven't compiled the attributes or haven't
included them in the classpath or haven't added it to
the search-path with Attributes.addSearchPath.
Basically the framework doesn't know that it should
marshal this object as a client stub and therefor the
object is incorrect on the client side.

If the error persists please answer back and I will
try to have a closer look at this when I get back from
London.

Btw, if any of you guys are in London tomorrow evening
come by XTC. I will be there and might give an
improvised speach on Nanning. See www.xpdeveloper.com

Tip: If you execute Nanning with assertions enabled
(using java -ea) better error-messages will appear.
