InvalidClassException ???

[mikaelmhz]

Hi!
I have my first try on clustering ejb's. An got som problems i cant figure out to resolve.

I have two instances running on my machine (NT 4.0).
The seems to be configured succesfully the two cluster members can see the other when starting and dropping them.

My trouble comes when i try to loockup a bean in the cluster. I catch InvalidClass exception.

There is no difference in the ear file containing the bean.

Make sure:
- you are using a recent version of jboss and not an oldies
- use, for your client, the JARs in the JBOSS_HOME/client folder that correspond to the server that is running i.e. don't mix client/server JARs that are not from the same version!

Cheers,
