Can someone please help?
I'm guessing that the problem I'm seeing is rather common...
I am running on WebLogic7 and have put log4j into a small test app.
Prior to adding log4j, everything runs fine.
After putting in log4j into a State class that is passed from the server
side to my rmi client, I begin to see errors.
My State.java has something like:
private static Logger log = Logger.getLogger(
"org.tiaa.logpoc.catalog.statecatalog.model.State" );
The errors I begin to see are:
java.io.InvalidClassException:
org.tiaa.logpoc.catalog.statecatalog.model.State;
Local class not compatible: stream classdesc
