configuration, full error stack trace is a starting point.
The problem reappeared just now.
As to the settings:
I didn't change any of the global settings of JBoss except activating TRACE in
log4j.xml. (I don' t even know how to change the class loading configuration.)
I am using JBoss 4.0.3SP1 (default) on Windows XP SP2 with JDK 1.4.2_10.
The error occurs when a MDBean calls a setter of a pretty trivial POJO.
The stack trace is attached below (some lines erased [...]).
Do you need any more information?
