Benedikt,
I think you should start debugging in the runtime environment.
Can you start JBoss/tomcat with the extra JVM argument '-verbose:class'
(without quotes) to see where the classes are loaded from.
It looks lilke com.ecyrd.jspwiki.plugin.WikiPlugin is loaded by two
different classloaders.
regards,
Harry
