Hi.
I have upgraded my Struts application from 1.2 to 1.3.10.
With minor problems at first it finally worked. Suddenly it stopped working
and I guess it must be after restart of the service.
I guess it is a problem with versions of the jar file, but I am not sure.
Does anybody have an idear, as I am ready to hang myself.
I now get the following error message:
2010-05-26 10:41:20 org.apache.struts.chain.commands.ExceptionCatcher
