I have encountered the following error when
running on Jboss 3.0. This error is related to the
functionality of a web application based on the
struts framework. The error occurs when the struts
framework attempts to load a class that is in the
classpath of the web application using the
Class.forName(String) method. The following is the
stack trace for the error.

Note the strange characters at the end of the error
message. Almost like the class is not able to be
read in for some reason. I have recompiled this
class and all classes in the project several times
and have experienced this error every time i re-
deploy them in the Jboss environment.
I was not having this problem with an early version
of jboss (jboss-3.0.1RC1 I believe) It occured as
soon as I upgraded.

Try to post a war that shows this problem as this info doesn't
really help much.
