java.lang.LinkageError

[brock]

I've recently been getting a java.lang.LinkageError while calling a JSP (the
complete stack trace is below).

I'm using ServletExec as my Application Server--it creates a copy of the
classes in my COM directory and places them in the WEB-INF/classes dir. I'm
able to temporarily resolve this problem by deleting those created copies of
the class and restarting the server.

Anyone have any ideas on this?

Thanks!

The Javadoc says:
"Subclasses of LinkageError indicate that a class has some dependency on
another class; however, the latter class has incompatibly changed after the
compilation of the former class."
