search the archives for more postings, but I have
heard different approaches when I posted the same
problem.

1. Check to see that you are using the latest Struts
nightly build.

2. If not using hte latest nightly build, this may
work if you use Tomcat 4.0

3. Remove Jaxp, crimson and parser.jar files and add
xerces.jar file.

The first one makes sense to me and the last two I am
puzzled about.

The main thing is that ActionMessage is a new class to
the nightly builds.  However this may be circumvented
(the use of the ActionMessage) by changing the JSP to
not use the new feature (at least this is what I have
been told).

Sorry if I am confusing you, but as you can probably
tell, i myself am confused, but since I do not have to
do the work immediately, I have been holding off
figuring out exactly what the problem is.
