Subject: PropertyMessageResourcesFactory not found?!
I have a strange problem with PropertyMessageResourcesFactory not being
found when I run JspC from Ant. This is against tomcat5 (5.0.30-6jpp)
from the JPackage project, on RedHat EL 3.0, with IBM's 1.4.2 JDK (x86).
Two projects, both with very similar build files - one works fine
against Tomcat5, the other doesn't. Now, the other builds fine against
tomcat4 (4.1.x), also installed from JPackage. I am at a loss .. Here's
the stacktrace I get:

When I attached Eclipse's debugger to my Ant process, I found that
MessageResourcesFactory.createFactory() was returning null, after
catching a ClassNotFoundException - and PropertyMessageResourcesFactory
was the class it was trying to load.
I have no idea here ... struts.jar and struts-el.jar are both in
WEB-INF/lib, it obviously can find the class when I compile against
tomcat4, so I am guessing there's a JAR conflict somewhere .. but the
Tomcat installations don't have any struts components (I didn't install
any of the admin webapps) - searching the entire drive system for
struts.jar and struts-el.jar only finds the files I have in my projects'
WEB-INF/lib, the file itself doesn't appear corrupted, md5sum seems to
be OK. I dunno what's goin' on ... the project deploys & builds fine
locally against 5.0.28 on Mac OS X & WinXP - so the build file seems
like its OK.
Obviously, I am at a standstill, any pointers would be appreciated. I
did find some bugzilla mentions in the Tomcat project about similar
sounding problems with Tomcat 5.5.x - any chance that that stuff crept
into 5.0.30?
