Derek,
Glad to see the problem was easily solved. Regarding setting the Threads
ContextClassLoader - I've already done that in the latest CVS. I needed to do it
because of
the way the SAX factory finds a parser implementation.
However, I will look at adding only .jar files - I guess I thought I did that, but
guess I overlooked
it. I would like to see your changes regarding log4j and correct initialization when
/bin is not
the working directory.
