Thomas,
Thanks so much! That did the trick.
Just one thing: I had to replace the jar file in
${catalina_home}/common/lib as well as webapps/webswamp/WEB-INF/lib. I
think this is because I installed using the tgz source, and
install-webswamp.sh/build.xml(install-tomcat) puts things in the common
directory too.
Thanks again!
Don
