RE: Which logging library is needed to run fop 0.20.4 servlets
Answering my own question in case someone else encounters this problem too. I worked around the problem by rebuilding the FopServlet. My conclusion is that the FOPServlet class file in the distributed war file is incorrect.

Yes I use the FOPServlet from the distribution (the WAR file in the example directory).

Logging has changed from 0.20.3 to 0.20.4. We were able to eliminate the need for logkit.
