Using a text editor. :-) Seriously, I guess you're using the fop.war in
docs/examples/embedding, right? The source code is in FopServlet.java.
Unfortunately, the WAR file is not built with the build script, so you
have to manually build the WAR file after adjusting the code. Actually,
it's not even necessary to build the WAR. It is sufficient to compile
FopServlet.java (you need to get servlet.jar from your web container to
do that) and place it (along with a web.xml file) in the right places.

And you don't need to get Avalon, since the necessary jars are in the
lib directory of FOP's distribution.

SAX has nothing to do with servlets. The SAX stuff is in xerces.jar. You
can get the servlet.jar from your web container or from here: 

To turn of logging you can also try to call
