I never got C2 to work with Tomcat 3.1 within the last 2 months. I
always got the same stack trace. It is a result from a
java.lang.VerifyError within the thread that asynchronously recreates
the sitemap. (You probably don't see the VerifyError any more because
the system.out logging code seems to have been removed. I haven't
actually checked this, though.)

But I finally managed to get Tomcat 4.0 to work properly (the trick is
to check out the correct jakarta-servletapi branch) and C2 works with
it like a charm.

BTW, a step by step HOWTO for installing Cocoon 2 and Tomcat 4.0 is
available from

if anyone is interested in it.
