The jars in server/lib and common/lib aren't the only jars important to
tomcat. Also look at the jars in the bin directory and take care to
remove older jars that have the same classes as the 5.5 release. It
might work to upgrade this way if you do a more thorough replacement.
Also I believe you have to also alter the way resources are defined in
your webapps when moving from tomcat 5.0 to 5.5.
My personal recommendation would be to do a normal install in a parallel
directory, copy the config files, altering port numbers so you can test
before switching over. When you are ready and everything has been
tested, reconfigure the port numbers in the new tomcat to match
production, move webapps over, drop the old production tomcat and start
the new one.

I upgraded from 5.5.20-->5.5.25 (RH linux) by copying new jars to
/common/lib and /server/lib
I then got these errors. Is this a bug in 5.5.25, or some sort of
problem with my upgrade method?
I'm now back to 5.5.20 jars and working fine again, but I'd like to
upgrade.
Any suggestions? Where is this dtd supposed to be?
Thanks.
