2.0.2 -> 2.0.3: ClassNotFoundException on startup
I decided to get the src for 2.0.3 and did a build on it instead of the
2.0.2 I couldn't get to work. Now I'm getting different (but somewhat less
arcane) errors when starting.
in access.log:

Is this an easier one to eradicate? :)

Here is the second stacktrace:

Unfortunately (for you), I don't have redhat to experiment with and ran
out of suggestions... No, wait a second. I've got several more (assuming
you don't want to move to 4.0.4 right now):
1. Try with X running. Launch X and start tomcat under same user, and
(IIRC) not root.
2. Remove lib/optional/batik, build clean, build .... It will create
totally X-less setup.
3. Try Cocoon 2.0.3 release
These are all guesses because I can't imagine why class could not be
loaded.
PS I have Cocoon running with tomcat 4.0.4, mandrake, some Sun jdk.

Does *anything* works on your box?? :)
0. Do you use the *same* JRE to compile and run Cocoon?
1. Check that user you use to launch tomcat can read jars:
chmod 666 $TOMCAT_HOME/webapps/cocoon/WEB-INF/*
Or even: chmod -R 666 $TOMCAT_HOME/webapps/cocoon
2. Check that your java can read these jars:
java -cp $TOMCAT_HOME/webapps/cocoon/WEB-INF/cocoon-2.0.3.jar:...
org.apache.cocoon.Cocoon
If all is ok, should say:
Exception in thread "main" java.lang.NoSuchMethodError: main
Repeat same for org.hsqldb.jdbcDriver.
