It looks like xalan / xerces helper classes are not found. Most
likely, you are running jdk 1.4 that comes with some out-of-date xalan
/ xerces classes that got mixed up with the ones provided by Apache
Cocoon. Or the ones provided by Apache Tomcat got mixed with the
Cocoon ones.

Look for install instructions for your version of jdk / servlet

Generally, updating to the latest versions of Tomcat / Cocoon for
_your_ _JDK_ _version_ should solve this problem.


Please follow up summarizing your problem and which suggested solution
