Hello Patrick, Do you have DOM packages in WEB-INF/lib or WEB-INF/classes? If so, this violates the Sun classloading spec and, as of Tomcat 4.0.2, this is enforced....although not very cleanly until the latest betas of Tomcat 4.0.4 and 4.1. The solution is to move your DOM classes into a parent classloader such as TOMCAT_HOME/lib, TOMCAT_HOME/common/lib or use the ones that come from the JDK (if you use 1.4...either the default ones or ones you override in JAVA_HOME/jre/lib/endorsed...or TOMCAT_HOME/common/endorsed if you use Tomcat 4.1).
