One other thing to be aware of is that if you installed Tomcat 4.1.x using the exe, and you chose to install Tomcat as a service, then the install would copy tools.jar from the JDK to Tomcat's common/lib directory. This allowed the service to run off the JRE associated with the JDK (much much easier to find via the Windows registry) instead of the JDK itself. I have seen cases where it was an old tools.jar in common/lib that caused this symptom when running Tomcat in a newer JVM.
