tomcat-3.2.3: NoSuchMethodError

I developped a piece of code and would like to wrap it in a servlet. When testing the program from the commandline (using main), everything works fine. But whet I test it from the servlet, I get a NoSuchMethodError.
I'm wondering if this could be a classpath-issue, due to the fact that tomcat uses it's own jars?
Thanx for every hint!

Yep, I'd check out the CLASSPATH. The rules on what gets into a JSP/servlet's CLASSPATH change from Tomcat 3 to Tomcat 4, and I believe that conflicts with different DOM classes may have been one of the reasons why!

move xerces.jar into the tomcat's lib directory and delete the dom1 parsers parser.jar and jaxp.jar (or rename them in z_parser.jar and z_jaxp.jar., but tomcat-3.x should only use one xml parser.
It is sorta covered in the JavaRanch Style Guide.
