Our webapp is throwing a java.lang.IncompatibleClassChangeError when attempting
to load our servlet.  The class that is failing is a class contained in a
middleware jar file.  We are successful in accessing the very same class via 
code which executes outside of tomcat.

Any help would be greatly appreciated.
