: java.lang.IncompatibleClassChangeError: Implementing class

Given the definition of IncompatibleClassChangeError[1], it sounds like
you have a rogue JAR or classfile somewhere in the classpath.  If you're
upgrading from Tomcat 4 -> 5 beware of lingering v4 code.

Check the various "endorsed" dirs, as people sometimes put JARs there
out of desperation and then forget about them.

Also, this looks odd:

:         <classpath id="jspc.classpath">
:             <pathelement path="${env.JAVA_HOME}/lib/tools.jar"/>

I don't know whether it's "wrong," just that my precompilation works
without it. =)


:             <fileset dir="${env.CATALINA_HOME}">
:                 <include name="jasper-compiler.jar"/>
:             </fileset>

Wouldn't this be "common/lib/jasper-compiler.jar" ?
-and wouldn't you also need servlet-api.jar and jsp-api.jar?

   Thrown when an incompatible class change has occurred to some class
   definition. The definition of some class, on which the currently
   executing method depends, has since changed.
