This is what the JavaDoc says about java.lang.LinkageError
<snip>
Subclasses of LinkageError indicate that a class has some dependency on another
class; however, the latter class has incompatibly changed after the compilation
of the former class.

So I guess you compiled your TC4 against the 2.2 Servlet API and _then_
changed to the Servlet 2.3 API, try and recompile TC4 and make sure you
don't have the old Servlet API in your classpath.
