Subject Re: NoClassDefFoundError Trying to Test Filter

```I am using the servlet 2.3 version of the cactus jar.  The stack trace I
included in my first post actually showed that the FilterRedirector is
executed.

C:\projects\Metrics\src\lib>jar tvf cactus.jar | grep Filter

What's got me so confused is that it can find the
FilterTestRedirector.class class file, but it can't find the superclass
of my test class (FilterTestCase).

At first, I thought that it might be caused by the fact that the
AbstractTestCaller class is calling Class.forName() to load the test
classes since this will not work if the class calling forName was loaded
the class passed as the argument to forName().  But both cactus.jar and
my test classes are served by the same classloader, so I don't think
this is the problem.

I also tried changing the AbstractTestCaller to use the 3 arg version of
arg.  This didn't help either, in fact I verified that the ClassLoader
