I have not received any answer to my post. After I read Cactus
architecture, I am pretty sure that this problem is related to class loader.
I added one line of code as indicated below to print stack trace. The
exception is thrown from junit.framework.TestSuite(java.lang.Class). I can
get class name. But reflect can not get methods from class.
I never reach beginXXX method and test client never calls redirect
servlet. So the problem is related to class loader ore java reflect. I am
using VA 3.5.3 and cactus 1.2 or 1.3, and junit 3.7.
Your help is appreciated.
Jim
