Hi Vincent and Dave, Sorry, I had take mistake.

My only concern with this approach is any threading issues? I wrote such kind of Servlet Test Runner before, and find it. I don't use this Servlet Test Runner because I decided to not use browser interface. So, the classes are not maintaind for a long time. However, I think this is good enough for the stat point.
