I have recently experienced this same limitation between WinRunner and .jsp pages. GUI Spy does not "see" any of the controls in a .jsp loaded into IE5, but will when loaded into Netscape Communicator 4. I don't have an answer yet.
Much as I would LOVE for that solution to work, it did not. I bought all browsers down bought up WinRunner and then the IE browser. The map is ignorant of the servlet controls and worse the NN controls will not map over the IE rendered controls. Preety much leaving me dead in the water!
I have my friend working with Mercury on this
and again any suggestions cheerfully accepted.
Smoke me a kipper, I'll be back for breakfast!
