Hi I have deployed a jsp application on WAS 6 server. My application as a refresh button, which internally on click calls servlet and passes some parameters appended. But some times it behaves strangly. It is missing some parameters. And opens a save dialog box. But I am not facing same problem in WAS 5 server. Can you help me in debugging this problem. I think it is problem with WAS6 web container. AM I correct in saying that and if so what is solution.
