Thanks for your response Pat. But i am thinking to go with SmartGWT
because whatever i read about SmartGWT it seems to be no memory
leakage in this API.

But i want to know also, is there any solution with embed GWT , GWT
EXT in JSP? Yesterday when i talked with one of my friend then he was
telling me may be if you are doing like this then JSP will take care
of DOM references. but when i R&D on google about this way, i not
found even a single hint on this JSP + GWT.

Thanks and regards,

Sunil Bansal.
