Attributes and Parameters are different..... Parameters only arrive as part of a querystring or in a form post. Attributes are more general, and can be set by the programmer. That said, they are set and read using different methods. several responses to your post suggested using xxx?param=yy or using a forward. Both these will set a parameter that you can read with getParameter.

I guess if i use setAttribute ... i have to use getAttribute ... thats the reason i get the blank string .. coz i was using getParameter my problem is that the jsp uses getParameter ... it would have been good if i could have used the same method regardless as how the parameter was set.
