what i am doing is i am making a dynamic page on fly using



In jsp file i have huge code in which same parameters are present,
above i made on servlet to save the state of textboxes.

sometime servlet returns NULL, but variable do have value

like ParameterID = 5 in servlet

but when called using REQUEST.GETPARAMETER("ParamID"); on jsp then it takes null.

WHY???

Why do you need a servlet to do that? Not JSP?
