your are accessing Login bean through jsp:usebean direcive
and your trying to call validate() function of login bean which is not exist.
Add validate function toyour login class or try to call existed function.

A few things to help you get answers an JavaRanch:

Firstly, please use real words when posting to the forums. Abbreviations such as "pgm" in place of "program" only serve to make your posts more difficult to read and less likely to generate useful responses. Please read this for more information.

Secondly, please avoid posting in all uppercase. It's considered shouting and rude. Please read this for more information. I have adjusted the topic title for you.

And lastly, please be sure to take the time to compose descriptive subjects for your posts; read this for more information.

Using a title of "problem with jsp" in a forum completely dedicated to questions on JSP isn't very helpful.

Please go back and change your post to add a more meaningful subject by clicking the .

It is sorta covered in the JavaRanch Style Guide.
