What do you mean by "when I trie to read the values"?
How are you reading the values?

Are you posting an HTML form to the servlet and retrieving the values with the request.getParameter function?

If you're having trouble explaining what you're doing, post the code.

Hi when ou want to read a value from jsp to servlet you need to use request.getParameter().

e.g if you have a textbox in jsp with a name "id", you should use request.getParameter("id") in the servlet. Remember, the name in jsp should match the string in the request.getParameter() function.

Hope this helps
