Actually i want to use the textbox value and set the session parameter in the same JSP page without submitting it or like using request or response object. This textbox value i want to use in the same JSP page for further use. How can i access the value of a text box in the same page?
You could either utilize the new HTML5 local storage (only supported in the more recent/modern browsers), or you could create a session cookie in JavaScript and store the value in there.
Note that none of those approaches will affect the server side
HttpSessionin any way. For that you simply can’t go around sending a HTTP request containing the desired information, as that’s the only way to send information from the client to server side. You could however consider using ajax to send the HTTP request asynchronously and fully transparently in the background.
