The default behavior for a submit button in an HTML form is to send a
request for the URI specified by the form's action attribute (with all
the values entered in the form fields as parameters). So if you specify
a JSP page as the action, the JSP page will be executed by the web
server.
If you, however, want to exeute some code in the browser *before* the request
is sent to the web server (or instead of), you need to use JavaScript code.
Keep in mind what type of code executes where: code in a JSP page is executed
on the server when the page is requested, JavaScript executes in the browser,
triggered by some user interface event such as a button being clicked. Pick
the technology that meets your application demands for each task.
