I think you need to go and read about basic HTML form elements
If you actually want to use the form it should be more like:
and instead of that hacky button in an anchor tag, make it an <input type="submit"/>.
That will submit the form to the url specified in the action, along with parameters being the controls nested in the form.
The @RequestMapping annotation is a Spring annotation. You might have better luck in the Spring specific forum than the JSP one.
