Dynamically loading the jsp page to the application

hi i am building a application and in that application the user should be able to create forms with the form elements he wants i.e a normal form which we fill to apply for anything.
I would like to know how can i do this.He should be able to get the values that are entered in the form.

simple....use <form action="somefile.jsp" method="post">
use form elements
</form
in somefile.jsp
use request.getParameter(String)

will the user be able to create form himself that is add text box,check box etc .. to the page

most probably u need AJAX for this...
