Multiple submit sources delegated to only one method

[pedrodx]

Hi! I'm working with JSP / JSTL, and I have a form that has multiple submit sources, i. e. 4 submit buttons and one dropdown that submits the form.
The form is submitted to a method of a Spring MultiActionController, and what I want to do is discover what is the source of the request, WITHOUT using request.getParameter("name")... I think I was told not to do that... Is there a more ellegant way to do this?? Thanks in advance!!!

Why not have each button submit to different methods then call the common method they all need to eventually access?

void submit() {
// do some code here that's common to all submit methods.
}

void submitA() {
// log something
submit();
}

void submitB() {
// log something
submit();
}

etc...
