Is it possible to retrieve the form name from a Ja

问题:

I would like to get the name of the form used to post parameters from a Java HTTPServletRequest object. Is this possible. I don't see any method that looks like it will return it to me.

HTML form name is NOT submitted as part of the request. If you need it (why?) you can submit it as hidden input instead:

<form name="myForm" action="/my_servlet">
  <input type="hidden" name="htmlFormName" value="myForm"/>
  ...

In your servlet:

String htmlFormName = request.getParameterValue("htmlFormName");
