request.getParameter

[dennisGuru]

Hello,

I have a jsp page with several buttons.
<INPUT TYPE=&quot;submit&quot; NAME=&quot;button_A&quot; VALUE=&quot;Goto A&quot;>. I use these buttons to go to another page, depending on wich button is used.

In the servlet I retreive these with req.getParameter(&quot;button_A&quot.

Once a button is clicked the value stays in the request/session. Is there a way to remove this. I have tried it with session.removeAttribute, but this doesn't work. Also setting the variables to null did not help.

Thanks in advance.

Dennis

Well, you can remove an object from the HttpServletRequest by calling HttpServletRequest.removeAttribute() - but I cannot see the problem as HttpServletRequest parameters are not HttpSession objects, and only persist as long as the request is being handled ...

I have looked for this method, but could not found it. I have looked in the wrong place. Thanks alot. It worked.
