Java Servlet problem: radio button with no default value won't be picked up by "HttpServletRequ

[Allan Huang]

Hi,

We are using a generic Java Servlet to process various submitted form using
codes similar to what's shown below. The problem is, radio buttons with no
default value won't be picked up by "HttpServletRequest.getParameterNames".

Any idea why or any way to work around that?

Cheers
Allan


public void doGet(HttpServletRequest request, HttpServletReqponse response)
{

.....

Enumeration paramNames = request.getParameterNames();
while (paramNames.hasMoreElements()){
String pramName = (String)paramNames.nextElement();
......
}
