A quick read of the docs for Interface ServletRequest reveal a snippet in
the description of function getParameter :
You should only use this method when you are sure the parameter has only one
value. If the parameter might have more than one value, use
getParameterValues(java.lang.String).
getParameterValues
public java.lang.String[] getParameterValues(java.lang.String name)
Returns an array of String objects containing all of the values the given
request parameter has, or null if the parameter does not exist.
If the parameter has a single value, the array has a length of 1.
Parameters:
name - a String containing the name of the parameter whose value is
requested
Returns:
an array of String objects containing the parameter's values

I only get one, paraname=1, actually I checked 4 boxes, in terms of posted

that is why I have to use HttpUtil, but now it is not working, so where is

It works for me as well. The only caveat is that with text boxes (which I
thought you said you were not using) the browser sends an empty string for
some of the boxes.
Here is some sample JSP code :
HTML
HEAD
/HEAD
BODY

String []vals = request.getParameterValues("foo");
if (vals != null)
{
for (int i = 0; i vals.length; i++)
{
%
LI[%= vals[i] %]/LI

}
}
%
BRHR

INPUT TYPE="checkbox" name="foo" VALUE="Bar2"Foo/INPUT

Re: HttpUtil
Hmmm... you can always try to look at the source code for parsePostData()... that is the beauty of open-source.

Re: HttpUtil
I read it, suspect problem is on webserver or tomcat, they cann't handle inputstream well, but how to resolve it? what is real problem? am I right to say "short read" is inputstream's error? -Original Message- From: Chris Janicki [EMAIL PROTECTED] To: [EMAIL PROTECTED] [EMAIL PROTECTED] Date: Sunday, February 11, 2001 10:02 PM Subject: Re: HttpUtil Hmmm... you can always try to look at the source code for parsePostData()... that is the beauty of open-source.
