The query string is ONLY the parameters passed on the URL after the ?,
these can appear on both a GET and a POST (though for POST it would have
to be in the action URL itself, not a form parameter).
If you want the list of parameters from form fields on a POST, you can get
them via request.getInputStream(). Normally they are encoded in the same
way as the query string (unless you change the enctype on the form).
This isn't a bug.

Subject: Bug in HttpServletRequest.getQueryString()? from POST
Hi when processing a request in a tag extension class I get a "null"
returned when I call HttpServletRequest.getQueryString() after a POST
when I change the form to use GET, I
get the QueryString as expected. my code fragment looks like:
public int doStartTag( )
throws JspTagException
{
try
{
previous = start - count;
if ( previous < 0 )
{
previous = 0;
}
out.print( "<a href="+nextPage+"?startAmbiguity="+previous );
//
// WHY does getQueryString() return null from POST?
//
out.print( "&"+((HttpServletRequest)pageContext.getRequest(
)).getQueryString( ) );
out.print( ">"+title+"</a>" );
return SKIP_BODY;
}
catch ( IOException ex )
{
throw new JspTagException( ex.toString( ) );
}
}
The query string contains information which I don't particularily
displayed in a GET URL, so how do I work around this, apart from getting
all the parameters and building the query string myself?
