I am trying to determine if a page was called with a parameter or not,
and display output based on this, however, java is complaining about a
NullPointerException,
here is what I am trying to do:
// Did we get called with a machine name?
boolean machine=true;
if (req.getParameter("hname")==null)
machine=false;
if (machine) {
// blah blah big table
}
else {
// blah blah a different table
}
when I use getParameter the url ~/update.jhtml?hname=something works
but ~/update.jhtml does not.
Conversely, when I use getParameterValues the url ~/update.jhtml
works, but ~/update.jhtml?hname=something does not..
the error looks like:
!-- java.lang.NullPointerException
