john:
this might help:
Enumeration e = req.getParameterNames();
if (e.hasMoreElements())
{
while (e.hasMoreElements())
{
pname = (String)e.nextElement();
this.put(pname,req.getParameter(pname));
}
}
it cycles through the request parameters and stores the parameter name and
value in a class that extends properties.

Subject: getParameter() != null
Can anyone please tell me how I look for a null value parameter. What I have
is an if loop that iterates through the unknown quantity of parameters(I've
assinged numbers as the names of the parameters). I want to be able to tell
the loop to break when I've come to a null parameter value(hence the last
parameter). I am able to get the value, from the parameter, back as null but
for some reason I can't write a boolean that will return true. I've tried
ALL of the following:
if(req.getParameter(nameOfParam) != null)
if(req.getParameter(nameOfParam) != (null))
if(req.getParameter(nameOfParam) != ("null"))
if(!(req.getParameter(nameOfParam) == null))
String temp = req.getParameter(nameOfParam);
if(temp != null)
if(temp != (null))
if(temp != ("null"))
if(!(temp == null))
NONE of these return true. What the HECK am I doing wrong?
I'd apprecate any help. Thanks
John D. McDonald
