Checking to see if request.getParameter("myparam") exists

[Steveo]

I'm new to java and JSPs. I was wondering if there is an easy way to
check if a parameter exists. I need to handle the page differently if
the parameter is not there.

Thanks

does it not just return null if it is missing?

if (request.getParameter("name") == null) {
// it's not there
}

I still think request.hasParameter("name") would have been nice to have.
Oh well.
