ok, in PHP there is a command called isset(). It returns a boolean to
tell you if a certain variable was passed to the program or not. (Helps
eliminate those nullpointer exceptions without putting everything in
try/catch statements) Now, I was looking for one in JSP and I'm having a
little trouble. I think it may just be I don't know what I'm looking
for, so if anyone would be so kind as to let me know the name of the
function if it exists it'd be MUCH appreciated. Thank you in advance.
