Also, If you have any information about declaring a variable with !
I would like to know. I am having trouble finding any on google and
my JSP book.

I started to look in the _jspService and I noticed the the variable
which I assign the request.getParameter("id") to is not in that
method.
The variable is called 'theID'. One thing I noticed about it is it is
declared like this
!String theID;
I have never seen this before. Does this make the variable static?
If so then it is obvious why this is happening
I am going to look up this ! operator to see what it does. I 3 years I
have never encountered it. Hopefully removing it will solve my
problem. I will keep you updated.
