Subject RE: Variable

It's probably better to not do this in a declaration, like this:

   <%! int var = 0; %>

But instead, use a scriptlet, like this:

   <% int var = 0; %>

A declaration (as the O'Reilly JSP book describes) ends up being "an
instance variable in the JSP page implementation class.  It us therefore
visible to parallel threads (requests) processing the page, and needs to be
handled in a thread-safe manner.  A thread-safe alternative is to declare
variables within a scriplet element instead.  It then becomes a local
variable of the method in the page implementation class used to process each
request, and is not shared by parallel threads."
