I know you don't want to hear this but I'm not sure about what I can
release due to company restrictions. I wouldn't want to get fired for
posting out source. I will ask the right people if I can post a few
pages of the source but it may take a while for them to get back to
me.
I haven't found any docs but I think the ! operator makes the variable
a member of the class, not the _jspService method.
When I search for the declaration of 'theId' it was declared as a
member of the showCa_jsp class with no modifier (default). I am
assuming that tomcat will create once instance of this class, and use
it when ever that page is requested. The _jspService variables will
be different for each instance since they are local to that method but
the member variables will be shared.
I can't find the doc on the operator for JSP. I think this is the
problem but I want to be sure that it is before I remove it from the
code.
