I'd suggest that any Java code puts either in Tag Extensions or
servlets. Going even a little further, try to follow Model 2 ideas.
Create *one* servlet controller which controls who should do what. In
that case, all JSPs do is only to display beans' state.
To answer your question(s), just put it inside servlet controller, so
the following JSP pages can use it. After that, just forward request to
JSP to display it. When you becomes more familiar with that approach,
you won't have to search all your code, just to check out whether
everything is right. All you'll have to do is to open *one* servlet
controller and modify it as you wish.
Simple ? Yes, it should be:)
