Look for a book called Professional JSP. Chapter 6 has the best sample MVC code I've seen yet. Used it as the basis for our framework, and we've been very happy.
I've never bought the book and was able to find Chapter 6 online.

This is done with the MVC model using a Controller servlet, beans for communication and JSP pages for display. I have done a basic system that does *part* of this with normal JSP pages that are accessible in the docroot, and the page/servlet communication works fine. Once I'd got that working I tried to apply some access controls by putting all the JSP pages in the WEB-INF directory (for protection - is there any better way?) and routed all pages through the Controller servlet as a virtual path, so any page load is done like this: http://my.url.com/application/Controller/login.jsp and then used the RequestDispatcher to direct them to the appropriate page - no problems there, except the page now has the Controller servlet as the root of all it's references. ie all relative links, images, etc now point to my.url.com/application/Controller/xxx whereas they should (or I would like them to) point to my.url.com/application/xxxx. If the links are changed to absolute paths, the 'application' bit is ignored and so they end up being my.url.com/xxxx, which is not what I want. Obviously, I could fudge it and put /application/images/title.gif (for example) in the JSP page and be done with it, but what if the webapp name changes? I don't want to sit there replacing all the paths. The example is an extremely brief overview of what I mean, but to go into more detail would add another few hundred lines ;) This is one of the many problems I've faced so far in dealing with MVC (which is a new concept to me being a Perl/PHP programmer), but I want to move to Java as my language of choice, and I would benefit greatly from any REAL example of a servlet/bean/JSP web app that: 1. Doesn't use EJB 2. Is at least complex enough to be able to cover most, if not all, of the questions I have about MVC. 3. Isn't some 'framework' to bung into your system. 4. Might be some sort of Java-based opensource web app like phpAds or phpMyAdmin, and use the MVC paradigm. So if anyone has any advice on the above, or has pointers to code, or indeed code themselves, that may help me understand a little more, I'd greatly appreciate it.
