Hi Frank, If you look at the link I provided you can see we had a pretty large project. I was working with a team working in multiple places in world. Maintaining and synchronizing struts-config.xml file did give us some bad time at beginning. So we choose the spirit of struts, MVC, but avoided this problem. We are working on an even larger project, so I had this question.
>From beginning, I know performance was not a problem (see my previous posts). Maintenance was. For programming example, we like large C program becomes smaller pieces so application can be more managable. When struts becomes more mature and solve larger and more complex problems, we certainly may find some problems. That is the reason I propose this question. (I had some bad experience using a struts-based large web system. It was easy to see if a system was struts based if its URL showed something.do?) Hi Craig, Thank you for the link of Struts Console program. It looks better than the XML editor I used for struts before. Struts is a nice system. ----- Original Message ----- From: "Frank W.
