Business logic layer - what to use?

[Matthew Carpenter]

One well-accepted way of handling business logic is to use Java.  There 
is a great deal of middleware architecture to aid in this, namely J2EE. 
 However, if you are simply interested in writing ground-up code, the 
J2SE (Standard Edition) works great.  This is how all my middleware is 
written, specifically for my web-apps, but GUI apps work great with this 
approach as well (even if Java isn't the GUI client).

Keep us informed.
