My advice.

Use concrete class with the business tier, and interfaces that defines the
available services.

Now if you want to use any framework, use decorators (GoF pattern) to adapt
them. And use a IoC container (Spring, Avalon, etc) to hide the lookup

Like that you can use EJB, Commons Commands, RMI, or anything you want
without changing the iner working of your main implementation.

Subject: Business Tier


I am trying to decide what utilities/frameworks to use for the Business Tier
and was wandering if anyone had good suggestions.  Looking at Struts in
Action book the Scaffolding classes are mentioned frequently and are used in
the sample Artimus app.  I tried looking at these but wasn't sure if this is
an old utility.  Also it would be useful to know of any decent utilities to
run queries an stored procedures as opposed to using the JDBC interface

Any advice would be useful

Many Thanks
