Thanks for building the application. I'm very curious to take a
look at it.

Great, I look forward to hearing your thoughts, comments, and criticisms.

At this time, I have an odd question. How is the code in the jspf
file used? I see that it is used to determine what type of AggregatorDAO
to use, but I'm not sure how actual Java code is used, so I'm very
curious. I've always used a properties file for this type of thing
where the class type is grabbed by a Broker object to take a separate
path through the app to hand out the proper DAO type. Please explain
how the jspf file contents are used.

That setup.jspf file is just a JSP fragment that is included in my other JSP pages, it is responsible for creating the DAO implementation and putting it into the web application context. This is not a best practice.

It would be much better to do what you suggested, use a property file or a Servlet Context parameter to specify which DAO implementation class is to be used. Right now the only way to switch from Hibernate to Castor is to edit that setup.jspf file.

Thanks,
Bruce
