This week's book giveaway is in the Other Open Source APIs forum. We're giving away four copies of Storm Applied and have Sean Allen, Peter Pathirana & Matthew Jankowski on-line! See this thread for details.
The process of transferring data between a relational database and Java objects is the same regardless of what type of application you're writing. If you're not familiar with how JDBC works, I'd suggest you spend some time with some JDBC tutorials such as this one. Once you learn this process, you can simply plug the JDBC code into your Struts application. For example, if you wanted to make the example you've mentioned above use a real Database rather than just static variables, write some JDBC code and plug it into the IndexedBusinessLayer class and the rest of the example will work as-is.

Then it does not seem like it would be too hard to translate the code into update queries. Are you just trying to get the example working with a database or are you trying to apply the concepts to your real application?

It's one thing to be able to write SQL statements. It's another to be able to use them within the context of the JDBC API. If you don't already know how to use this API, you'll need to learn it before going any further. Here's a brief example:
