NetBeans Wiki: Best Practices With JPA And BeansBinding

A great technical guide on the NetBeans Wiki which quickly and clearly goes through how to use beans binding with JPA, including the question that comes up all the time: how to use the Beans Binding support with Java DB embedded.

People get very confused because they see the tables and data in the Database Explorer but they aren't there when they run their app. And I quote: "Don't be confused if you don't see the data (or even tables) when you run your application in spite of the fact that you can see them in Services window of NetBeans. Recall that Derby is looking for the DB in the working directory and the working directory of NetBeans is different from the working directory of your project."
