Roman Strobl has created an excellent 7 minute screencast of how to use NetBeans and the JPA (Java Persistence API) to build data-aware applications at the flip of a switch. It's really impressive what you can build by entering a JDBC URL and clicking a few buttons - full-fledged applications that are easily customized. Similar support is available for the JSR-311 REST API, Ruby on Rails, and Grails.
