This tutorial covered the basics of writing a simple standalone Hibernate application and a small web application.

If you already feel confident with Hibernate, continue browsing through the reference documentation table of contents for topics you find interesting - most asked are transactional processing (Chapter 11, Transactions And Concurrency), fetch performance (Chapter 19, Improving performance), or the usage of the API (Chapter 10, Working with objects) and the query features (Section 10.4, “Querying”).
