J2EE 1.4 Tutorial update released
This release of the J2EE Tutorial is for Sun Java System Application Server 8.1 PE 2005Q1. The primary update was a rewrite of the Duke's Bank case study to use container-managed persistence for the entity beans. The previous version used bean-managed persistence.
For those who have wondered about how to use sequential primary keys in CMP beans without breaking CMP's database independence, Duke's Bank now uses a separate CMP bean/db table that retrieves and increments ids when creating other CMP beans. It's still not quite as easy as using sequences in the database itself, but it does the job, and it's fairly simple.
Look for some new advanced JAX-RPC examples in the next Tutorial release.
