Volume 1 of this advanced 3-volume guide explores the infrastructure issues so important to

good application design. It isn't just a book about Entity Beans and JNDI. It takes you step by

step through building the back end, designing the data store so that it gives you convenient

access to the data your application needs; designing a directory; figuring out how to handle

security and where to store security credentials you need; and so on.
