Professional to Expert? Only an overview on the j2ee.I am wondering about the contents of the "beginner to professional" book...Give it a try if u want to have a light explanation on j2ee key tecs.Example: the chapter Using EJB Container Services starts from page 621 and ends at page 653. Everyone knows that arguments like Security services, Transaction Services, Scheduling, Instance pooling and caching worth more than 30 pages...J2EE bible is still the best tutorial/reference for a professional.
