Sun Microsystems has announced the availability of a preliminary, "qualification" release of Java 2 Platform Enterprise Edition (J2EE) 1.4 source code for J2EE licensees.

The source code provides support for the Web Services Interoperability Organization (WS-I) Basic Profile for building interoperable web services.

Sun had delayed the release of J2EE 1.4 pending availability of the Basic Profile, which was finalised in August. 

The source code includes the J2EE programming model for portable web services applications and also includes compatability tests allowing J2EE licensees to make progress on implementing J2EE 1.4.

A final version of J2EE 1.4 is due later this year. Once J2EE 1.4 is finalised, Sun will release compatability tests, source code and a software development toolkit.

Book Chapters: Mastering EJB 3rd Edition Review Project Much has happened since the second edition of Mastering EJB book series; mainly, the release of EJB 2.1 specification and massive adoption of Web services technologies by the industry. EJB 2.1 had a few but substantial additions in the specification. Besides, EJB 2.1 specification is part of J2EE 1.4 platform, which has some major additions/changes. As a result, a new edition of this book is warranted. The proposed new edition will contain five new chapters - each either covering a major EJB 2.1 technology or focusing on best practices (such as security) related to the same. This plus the normal updates (ranging from 10% to 50%) to all the existing chapters result in an overall 30% change in the proposed edition from the previous one.
