TheServerSide.com have a book review of a book called ‘Covert Java’, which covers topics such as decompilation, JVM internals, debugging, and tracing.
These are topics which are not covered in many other books – some good reading for someone with a couple of years Java experience and wants to increase their understanding of the Java platform, although maybe not as much use for someone with more than a couple of years experience and has probably already used these techniques.
Bruce Tate makes an amusing analogy between the EJB spec and hunting elephants in this article.
Good comments here about how early adopters felt forced (and still do?) to take on all that the EJB spec offered, even though it was probably not the best fitting solution.
This article on TheServerSide.com discusses the recent announcents regarding EJB3.0 changes and support for POJO persistence, and also the big players voting down the JSR for JDO2.0, due to overlap with ‘other interests’, namely at the time the upcoming EJB3.0 recommentdations.
