So I was preparing the data for this website locally on my machine. My staging environment was pretty much the same (same Java VM, JBoss AS, MySQL version, etc.) The only difference is the operating system, it's OS X and the live site is running on CentOS. I created a package to deploy and everything looked fine. Until I edited documents on the live site. MySQL started to throw constraint violation errors it didn't show in the staging environment.
Happy Birthday Hibernate! Now that the first copies of Java Persistence with Hibernate are shipping (still waiting for mine though), the first people who should get one are Hibernate contributors. Manning Publications sponsors 25 copies of the book, and we'll distribute them in exchange for 25 Hibernate forum credits. See this page for details.
At JBoss World last week in Berlin I presented some advanced Hibernate patterns. Well, I planned to talk longer about the Swing and Hibernate demo app I wrote a few days before but it turned out that although 100% of the audience was using Hibernate, only one poor soul had to work with Hibernate in a two-tier desktop application scenario. So I spent more time on the other patterns and only showed the Swing demo for about 5 minutes at the end of the presentation.
After an extensive and quite challenging editing period, the 880 pages update to /Hibernate in Action/ is now available. You can get the eBook on the Manning website. The book is currently being printed and should soon (I guess in about two weeks) be shipped to all MEAP subscribers and resellers such as Amazon.
