Inspite of the poor "track record" of the book , I decided to buy this hoping that I could get something out of it. But it does not cover anything about weblogic. Apart from the fact the book is not about Weblogic , the examples are poor, there are no mention about WEB applications, .war/ear files and gives no useful information. If one want to learn about the J2EE APIs, there are much better books in the market. The one star is for the chapters about security and clustering. One the whole, I wasted time returning it to the post office. I wonder why nobody has sued the authors for giving the wrong title.
