This week I saw an announcement on Ajaxian that several high powered engineers were leaving Sun Microsystems for JackBe. I recognized all of the names of the engineers from the influential Core J2EE Patterns book that they collectively co-authored.
Unfortunately, visiting the JackBe web site does not give a very good first impression, particularly the large-ish advert that might as well read “make your company fully buzzword compliant with our Ajax assessment!!”. This reminds me of around 8-10 years ago when every consulting company was offering a ‘Java assessment’ or ‘Java Jumpstart’ and how such things will give you a ‘technical/competitive advantage’ to anyone who would take the bait. Repeat the same for client-server, object-oriented programming, eCommerce, agile programming, INSERT_YOUR_FAVORITE_HERE.
This is not to say that Ajax does not have value (it does, when applied appropriately), but it is to say that anything can be oversold.
