We all loved the JPA ever since it came ot in early 2000s. In combination with EJB 3.0 spec, the programming was a lot easier and fun.
Then came the boom in web 2.0, mobile applications, social applications. Applications become huge and while once the developer was an expensive resource, tables have turned and with the systems getting larger and larger, frameworks like JPA, EJB have become more expensive to run. Even because these technologies were so cpu intensive, no one ever ddared to run on mobile platforms like Android.
Fortunately, there is now Batoo JPA, the new smart kid on the block. Batoo JPA is built on top of JPA 2.0 spec and with the performance being the top priority.
We wish fellow Enterprise and Mobile Java architects and developers to give it a try. You may find Batoo JPA at http://batoo.jp.
