For years, the Enterprise JavaBeans(tm) (EJB(tm)) and Java(tm) Data Objects (JDO) specifications have evolved independently as they addressed different sets of requirements. The core of both specifications, however, includes persistence technology. Even to this day, the data persistence models in EJB and JDO differ significantly. This divergence has caused confusion and debates among Java developers, and is not in the best interest of the Java community. Consequently, requests to put an end to this unwanted divide have poured in from members of the Java community. In response to these requests, Sun Microsystems is leading a community effort to create a single POJO (Plain Old Java Object) persistence model for the Java community. This effort will strengthen community solidarity.
