In a letter to the “Java Technology Community” on Friday, specification leads on Java Specification Request (JSR) 220, which is the proposal for Enterprise JavaBeans 3.0, and JSR-243, for Java Data Objects, state that the two technologies feature divergent persistence models. “This divergence has caused confusion and debates among Java developers, and is not in the best of interest of the Java community,” said JSR-220 leader Linda DeMichiel who also is a Sun employee, and Craig Russell, a staff engineer at Sun who leads JSR-243.
“In response to these requests [for an end to the unwanted divide], Sun Microsystems is leading a community effort to create a single POJO (Plain Old Java Object) persistence model for the Java community,” the letter said. POJO will serve as a temporary name for the model until a permanent one is devised.
