1) Sun provides a Java EE server implementation, aka Glassfish but none enterprise-scale database engine;
2) Oracle provides an enterprise-scale database engine, but none Java EE server implementation;
3) Things between Oracle and RedHat have been spicin’ up because of Linux distrowars, so Oracle, IMHO wouldn’t even try to acquire JBoss.
So, what happens?! ..oh well, pretty obvious, don’t you think?
