We are actually quite busy in all areas above:
Database independence - we started implementing an OMG based workflow engine. This will allow us to do the transaction control in Java and convert the PL/SQL to Java.
We'll discontinue the JBoss specific functionality (MBeans) and convert it to standard J2EE technology.
We'll convert to Java Faces, which produces a bit better HTML UI and is browser independent.
All that requires real work and a commitment for more than an hour per day and actually quite a few years experience with complex systems. It's not easy to contribute to a full featured business application, but the ones who do are able to deliver supreme benefits to their (paying) customers.
