I'm not an Oracle developer. I'm not an Oracle DB Manager. I'm not an Oracle Java Developer. I'm an Eclipse lover since Eclipse 3.0M* releases but, because of the power of Oracle, I had ever followed our development in the Java-Development-World.
5 days ago I Oracle sent to me information the release of JDeveloper 10.3 and OC4J 10.3 (Oracle Container for Java - our Application Server), and today I spent a little amount of time looking at the new features of JDeveloper and looking the interesting flash-screencast-demos.
Obviously, these product are available for Linux, Windows, MacOSX and... any Java-Enabled systems.
And, if you don't know it, Oracle is an Eclipse Add-In Provider and it's not impossible to have a plugin Eclipse produced directly from Oracle.
Update: Oracle's ADF Faces donation to Apache. Oracle is not completelly indifferent respect the OpenSource. It's not?
