Apple, JavaOne and Oracle
MacWorld.co.uk has an great article about Apple's commitment to Java technolgies at the JavaOne conference:
We want to encourage developers at the conference to bring their applications to OS X. To support this, Apple is offering a compatibility lab of 10-15 Macs, fully staffed to help developers get their applications to Macintosh during the show.
The article also mentions that Apple is working with Oracle to move its (presumably, Java) applications to OS X:
Were working with Oracle on bringing its applications to be fully served by OS X and were trying to do this as soon as possible
