I'm doing a session about Fusion development with JDeveloper and ADF in the North California Oracle User Group meeting tomorrow in Pleasanton.
This will be relevant to you whether you are a Siebel, Peoplesoft, E-Business Suite or just a simple Java/Enterprise developer.
I'll be showing both the current JDeveloper as well as some of the key features of the upcoming 11 release.
I also noticed that Peter Koletzke is doing a couple of other JDeveloper related sessions - so plenty to see if you are currently a JDeveloper user as well. Hope to see you there.
