Framework for Package-Based ADF BC, My ODTUG Schedule, and More

Like the poltergeists, I’m baaack. I’m back to my usual health, and while I’m still pretty horribly snowed under, I think that enough of the worst of it is over that I can generally commit to my “Updates Mondays” schedule again. This has been a *long* hiatus (over 6 motnths), and I’m very glad to be back among the lang of the living. I’ve missed this blog and the ADF community generally.

Although I plan to get back to the ADF BC Tuning series soon, I want to use this post to announce two things: The first piece of software I’m releasing on this site and my public (that is, not just as an audience member) at ODTUG Kaleidoscope, which will be next week in Monterey, CA.

First, the software. This is actually related to one of the talks I’ll be giving at ODTUG, and tangentially related to another. But even if you aren’t going to the conference, I hope you’ll find it useful. It’s an extension of the ADF BC framework that allows you to create the following 100% declaratively:

  • Entity object definitions (including support for optimistic or pessimistic locking and Refresh After… settings) that use Package APIs instead of DML
  • View object definitions (whether entity-based or not, and including support for query parameters) that use Package APIs instead of SELECT statements
  • Associations and view link definitions involving the above

You can get the framework here.

At ODTUG, I’ll  be participating in the following:

Hope to see you there!

The Power of Properties

Most ADF BC users are traditional Oracle developers–Forms or PL/SQL developers–who are relatively new to Java and Java EE (some, at this point, have lots of Java expertise, but even those usually have still more experience with an older Oracle technology). Because of this, when they miss out on one of the greatest powers of Java, reusability, they often don’t realize, or at least appreciate, what they’re missing out on. So the fact that ADF BC doesn’t openly encourage designing custom code for reusability gets missed.

But this is emphatically not to say that ADF BC doesn’t enable reusability, or even that it’s not documented. It’s just not called out in ways that would encourage a novice, or even intermediate, ADF BC developer to take advantage of it. Continue reading The Power of Properties
