The Next JDeveloper Patch Set

So, if I’ve timed this right, the next JDeveloper Patch Set will have been announcedby the time  this blog post goes up, so I should be able to talk about it.

There’s a new minor release of JDeveloper that’s targeted for some time in the next few months. Here’s a partial preview of its features: Continue reading The Next JDeveloper Patch Set

The JDeveloper 11g Handbook is Here!

The JDeveloper 11g Handbook: A Guide to Oracle Fusion Web Development is being released today! If you’re at Oracle OpenWorld, you can pick it up at the conference bookstore starting Monday. If not, you can buy it from Amazon.

You can access errata, database scripts you need for the hands-on practices, and hands-on practice solutions from the TUHRA2 home page on samplecode.oracle.com. Pretty soon you’ll be able to download code snippets from there, too.

Design Patterns and You: The Bridge

In the spirit of the last post, I want to talk about another design pattern that’s useful in a wide range of Java development cases, and for which I think better tooling support (maybe in the form of a JDeveloper addin!) would be very useful: The bridge, also known as the driver. You’re probably familiar with the term “driver,” at least in the sense of device or JDBC drivers, and as we’ll see, there’s a reason why the driver pattern shares a name with them.

The stated purpose of this pattern is to “decouple an abstraction from its implementation so that the two can vary independently.” This may not make much sense at first, so we’ll start with a concrete example.

Vote for my Oracle OpenWorld Presentation on Oracle Mix

So, I submitted a presentation, “The Rich Get Richer: Ultimate RIA with Oracle ADF Faces RC Client-Side Objects” to Oracle OpenWorld 2009, in San Francisco this October. The presentation is about performing tasks that usually require a partial round-trip, such as cascading dropdowns, conditionally visible content, etc., with no server round-trip at all. I talk a bit about this, on a very theoretical level, here (in the section, “Consider a Javascript-Only Solution,”) but I plan to go into considerably more detail, giving practical examples and advice, in the presentation.

The presentation did not make the cut of abstracts selected by Oracle. But if you want to see it at OOW, there’s still a chance! Just vote for the presentation on Oracle Mix (you’ll need to create an Oracle Mix account if you don’t already have one, but it’s free and a good way to meet people in the ADF community).

See you at ODTUG and/or OOW!

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!
