Avrom’s Java EE and Oracle ADF Blog

A bit of news about my next book:

• We finally have a fixed title: Oracle JDeveloper 11g Hanbook: A Guide to Oracle Fusion Web Development.
• We’re planning to ship to the printers by August 24th–less than a month from now!
• The (very serious) plan is that we’ll be on the shelves by October 12–in time for Oracle OpenWorld 2009!
• Although we started writing a long time ago, we’ve checked everything against the most recent (July) release of JDeveloper.

I’m really excited about this book; I think it will be a substantial step up from the last two handbooks in terms of scope and detail.

This week’s post is going to be late again, and it’s not going to be another ADF BC Tuning post. It will, however, be some news about the JDeveloper 11g Handbook.

Last week, I talked about the essentials for doing any client-side component manipulation, as described in Lucas Jellema’s ODTUG Kaleidoscope 2009 talk, “That’s Rich! Putting a smile on ADF Faces.” This week, I’m going to talk about a couple of simple use cases for client-side programming that he demonstrated.

Before I do that, though, I should mention what I think is currently the most important resource for client-side programming: Frank Nimphius‘ JavaScript Programming Nuggets page. That contains a lot of tips about ADF Faces RC client-side programming, and goes into a considerably higher level of sophistication than Lucas’ talk did (or this post will). But in case you find that a bit intimidating to start out with, here are three very simple use cases for client-side programming.

It’ll be up within a few days.

Two weeks ago, I compared a pair of talks I saw at ODTUG Kaleidoscope 2009, “That’s Rich! Putting a smile on ADF Faces,” by Lucas Jellema, and “Fusion Design Fundamentals,” by Duncan Mills. In particular, I contrasted the two opinions given of ADF Faces RC client-side (that is, Javascript) programming, and came down on Lucas’ side: Adding Javascript to ADF Faces RC applications, though it shouldn’t be overdone, can be very useful, and the usual risks attendant on Javascript programming are significantly mitigated if you develop exclusively to the ADF Faces RC Client-Side API (rather than attempting direct access to/manipulation of the DOM) and understand what validation in Javascript can and can’t do (provide convenience for the user and protection against honest user error and provide real enforcement of data integrity, respectively).

What I didn’t get a chance to do in that post was talk about the actual tips for client-side component manipulation that Lucas provided. I’m going to do this over the next couple of weeks. This week, I’m going to talk about the essentials for doing any client-side component manipulation. Next week, I’ll talk about some specific component manipulation use cases that Lucas went over in his talk.
