Avrom’s Java EE and Oracle ADF Blog

This is an (obviously) late post in a series of posts about ODTUG Kaleidoscope 2009. Monday was the least busy day for me at Kaleidoscope–I only attended two presentations, “That’s Rich! Putting a smile on ADF Faces,” by Lucas Jellema, and “Fusion Design Fundamentals,” by Duncan Mills. But it was perhaps the most thought-provoking of my days there. In fact, I have a full three posts worth of stuff to say about just these two talks. Today, I’m going to talk about a dramatic contrast: the two talks, among other things, represented opposite ends of a debate I consider quite important: the advisability, or lack thereof, of using ADF Faces RC client-side components.

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!

As promised, I’m posting of the presentation I’d been hoping to give at the OOW Unconference Methodology Symposium last week, expanded slightly for the more forgiving medium of a blog. As it turns out, it’s expanded substantially more than I thought, so I’m going to divide it into two parts. This week, I’ll talk about the basics of the methodology, its goals, and the two techniques it relies heavily upon. Next week, I’ll talk about the actual development process it specifies.

“Extreme Reusability” (the name is not mine, but rather Chris Muir’s; however, I decided I like it) is an idea for an ADF development methodology for mid-sized teams (generally around 4-20 developers) that I’ve been recently expanding on. Continue Reading »

Over on the ADF Methodology group, in a thread called ADF Study, we recently talked about ways to get up to speed with ADF. If you’ve been following this blog at all, you’ve probably guessed (from my sheer number of links to them) that I’m a big fan of the various ADF Developer’s Guides. I want to point these guides up a bit, because they’re a massively underused resource, for beginning and even experienced ADF developers.

This is the second part of a two-part series about undocumented tricks with shared application module instances. Last week, I talked about calling methods (at the application module, view object, or view row level) from shared application module instances. This week, I’m going to talk about displaying data (in a non-LOV context) out of them. If you want a general overview of what shared application module instances are and why I think using them is a good idea (particularly at the application scope), look here.
