Yet another ADF book - Oracle ADF Real World Developer’s Guide

I'm happy to report that the number of ADF published books is expanding yet again, with this time Oracle's own Jobinesh Purushothaman publishing the Oracle ADF Real World Developer’s Guide.  I can remember the dim dark days when there was but just 1 Oracle book besides the documentation, so today it's great to have what I think might be the 7 or 8th ADF book publicly available, and not to forgot all our other technical docs too.

Jobinesh has even published some extra chapters online that will give you a good taste of what to expect. 

If you're interested in positive reviews, the ADF EMG already has it's first happy customer.

Now to see if I can get Oracle to expense me a copy.

Post edit: Kindly Packt Publishing supplied a copy giving me a chance to review the book.  My review comments follow, also published on Amazon:

As part of my regular job I've read *every* book on ADF. Given there's now several ADF beginners' books I thought the introductory level to ADF area was already amply covered, and I didn't know what Jobinesh's latest ADF text could add. However I must admit I was pleasantly surprised, as even though this book obviously covers many beginners topics, it also covers topics the others haven't making it another valuable addition to the ADF textbooks currently available.

Of particular interest to me was the introduction of:

1) Framework class diagrams - explaining for example how the ADF BC and binding layer classes relate to each other, therefore giving insight into what objects you actually work with programmatically when you drop to code in ADF

2) JSF Servlet, ADF Servlet & Filter lifecycle - a soup-to-nuts discussion starting at the configuration of the web.xml, the importance of the order of the filters, and the overall lifecycle of the framework

3) Application Module scenario diagrams - what objects and methods get called when an Application Module is instantiated so not only do you get an abstract discussion of the AM lifecycle, but how it relates to actual code.

Don't get me wrong, Jobinesh covers all the usual beginner topics, ADF Business Components, task flows, ADF Faces and more, but the fact that he's focused on the Java and Java EE side of ADF brings two very useful discussions on the framework together, which I believe creates a good learning opportunity.

A recommended read for beginners.

ADF Code Guidelines

During Oracle Open World 2012 the ADF Product Management team announced a new OTN website, the ADF Architecture Square.  While OOW represents a great opportunity to let customers know about new and exciting developments, the problem with making announcements during OOW however is customers are bombarded with so many messages that it's easy to miss something important.

So in this blog post I'd like to highlight as part of the ADF Architecture Square website, one of the initial core offerings is a new document entitled ADF Code Guidelines.

Now the title of this document should hopefully make it obvious what the document contains, but what's the purpose of the document, why did Oracle create it?

Personally having worked as an ADF consultant before joining Oracle, one thing I noted amongst ADF customers who had successfully deployed production systems, that they all approached software development in a professional and engineered way, and all of these customers had their own guideline documents on ADF best practices, conventions and recommendations.  These documents designed to be consumed by their own staff to ensure ADF applications were "built right", typically sourced their guidelines from their team's own expert learnings, and the huge amount of ADF technical collateral that is publicly available.  Maybe from manuals and whitepapers, presentations and blog posts, some written by Oracle and some written by independent sources.

Now this is all good and well for the teams that have gone through this effort, gathering all the information and putting it into structured documents, kudos to them.  But for new customers who want to break into the ADF space, who have project pressures to deliver ADF solutions without necessarily working on assembling best practices, creating such a document is understandably (regrettably?) a low priority. 

So in recognising this hurdle, at Oracle we've devised the ADF Code Guidelines.  This document sets out ADF code guidelines, practices and conventions for applications built using ADF Business Components and ADF Faces Rich Client (release 11g and greater).  The guidelines are summarized from a number of Oracle documents and other 3rd party collateral, with the goal of giving developers and development teams a short circuit on producing their own best practices collateral.

The document is not a final production, but a living document that will be extended to cover new information as discovered or as the ADF framework changes.

Readers are encouraged to discuss the guidelines on the ADF EMG and provide constructive feedback to me (Chris Muir) via the ADF EMG Issue Tracker.

We hope you'll find the ADF Code Guidelines useful and look forward to providing updates in the near future.

Another big year for the ADF EMG at OOW12

Oracle Open World 2012 has only just started, but in one way it's just finished!  All the ADF EMG's OOW content is over for another year!

The unique highlight this year for me was the first ever ADF EMG social night held on Saturday, where I finally had the chance to meet so many ADF community members who I've known over the internet, but never met in person.  What?  You didn't get an invite?  Oh well, better luck next year ;-)


Seriously our budget was limited, so in the happy-dictatorship sort of way I had to limit RSVPs to just 40 people.  Hopefully next year we can do something bigger and better for the wider community.

Following directly on from the Saturday social night the ADF EMG ran a full day of sessions at the user group Sunday.  I wont go over the content again, but to say thank you very much to all our presenters and helpers, including Gert Poel, Pitier Gillis, Aino Andriessen, Simon Haslam, Ken Mizuta, Lucas Jellema and the FMW roadshow team, Ronald van Luttikhuizen, Guido Schmutz, Luc Bors, Aino Andriessen and Lonneke Dikmans.

Also special thanks must go to Doug Cockroft and Bambi Price for their time and effort in organizing the ADF EMG room behind the scenes via the APOUC. To be blunt Doug and Bambi really do deserve serious thanks because they had to wear a lot of Oracle politics behind the scenes to get the rooms organized (oh, and deal with me fretting too! ;-).

Finally thanks to all the members and OOW delegates for turning up and supporting the group on the day.  In the end the ADF EMG exists for you, and I hope you found it worthwhile.

Onto 2013 (oh, and the rest of OOW12 ;-) 

Announcing the ADF Architecture Square at OOW12

The ADF product management team are happy to announce at Oracle Open World the publication of the ADF Architecture Square:

Over the last number of years Oracle has recognized that many customers have matured their ADF skills and are now looking for information on advanced concepts beyond the how-do-I-get-this-poplist-to-work type questions.  In order to satisfy this demand we've devised the ADF Architecture Square where papers, presentations and demos will consider such broad software engineering concepts as ADF architecture, development and testing, building and deployment, and infrastructure.  

If you have a look at the site right now it's a rather modest affair, but we hope to continue to expand the content to give further guidance and information to help shortcut your ADF project needs.  Either watch the website or follow our dedicated @adfarchsquare twitter feed.
