JDeveloper/ADF News from Oracle OpenWorld 2008

This week I'm in San Francisco, attending Oracle OpenWorld 2008 conference.

One of the main news for me, announced on Ted Farrell keynote - Breaking Enterprise Application Platform Barriers, was a date of JDeveloper 11g production release - October 1. I already can start to play with it, Oracle provided private ACE Directors build on September 21.

Ted Farrell announced Oracle Developer Tools Strategy:


As you see, JDeveloper/ADF is Oracle's strategic tool and framework. Enterprise Pack for Eclipse is second strategic tool, designed for core Java developers.

On the same keynote, vision for Rich Enterprise Applications powered by ADF and WebCenter was defined:


In 11g, ADF becomes really rich framework, with support for WebCenter Services, View layer with JSF Core, Data Visualization, GeoMap and Data Manipulation. ADF can render View layer on different devices, in the future there will be support for iPhone as well.

I already did my session on Monday - My Session at Oracle Open World 2008 (Oracle Develop). It was attended very well, almost full room (60 people), and what is most important no errors in demo development. You can download application - OraMaps11_Session.zip, I have developed during my session:

Oracle ACE Office Hours in the OTN Lounge

Today I got email from Oracle people about Oracle ACE "Office Hours" activity in the OTN Lounge during Oracle OpenWorld 2008.

Main idea of those "Office Hours" is to create opportunity for Oracle ACE's and Oracle ACE Directors to meet with conference participants and to answer possible questions.

I will be on duty after lunch on Monday, September 22 and will be happy to discuss daily things related to JDeveloper/ADF development, and not only...

See you there !

ADF Methodology For The Masses on OOW'08

Good news for all JDeveloper/ADF developers - ADF development methodology is in the process, Oracle community is defining it and it'll be available soon. You can track our progress on Oracle Wiki page - ADF Methodology. I believe this methodology will help a lot in daily life, since it will be good reference with descriptions how things should be done in JDeveloper/ADF.

I know its always fun to develop prototypes, but when you in real project, usually you need to have some standard about how to structure application packages, how to define names for components in Model and ViewController layers, and how to find meaningful names for navigation links in application Task Flow. Other important area - reusability. Developers always should reuse code, however how its to do better in ADF, will be described in ADF Methodology. Everyone is free to suggest topics for ADF Methodology, just visit our page on Oracle Wiki.

If you will be on OOW'08, you can register here and attend workshop dedicated to ADF Methodology. Also, you can see how work is progressing on Google Groups - here.

I hope ADF Methodology For The Masses will be same cool as songs from Depeche Mode album - Music For The Masses :-)

See you there in San Francisco !

Oracle Open World 2008 - Abstract Accepted

I have very exciting news - my abstract for Oracle Open World 2008 session is accepted by Oracle and I will represent Vgo Software on this event. I will be presenting on the following topic - "Oracle Maps in JDeveloper 11g - Perfect Combination".

Actually, it was extremely good news for me, since there was only 5 (2.5 for Database and 2.5 for FMW) free slots available for Oracle ACE Directors submitted abstracts. So, I'm really happy, to take 1 slot from 2.5 available :-)

You can read about Oracle Maps combination with JDeveloper in my previous blog posts. I will provide detailed information about my presentation more close to the event.

Oracle JDeveloper/ADF Real Life Story on Oracle OpenWorld

Yes, that right - I was presenting Oracle JDeveloper/ADF Real Life Story on Oracle OpenWorld in Unconference section. Everyone was free to come and listen hints I have delivered for Oracle JDeveloper/ADF development based on real life experience. Based on feedback received from auditory, I think session was successful.

I have started session with presentation based on this outline:

• About Oracle ACE Directors
• J2EE Development - JDeveloper 11g and Oracle ADF (future book)
• Oracle JDeveloper/ADF in IBM GBS Norway
• Real Development with JDeveloper/ADF
• Demo of Sample Applications from http://andrejusb.blogpost.com
• Technical Resources
  

Yes, I'm writing now book about JDeveloper 11g and ADF. This book will based mostly on practical material. I have presented with several slides my current project in IBM GBS Norway and turned to main part of session - Real Development. In this part I was developing Web application with JDeveloper and ADF just on the fly, at the from of auditory. Application development from beginning to testing took for me 45 minutes. And lastly I presented my blog and have talked about technical resources each JDeveloper/ADF developer should know and use in his daily work.

In this post I want to concentrate on application I have developed during real time development. Developed application - OOWUnconference.zip is based on standard HR schema available in Oracle XE database, application contains 3 Web pages - for viewing and editing data from JOBS table, and also for viewing data from EMPLOYEES table.

I have developed this application based on those steps:

1. I created Business Components diagram. I was using declarative approach to create Model layer. Jobs and Employees entities were added to the Model declaration:


2. Second step was to show how test created Model layer with ADF BC Test utility that comes with JDeveloper:


3. Next step was to show how to add validation logic. Jobs entity object was chosen, I added and tested validation rule for MinSalary attribute:


4. When Model layer was done, I moved to ViewController and have created there page structure along with navigation:


5. First page I developed was - jobs.jspx. This page contains one read-only table and two buttons according to logic defined in faces-config.xml file.


6. Second page was editJob.jspx. This page provides a form for data from Jobs entity editing:


7. Third page - employees.jspx. Here employees who belong to specified job are listed in the table:


8. And of course I have tested validation logic in editJob.jspx page, it worked good:

However, there was a question from auditory about how to make Back button work in a case when validation error is displayed. Hint - you should set Immediate=true for Back button:


9. Ok, everything works fine, but one thing is not ok. If you have noticed, it is possible to update minimal salary with some value, even higher comparing to salaries of existing employees. That not good, and I have implemented solution for this as well. At first, I have created new read-only View object that select all employees with selected JOB_ID and SALARY lower comparing to provided value:


10. When View object was created, I implemented custom method in Application Module. This method is used to execute read-only View object and to return result to ViewController:


11. In ViewController I have created methodAction declaration for checkEmployeeSalary method and in editJob page backing bean implemented a call to defined methodAction:


12. Now second validation rule is also implemented:


Oracle OpenWorld was great event, with two Larry Ellison keynotes and a lot of technical material in Oracle Develop. I even don't talk about entertainment part, it was amazing. See you next year in San Francisco ;-).

When running sample application, don't forget to add adf-faces-impl.jar and jsf-impl.jar to application's WEB-INF\lib directory.

Oracle OpenWorld Unconference - Session Proposal

I'm planning to do a session at Oracle OpenWorld Unconference. Session is called - Oracle JDeveloper/ADF Real Life Story, more info and it's description you can find on Oracle Wiki page. Everyone is welcome - see you at Oracle OpenWorld in San Francisco!

Chris Muir also will have a presentation related to JDeveloper topic at Oracle OpenWorld Unconference. His session will be focused on testing and related stuff. This session is very important, because from my practice I can see, that JDeveloper features are not used so frequently during testing phase. So, just come and see how testing should be done! ;-).
