Interesting post on the Oracle JDeveloper Oracle internal mailing list, answered by Andrew Robinson. Accessing a managed bean in a standard servlet scope like sessionScope or requestScope using the scope as a prefix fails if the bean instance does not exist. Thus, bean reference like #{sessionScope.myBean} may fail while #{myBean} always succeeds. The reason for [...]

A great discussion on the JDeveloper forum on OTN brough a new addition to ADF application security that I like to share.
Chapter 30 of the Oracle® Fusion Middleware Fusion Developer’s Guide for Oracle Application Development Framework 11g Release 1 explains the JAAS protection mechanism for ADF pages and Task Flows. In here it [...]

Our ADF Faces documentation contains little nuggets of poetry and wisdom that are easy to memorize helping you to better understand the product – and answer questions on OTN with it. For example, today I found and liked:
Note: If your trigger component is an inputLov or an inputComboBoxLov, and the target component is an input [...]

The call for papers for both Oracle Open World and Oracle Develop is now open here.

I have been fairly remiss in responding to comments, I have just worked my way though the backlog and now up to date. yay

So I was playing with a patch Building an testing to Jersey but I was having trouble building and running the tests. It seems that there are problems if you don't have the same specific version of Maven, (2.0.9), once that is solved you might run across another issue as the default memory given to Maven will not be enough for all the test to succeed.

The way to track the correct values is to take a look at "hudson/jersey.sh" and this will set the MAVEN_OPTS to:

In a comment on one of my posts on the AMIS technology blog I had a question on UIComponents. The question was if it is possible to modify prompts and labels of components programmatically. As a matter of fact this is possible. You can do this for the session only, or you can choose to persist these changes. In this post I first explain how to implement the "session only" functionality, and in

Here are links to some new JDeveloper and ADF Bloggers that I came across since my last bloggers list update:

Last week I finally added google tracking on a per entry to my blog, and turns out that one of the most popular entries I did is "How do I Start Learning JDeveloper and ADF" - the only problem is that was created back in the 10.1.3 days.
So here is an update with links to 11g material.

Just finished a new blog article about launching a bounded task flow in a new browser tab. This article addresses the popular tab browsing feature in browsers, showing how – assuming the business use case requires it – you do the same in ADF Faces. The specialty is that the tab browsing is not initialted [...]

Since the "normal" installer for JDeveloper 11G is not accessible using a screenreader, Oracle has provided an alternate method of installation for those people who use screenreaders. This method involves the use of a special xml file which contains the installation options.

The silent install is simple to perform once you have a silent.xml file configured to your specific situation.

In order to create a new application workspace, you need to select file –> new from the menu, and the new gallery will open.  tab twice to get to the categories list and make sure “general” is expanded.  Arrow down to “Applications” and tab to the show all descriptions checkbox and make sure it is checked. Tab again to the list of application types.

Someone on OTN asked whether they can leverage JDeveloper's JSF features but work with JBoss's Richfaces components.
I gave it a quick try out and it seems to work ok.
Here is a quick demo:

Basically the same process as using Woodstock or Trinidad or ADF Faces.

This time it is here:

Warn your friends and enemies...

I just upoaded a new how-to to ADF Code Corner. This how-to explains how to package and deploy ADF task flows – with or without dependent model projects – in ADF Libraries. In addition it explains how to import an ADF library, configure contained database connections and rename the task flow content names to be [...]

JDeveloper Accessibility Tips and Tricks

Didier's Blog 

I already posted a video that showed how to get a project from NetBeans into JDeveloper.
Dana has a blog that shows a simpler approach for NetBeans to JDeveloper migration. If you are using Maven in your NetBeans project, then you can use the Maven extension for JDeveloper to bring in the project.

Check it out here.

Just in case …

you are worried about missing bits of information about Oracle JDeveloper and ADF
you feel uncomfortable saying “If I had known this before it would have saved me …”
you don’t have time to frequently browse OTN
you enjoy technical stuff more than knowing what Paris Hilton did last week
you want to know more [...]

We had a debate in the office about how the apple iPad would affect male fashion choices. You had to store it somewhere on your person and is just too big for a normal pocket. I don't see man-bags becoming that fashionable so we had to think out of the box. Jon Russell our local artist, talented cartoonist and now fashion designer took inspiration from both Celtic and Rustic trad to produce his new iPad supporting range....

The ADFc controller provides declarative exception handling. However, if you need to customize this exception handler, for example to redirect a request to a custom session expiry page, then you can do this as follows

Create a Java class that extends AdfcExceptionHandler
Create a textfile with the name “oracle.adf.view.rich.context.Exceptionhandler” (without the quotes) and store it in .adf\META-DATA\services [...]

On one of the comments for my entry about migrating code from NetBeans to JDeveloper Peter asked if JDeveloper can work with the woodstock components.

The answer is yes - see this demo:

I have had a very busy month. I spent most of my evenings writing. Writing code? Nope, writing text! It looked like it all came at the same moment. I had 3 deadlines in January, 2 of which were in the last week.One of the things I wrote was a blog post at the AMIS blog. It was a post that I started to write some time ago, but I never took the time to finish it. It describes how to create a

The next bunch of our highly successful OTN Fusion Development Experience workshops is about to start in a couple of weeks.

These are free one day event where we spend the first half day explaining the technology through slides and demos, and then we let you actually work with the technology on your own machine - bring your laptop and we'll take care of the rest.

So Oracle now own NetBeans as well as JDeveloper - but can code be migrated between the two?

The answer is yes - and it is quite simple actually - have a look.

So I have been working on my BuildAnApp project, that I have mentioned previously, and decided to try and take the day out to build a simple RESTful interface to my ADF application module. Just a simple resource so I can create and update items from a single table.

The problem is always how to convert you objects into XML, so I decided to expose the Application Module with a Service interface. This results in an set of methods that can update the model in terms of SDO object which are easy to convert into XML.

Now that the Sun deal is done, we can finally explain our strategy for the Java development tools and what we are planning to do with the various tools.

No, we are not canceling the Oracle Java Newsletter (now called Dev2Dev), it's just that I'm quitting my moonlighting job as a newsletter editor and putting it in the capable hands of Justin from OTN.
