OOW 2012: My ADF OOW 2012 schedule
0This years visit to Oracle Open World is for me the best of both worlds. First of all I get to attend one of the biggest, if not the biggest, IT conferences in the world. Second, I have two presentations. Both are on Sunday afternoon. The first one is a Fusion Middleware Live Development session where we as a team show you the steps involved in creating an application using nearly all parts of Fusion Middleware. My role in the team is to explain how we build the UI part of the application and how we used ADF to do that. Also I will show you how you can create an interactive dashboard using DVT components such as graphs and gauges. More info on this session can be found here.
Right in the middle of this session I have to leave the room in order to go to my next presentation. This presentation is called “mobile development with Oracle JDeveloper and ADF”. In this session I show you some of the options that you have if you want to extend your enterprise application to mobile devices. I cannot go into much detail yet. Having said that, I’ve probably said enough. More info is available here.
After my presentation I head straight to the Oracle Benelux Networking Event which is More >
ADF: Cloning personalizations between users – read and write MDS Customization documents
0In a recent post I wrote how wonderful the ADF support for user level customizations or personalizations is, and then I went on to explain how the user can be enabled to remove her own personalizations (http://technology.amis.nl/2012/09/27/adf-undo-the-users-page-personalizations-query-and-manipulate-mds/). This article a sequel to that story. It will introduce the capability for one user to clone the personalizations from another user. This means at the background that the document that contains the customizations for a page for the ‘source user’ is read and a new document with the exact same contents is written for the ‘target user’ who will then have personalizations that are at that time exactly the same as those of the source user. There is no link between the two documents – they are both on their own. Any pre-existing personalizations for the target user are lost in this process.
Note: I do not talk about the privileges that you want to define in order to not have anyone copying from just anyone else. Also note that I discuss cloning the personalizations for a single page only. Copying all personalizations from one user to another however is a very simple extension of what More >
ADF: undo the user’s page personalizations – query and manipulate MDS
0One of the quite powerful features of ADF is the built in support user customizations also known as personalizations. A user can apply changes to an ADF web page – rearranging some of the layout, configuring advanced components such as tables and generally fine tuning the look and feel to the user’s individual needs. If the application is so configured, these changes are retained during the session (for each next visit to the page) or even across sessions (for each next visit to the page, also after an intermediate log out, in an entirely new session).
The framework provides declarative support for registering and reapplying the personalizations made by the user. These are held in the MDS Repository, in an XML file that contains the deltas that the user is (indirectly) requesting to have applied on top of the base sources of the application.
The framework does not have built in out of the box support for resetting the page – returning it to its factory level, the state in which the developers created it. The customization document needs to be removed from the MDS repository when the user wants to undo the personalizations made. To accomplish this, we need to write a little code More >
Develop and Deploy ADF applications – free of charge using the new ADF Essentials
1In a long hoped for but little anticipated move, Oracle yesterday announced ADF Essentials – the free edition of the ADF framework. Oracle now offers a complete free stack to develop and deploy applications – with Oracle Database XE, GlassFish Open Source Edition and ADF Essentials, optionally running on Oracle Enterprise Linux. It’s a red LAMP if you will.
ADF Essentials is exactly the same as ADF – it is just a subset of ADF. Even some of the highly advanced features in ADF are included in ADF Essentials – such as Data Visualization (DVT), Business Components (ADF BC), Data Binding and Taskflows. The parts not included in ADF Essentials are by and large more for specific use cases – ADF Mobile, Desktop Integration, Customization – or targeted at integration with other components in the Oracle Fusion Middleware stack – such as Data Controls for Essbase, BI and BAM.
Some of the features of ADF that are not available with Essentials that are unfortunate to let go off: ADF Security (!), publication of ADF BC as Web Service, the Web Service Data Control and remote taskflows. However, for most of these features, alternative solutions can be created or are already available – such as More >
ADF BC: How to customize the RowImpl class for an Entity Object as site level customization
0Last week I have been teaching a two day workshop on customization – one of the most powerful framework facilities in ADF. Customizations allows you to create a set of modifications (or even multiple sets of modifications) on top of a base application. The behavior and appearance of the application can be fine tuned to the specific needs of a site (or instance) of the application, or even to the desires of specific user groups on such a site. Especially for ISVs who develop their products using ADF and who would like to create and ship a single version of the application yet allow customers during implementation to do fine tuning according to local requirements, customization is fantastic feature. It allows the creation of customizations that are separate from the core code and that will survive new releases of the base application.
In future blogs, I will tell you more about customization. In this article, I will focus on a specific aspect of customization of ADF applications that may not be as straightforward. It concerns the definition of the RowImpl class for an Entity Object (or any Java Class referenced from ADF BC components).
Our specific need is that the application ships More >
The ADF must-go-to session at OOW 2012: the ADF EMG meeting on Sunday 30th September
0Just like the previous two years, ADF will be one of the major topics at Oracle Open World 2012. Wherever you turn your head, ADF based screens will be right in your face. Almost every UI coming out of Oracle is developed using ADF. And a rapidly increasing number of developers around the world – either with a classic Forms background, a Java/JEE history or fresh from school – is adopting ADF as their primary development framework and churning out new applications in enterprises and government organizations around the world. The advance guard of ADF developers, most of them member of the ADF Enterprise Methodology Group, will convene on Sunday September 30th, on the opening day of Oracle Open World 2012. From 9 AM until 4 PM, Moscone South room 305 will be center of the ADF Universe. Expect every one – from Oracle product manager and ADF engineer, ACE and ACE Director, ADF Developer and Architect – to be there, to share experiences, envision the future and teach each other tricks and insights.
If you have any interest in ADF – because you are already working with it, or are contemplating to start working with it or just want to get a feel for what it is and what it entails to use More >
