Creating reusable ADF Library with generic live resource bundle editing functionality and reusing it in any ADF application
1In previous articles, I have introduced functionality to centralize management of boilerplate text elements such as prompt, title, hint text and messages in resource bundles. This also allows for language or user group and other context sensitive values for these boilerplate text elements. The resource bundles, as was demonstrated, can be backed by database tables, refreshed at run time and even be edited from within the JSF application itself. The last installment in the series before this one introduced an approach that allows for live page editing with minimal impact on the page itself – through run time UI component tree manipulation. However, the code for handling the live editing and dealing with the resource bundles was still part of the application making use of that functionality. This article demonstrates how this generic functionality can be isolated in a separate ADF application, deployed to an ADF Library and reused in one or many different ADF applications.
Live update of Resource Bundle from within running ADF application
0In a number of prior articles I have discussed how resource bundles are used in ADF applications to centralize boilerplate text elements – and how such resource bundles can be implemented in the database. I have shown how various groups of users can be served with different sets of resource bundle entries (context sensitive) and how resource bundles can be refreshed at run time, without redeployment or even restart of the application. Building on top of these earlier steps, I will now add functionality to the demo application to edit the resource bundle entries live and in context of the application. That means: a user (with the proper authorization) can bring up a boilerplate text editor in the context of a specific UI component and edit the resource bundle entries associated with that component – for each of the supported languages and each of the supported context values.
Any changes made while editing are recorded in the database table under the resource bundle and can be applied to the running application through the refresh resource bundle functionality introduced earlier on.
Refresh resource bundle from within the ADF application – to absorb changes in database backed bundles
2Any web application contains boilerplate text: text that is not part of the enterprise data from web services or databases that is manipulated by the end users using the application but that is part of the application definition itself. Text that is shown as prompt, title, message, hint text and in other ways. Developers can sprinkle the boilerplate text all throughout the application, in pages, JavaScript and other code sections. But they should not do that. Changing boiler plate text is a frequent requirement from the business. Having all boilerplate text in a central location makes such changes a lot easier. Additionally, many organizations require applications to be multi-lingual: different groups of users speak different languages and want to have the application support them in their own language. That means boiler plate text is not just defined once in that central location, but once for every language the application needs to support.

Adding customization (or context sensitivity) to boilerplate text from database backed resource bundles in ADF applications

ADF 11g: Programmatically repositioning columns in a Rich Table
1Rich Tables are powerful beasts in ADF Faces. They can present tons of information in many different ways. They allow users an extensive range of manipulation – from reordering and hiding columns, changing column width to sorting and filtering the data presented in the table and detaching the table from its embedding page as well as exporting the data from the table to an Excel file. Pretty impressive. And many of the visual configurations can be stored using Change Persistence across requests and even across sessions.
One specific requirement on a recent ADF 11g project led me to investigating if and how the ordering of columns in a rich table can be manipulated programmatically (rather than having the user to it). Earlier articles on this blog discussed similar challenges: intercepting changes in the column order applied by a user (http://technology.amis.nl/2012/02/intercepting-user-customization-such-as-column-reordering-in-tables-in-adf-11g-change-persistence/) and programmatically setting the sort order for columns in a Rich Table (http://technology.amis.nl/2012/03/adf-11g-programmatically-configuring-sort-for-rich-table/). As in these cases, the solution turns out to be More >
Book Review: Oracle WebCenter 11g PS3 Administration Cookbook by Yannick Ongena
0A few months back, in August, I received an electronic copy of the book: “Oracle WebCenter 11g PS3 Administration Cookbook” by Yannick Ongena (Packt Publishing, 2011). I promised you then you write a review on it and now I finally deliver on that promise.
Main conclusion: if you want to get started with WebCenter 11g, this book will help you take your first steps on many of the most important areas of Web Center (Portal). The recipes in the book provide clear instructions on getting things going. Where the Web Center documentation can be a little overwhelming – the Web Center Developer’s Guide has 69 chapters and presumably over 1500 pages of content – Yannick’s book is clear, straightforward and easy to follow.
I am not exactly sure about the intended reader for the book. The title and Yannick’s introduction mention Administration and a technical person responsible for administration. Many recipes however discusses topics and tasks I would associate with developers. So presumably both administrators and developers will benefit from the book. Note that the traditional roles of developer, administrator and end user are not as clearly defined with Web Center Portal: business or end More >
