New times bring new opportunities. Although I had a great time setting up my own company ‘PALMA IT’ I decided it was time for the next step. Redstream is a fresh new company specialized in integration technologies in the most broad sense of the word. The company is started by enthusiastic general specialists with many years [...]

Oracle ADF Basic: Partial Page Rendering with input and outputText

Pascal Alma — Sat, 10 May 2008 10:18:42 +0000

In one of our screens in our application (ADF BC + JSF) we had to make it possible to quickly enter data (to insert new records) without having to select a dropdown or List of Values, but with validation against the database. To implement this, we make use of PPR (Partial Page Rendering, a great [...]

Oracle ADF Basic: Making use of the ApplicationModule Session

Pascal Alma — Sat, 03 May 2008 18:43:10 +0000

If you have to use a where-clause being based on session-scoped parameters in several viewobjects, it might be good to know you also have a session scope in Oracle's ADF BC Application Module. You get access to it by simply calling getSession() in your ApplicationModule. On the Session object which you then receive, you can [...]

Problem with customized skin in Oracle ADF Application

Pascal Alma — Mon, 28 Apr 2008 19:32:40 +0000

For an Oracle ADF application (ADF BC + JSF 10.1.3.3) we are using a customized skin. This is a very powerful technique to have the look and feel of a JSF application being based on the companies wishes. With a few changes in an existing skin (that is for instance supplied by Oracle) you can [...]

Oracle ADF Medior: Rendering images based on BLOB columns

Pascal Alma — Tue, 22 Apr 2008 16:47:33 +0000

For my current project we are building an application with Oracle ADF 10.1.3.3 (ADF BC + JSF). One of the functionalities they want is to show images that were stored in a Blob field in the database at a JSF page. After a short search it appeared that this can be rather easily done if [...]

Pascal Alma — Sat, 19 Apr 2008 14:47:33 +0000

In a former post I described how you could get access to the selected row in you af:table in your backing bean. This post takes it a step further and shows you how to deal with a multiselect table. Let us first look at how to create a multi select table. Because this can't be done [...]

Oracle ADF Basics: Getting values of the selected row in an af:table

Pascal Alma — Tue, 15 Apr 2008 18:11:21 +0000

Here is another kind of basic thing that you would like with ADF Faces but that just isn't very intuitive. Imagine you have JSF page and you just drag-and-dropped a View Object at it as a selectable Read-Only table. Now when the 'Select' button, that is added automatically, is clicked you want to do [...]

Oracle ADF Basics: Duplicating an existing row

Pascal Alma — Wed, 09 Apr 2008 14:55:31 +0000

I don't know if it is just a coincidence but at almost all the Oracle ADF projects (ADF Business Components + Struts or JSF) I have done until now there was a need for additional functionality with which the user could duplicate a row and then modify it. After reinventing this thing several times, [...]

Luckily, version control can be considered [...]
