This story is long overdue and no its NOT about the Oracle Database 11g Database File System (DBFS). Its about an “undocumented” NFS functionality that, maybe someday, will be serviced by the XMLDB XDB Protocol Adapter.

Subversion is a great source control system. One of the great features is it’s branching and merging support. Although many developers avoid it, branching is very powerful and useful and should not be something to be afraid off but something to be familiar with.

This article contains the resources for an article on Complex Event Processing (using Oracle CEP) that is published in the March 2010 issue of the Dutch Java Magazine. This article describes the interaction between CEP and Java Applications, using examples of temperature sensors that are monitored (aggregating their readings and looking out for any broken [...]

A lot of current projects are implementing some sort of service based architecture. Testing in this architecture becomes more complex. When implementing an OSB project with Scrum you test-automation is imperative. Scrum will require more frequent testing of your system. This is only feasible (in time and money) when you automate as much as possible.   Using [...]

Mostly when you see a carousel-ish component on the internet, it is automatically showing the next entry after a few seconds. I wondered if this could be done with the ADF carousel component as well. And guess what In one of my posts on this weblog I already explained how to implement an ADF carousel component. [...]

Complicated tree structures are being used a lot within my current project. Tree nodes have elements behind them. An element is unique, but there can be multiple tree nodes for a single element.

With my current, ADF Faces 11g, project, we have a requirement that the default text in the error message box is customized. Instead of ‘Messages for this page are listed below.’ it should read some other text. When you talk about customization you say ’skinning’. Skinning allows you to customize the userinterface, i.e. change the [...]

Although it is all about ADF 11g these days there are still some challenges in ADF 10g projects that run at some of my customers. Today I finished a task in which I had to create an updatable table in which the number of shown columns wasn’t known at design time. There is the possibility [...]

In an earlier post, I showed for the Oracle SOA Suite 11g how we can use the Mediator's Java Callout functionality to integrate RESTful services into our SOA Composite applications, even though we currently have no Http Binding Service nor WSIF support (SOAP Java Binding) at our disposal in the SOA Suite – link to [...]

I wanted to take a quick look at REST(ful) WebServices and see how those can be integrated into the SCA based SOA Composite Applications that we create with the Oracle SOA Suite. Currently, it does not have the HTTP binding that the 10.1.3 release of the SOA Suite used to have. So what are the [...]

The Mediator component in SOA Suite 11g has a the option to specify a Java Callout, one for every WSDL operation. The Java Callout refers to a Java Class, either on the SOA Suite's classpath or deployed as part of the SOA Composite application. This class should implement interface oracle.tip.mediator.common.api.IJavaCallout and a convenient way of [...]
