Als je dit leest en je bent Oracle professional – ontwikkelaar of administrator – is de kans groot dat je jouw carriere bent gestart in de jaren ‘90, in het tijdperk van Oracle7, Oracle Forms en Client/Server applicaties – net voor de opkomst van Java, internet, mobiel en SOA. Misschien ligt je start daar nog [...]
Java Embedded activity can call a custom Java class that relies on 3rd party Java libraries. This means that a lot of existing functionality from the Java open source community is at the disposal of the BPEL developer. This article shows a simple example of developing and deploying a BPEL process that uses Java Embedded [...]
In recent articles, I have introduced CometD as framework for Server to Client and Client to Client Push: Running CometD 2 examples – locally on Tomcat using Maven and NetBeans http://technology.amis.nl/blog/14709/running-cometd-2-examples-locally-on-tomcat-using-maven-and-netbeans, CometD 2 Java Client Sample – open project in NetBeans based on Maven pom file, modify sources and run Java Based Comet Client (http://technology.amis.nl/blog/14720/cometd-2-java-client-sample-open-project-in-netbeans-based-on-maven-pom-file-modify-sources-and-run-java-based-comet-client) [...]
While preparing for the next session in our internal SOA for Java Professionals training program on BPEL, I revisited the BPEL activity Java Embedding that allows us to enrich a BPEL process with custom, Java based functionality. I tried to determine how best to explain, present and demonstrate this activity to my colleagues. This article [...]

BPEL 2.0 introduced the forEach activity – similar to for [-loop] found in many programming languages. Oracle SOA Suite 11g adopted BPEL 2.0, first in run time (PS2) and later in Design Time (JDeveloper) as well (PS3 an beyond). For BPEL processes created using BPEL 2.0, forEach is a looping mechanism – similar to repeatUntil [...]
In a previous post I’ve explained the Schematron standard, how it works and how to use it. In the Oracle SOA Suite you can ‘Validate Semantic’ on the input (request) of a routing rule in a Mediator component by selecting a Schematron file. This is the Schemtron xml file in which you define your validation [...]
In my previous post I’ve shown how to create a composite in the Oracle SOA Suite with a simple decision table in a Business Rule Engine component. For that post I had used quite a simple data model resulting in a small xml/xsd tree. For our project I wanted to repeat the exercise with the [...]
For educational purposes I’ve created a cookbook in powerpoint format on how to create a simple decision table in Oracle SOA Suite with a Business Rule engine.
To share this I’ve uploaded it to slideshare and post it here in the Amis blog as well.

This article accompanies an article on the Architecture section of Oracle Technology Network (OTN): Implementing the Enterprise Service Bus Pattern to Expose Database Backed Services. It provides a detailed description of the implementation of the ESB architecture design pattern – the same that is introduced in the article on OTN – using Oracle Service Bus. [...]
Some time ago… at a Oracle SOA 11g project, we had to call an external webservice which took 1 to 5 minutes to respond. The composite calling this webservice was called by another composite from a BPEL process. As you might guess, we got an timeout resulting in faulted instances.
Increasing the timeout time wasn’t as [...]
