First Day at OOW2009

Posted in General, Oracle, SOA & Oracle Fusion Middleware | No comments
My OpenWorld 2009 started out this morning with a keynote by Tom Kyte named "What Are We Still Doing Wrong?". A lighthearted
presentation with lots of funny examples of bad coding practises. After that, things heated up with an "OSB Deep Dive",
presented in her usual inspired – and inspiring – fashion by Deb Ayers, who clearly [...]
Session announcement: Oracle Service Bus (25 feb 2009)

Just wanted to draw your attention to a "Knowledge Center" session at AMIS this wednessday (25 feb 2009, starting at 16:30). It concerns the new Oracle Service Bus (previously the BEA Aqualogic Service Bus), and will be presented by former collegue Jeroen van Wilgenburg, now working at Xebia. Jeroen has worked with the OSB on his current project, so [...]
Accessing JVM arguments from Java (to determine if JVM is running in debug mode)

The other day, I was using the JDeveloper debugger to locally debug some code in an application that uses (and therefore becomes part of) an Oracle Coherence data grid. As it turned out, using step-by-step debugging in a JVM that is part of a Coherence cluster has significant impact on the rest of the grid. The [...]
Forcing refresh of an ADF Faces component with EVERY Partial Page Request
7/8/2008 - 6:21 pm
Posted in ADF & JHeadstart, AMIS, General, J(2)EE/Java, Java, KC Web/Java, Oracle, Web | 2 comments
Even when JSF was not around and ADF Faces was still called UIX, Oracle already had the cool "Partial Page Request" (PPR) feature. What this boils down to is that when a certain component in the page issues a "partial event" , an (AJAX-like) request will be sent to the server that (by default) only refreshes the [...]
Debug Logging in BPEL using Sensors – Part 1

When developing and/or debugging BPEL processes, the Oracle BPEL Console is your best friend. Every change to every variable, every activity that was executed, everything is right there for you to inspect, whether the instance is still in-flight or already completed. But although this sounds like the ultimate debugging tool, I’m sure you’ve noticed like [...]
EclipseLink and Oracle Coherence: a match made in heaven?
9/5/2008 - 9:57 am
Posted in General, J(2)EE/Java, KC Web/Java | No comments
Tonight Lucas, Wouter and myself went to a very interesting session at JavaOne, to hear how two of my favourite Java technologies, EclipseLink and Coherence, can work together to create the ultimate scalable JPA implementation. And if the technologies weren’t enough to make this a must-see session, then the speakers would have made it so: [...]
Subversion 1.5 Presentation at JavaOne
6/5/2008 - 12:56 am
Posted in General, KC Software Engineering, Software Development, Tools | No comments
That Subversion is popular among Java programmers is no big surprise. If it needed proof, the huge line of people waiting to get into the "Subversion 1.5: Great New Functionality For Developers" session at the first day of JavaOne 2008 would have provided it. In a 50 minute session, the audience was led through the [...]
AMIS Query on Oracle Coherence

Posted in J(2)EE/Java, Java, Java, JEE, OAS and WebLogic Server, Oracle | 1 comment
Of all the new and exciting stuff I have seen at Oracle OpenWorld this year, two new technologies (at least to me) stand out. The first is CEP (Complex Event Processing), which I am sure will be covered in another post on this Blog in soon. The other is Oracle Coherence, known as Tangosol Coherence before [...]
Another trip down memory lane at OOW: JDeveloper History
13/11/2007 - 8:25 pm
Posted in ADF & JHeadstart, General, KC Web/Java, Oracle | 1 comment
Oracle celebrates its 30th anniversary this year, and this was the main theme of Larry’s key note speech on sunday night. But there are other anniversaries to celebrate this year. It has been ten years since Oracle purchased JBuilder, buying itself into the market of Java development IDEs. This was reason for Oracle product managers [...]
Integrating JAD decompiler into JDeveloper
8/11/2007 - 7:43 pm
Posted in J(2)EE/Java, KC Web/Java, Tools | 2 comments
In JDeveloper, when debugging or otherwise navigating to classes that JDeveloper does not have the source code for, JDeveloper generates a "stub source", showing you only the fields and methods but not the source code. For many years, I have been using a neat "undocumented feature" of JDeveloper, which allows me to integrate the popular decompiler [...]
