Java callout on the Oracle / AquaLogic Service Bus – Invoking static methods in any jar file
Posted by Jeroen van Wilgenburg mid-morning: October 11th, 2009
Sometimes a service bus is not sufficient for the job at hand. You can use EJB's and JMS queues, but that might be overkill. That's where a java callout might come to the rescue. This article will show you how to do a callout with 'complex' objects. On the bus you can pass around java objects or use them on the bus (this requires a small transformation step). I used the AquaLogic service bus version 10.2, but I think it should work any version that supports java callouts. The only difference can be the version of xmlbeans (AL 10.2 uses version 1.0.3)

Last week I installed WebLogic and the AquaLogic Service Bus on a Mac. There is no Mac-download on the download page, but by using the HP-UX version everything works fine, you just have to add some command line parameters.

Sorting and pagination with Hibernate Criteria – How it can go wrong with joins
Posted by Jeroen van Wilgenburg mid-morning: December 11th, 2008
Lately I ran into an annoying problem with Hibernate. I tried to do pagination on a query result which was doing an SQL-JOIN under the hood. The query before paging returned about 100 results. When I turned on paging (with 20 results per page) all the pages had less than 20 results!
The reason for this is that with a JOIN there can be duplicate results and those results are filtered out after pagination is done. In this blog I will explain how to solve those problems and it also a cleaner way to build your Criteria queries.

Posted by Jeroen van Wilgenburg around lunchtime: October 9th, 2008
Have you ever tried to pronounce a url generated by Wicket? It’s quite a tedious job and often end users want to have understandable url’s (even when that url has no meaning).
It’s is quite easy to get normal url’s in Wicket. In this article I’ll show you several solutions, the first two with plain Wicket and the final solution is with wicketstuff-annotations.
