Yesterday (yes, during my three week holiday) I visited the presentation of a colleague about SOA/ESB with Mule. Since the crowd was mixed, and not everybody was custom to ESB concepts it took a while to get to the more interesting parts… but overall it was a worthwhile presentation; I really think Erik managed to [...]

During my three week holiday I’ll be constructing a room and vestibule on our second floor. A new staircase, boiler and eventually a dormer will be fitted by contractors.
Occasionally I’ll be posting pictures of the progress on my Flickr account.
Oh, and being the nerd I am… I couldn’t get any of the free CAD programs [...]

With some tweaking I managed to get one of the webapps in our current project to run using terracotta to cluster caches. The only modification I had to make was related to one of my objects not being threadsafe; actually I solved a potential concurrency problem.
Configuring Terracotta proved to be a bit more complex then [...]

During the J-Spring conference yesterday I visited the session on Terracotta; I liked what I saw and started experimenting with it right away. Probably shouldn't have started with a complex application... had a lot of problems there.
I decided to step back a bit and set up two simple webapplications which put something in the session. [...]

Today I visited the JSpring conference organized by the Dutch Java Usergroup (NLJUG). I met lot's of people I hadn't seen for a while, amongst them the lead developer of gaphor nice to meet up again after almost 3 years.
Keynote
This year over a 1000 visitors are expected to attend the JSpring 2007 conference. The usergroup [...]

About two weeks ago I migrated our project from spring 2.0.2 to the latest version available version in the maven repository at that time 2.0.4. The transition was smooth. It took a couple of days before I started realizing that the strange bugs (mostly in binding of primitives) surfacing in tested/accepted code where probably related [...]

While using Compass in the complex environment of our current project we ran into some rather nasty problems; some of the related to bugs in the Compass codebase. Currently we've got it all setup and running, and apart from some performance issues (simple queries taking 16 seconds!) it all seems fine.
But since word got out [...]

During the course last week Christian already mentioned the upcoming 'Horizontal Partitioning' extension for Hibernate. What he didn't mention was that it would be donated by Google!
Yesterday the Hibernate site displayed a new toplevel module called Shards. Shards offers critical data clustering and support for horizontal partitioning (also called sharding) to Hibernate. Cool... what does [...]

Today the training continued, full speed ahead. We covered some really handy topics like:

Queries, Criteria API, Filters
Application design with Hibernate
Performance tuning
Deployment
Caching

I found it quite usefull to have an in-depth view on the way the second level cache (and thus query cache) work. Application design was primarely focussed on using EJB3 for what we call the [...]

Today was the first day of the two-day Hibernate Advanced (H267) training which I'm attending. Most of the stuff discussed isn't new to me, but hearing explanations of certain side effects by one of the Hibernate gurus (Christian Bauer, (co)author of Java Persistence with Hibernate and Hibernate in Action) is actually a really nice [...]
