Webservices support in JBoss AS in Fedora

Until now the webservices support was not available in the Fedora packaged JBoss AS. The main issue was the lack of CXF stack in Fedora. It took some time to make it available in an RPMified version since CXF is a pretty big project, with many submodules and a pretty nice dependency tree.

Currently in Fedora we have JBoss AS available in version 7.1.1.Final which requires CXF 2.4.6. This is a pretty old release. I decided to upgrade the CXF stack to the latest available release from the 2.6.x series. This triggered updating the jbossws-* stack to newer versions than shipped with JBoss AS 7.1.1.Final. I did some tests and it seems that the components integrate with JBoss AS seamlessly. Either case please test your application with the new stack and report any bugs.

Generate a database schema with OpenJPA and Hibernate on JBoss AS 7

When you develop an application, sometimes you want to run it quickly and test it manually. Sometimes you want to execute some integration tests that require database access. In all of these cases you need a working database. Thanks to JPA providers we can generate the database schema based on the entity definitions. Let's quickly look at two of them: Hibernate and OpenJPA.

I'm sure you have used Hibernate before. Did you know that it has a nice feature that generates the schema in the database at application startup? You can additionally place any SQL statements you want to execute after the creation of the schema into file called import.sql.

OpenJPA and Hibernate 3 on JBoss AS in Fedora

With the upcoming new release of the JBoss AS package in Fedora you'll be able to use both the Hibernate 3 and OpenJPA JPA providers. The reason why I'm enabling this for you is that we still don't have Hibernate 4 packaged, which is a pity since Hibernate 4 is the default JPA provider in JBoss AS 7. If you want to help us with it, please consider reviewing the Gradle package.

I crafted a small application that shows how to use the two new providers. The full source code is available from my GitHub account. This application uses JSF and CDI in addition to JPA. And yes, I use both JPA providers at the same time.

HP Smart Array E200i performance

I have at home a pretty nice server: HP ML350 G5. My model has one Quad-Core Intel Xeon Processor X5355 (2.66 GHz), 8 GB of RAM and 4x 250 GB SATA II, 2.5'', 5.4k disk drives.

I have this HW for over three years now, but never really tried to do anything besides installing an operating system and grinding some boxes. Recently I decided to run some quick tests to see the actual performance of the disks.
