When approaching OSGi, one of the first concepts that have to be learned is the notion of a bundle. In this entry, I'd like to take a closer look of what a bundle actually is and how a vanilla jar can be transformed into an OSGi bundle.  So, without further ado,
What is a bundle?

By popular demand, the Spring Framework Maven artifacts are now being uploaded to the Spring Snapshot Maven Repository. You can find details about all of the Spring Portfolio Maven repositories in my previous post but I'll reprint the details for the Spring snapshot repository here.
The Spring Snapshot Maven Repository is located at http://s3.amazonaws.com/maven.springframework.org/snapshot. […]

Distribution
The distribution has been trimmed from 26 JARs in 2.1-m1 to 17 JARs in 2.1-m2. Take a look at the changelog for the […]

In a previous post, I described how we use a custom ANT task to upload nightly snapshots from the ANT based projects in the Spring portfolio. In this post I'll describe how we use Amazon S3 to generate pages for the snapshots from each project and allow users to download the snapshots.
As I mentioned […]

One of the interesting side effects of a solid CI structure is that when things are running reliably, new problems start to crop up. Shortly after Spring's CI system started running smoothly, our occasional space and bandwidth issues on static.springframework.org became more pronounced. Colin Sampaleanu had done research earlier on how to alleviate some of […]

Over the last couple of weeks, fellow i21 employee Costin Leau and I have been working on improving the Continuous Integration processes of the Spring projects. When we started, we had separate builds running in Cruise Control, Continuum, and even a custom cron job. We were having some trouble getting any of our […]
