Proxies in OSGi
Over the past couple of months, we've had a number of customers report issues to us regarding
ClassNotFoundException
s and proxies in dm Server. The issue actually has to do with type visibility in OSGi and is explained very well by Peter Kriens over at the OSGi Alliance Blog. Please take a look at his [...]
Getting Started with Bundlor
As Rob's post points out, over the last few months we've learned quite a bit about how people want to manage their own OSGi applications.
We found that some developers want to manage their own bundle manifests, but need a bit of help to automate the details such as specifying package versions across a range of [...]
Spring Framework Maven Artifacts
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. [...]
Maven Artifacts
Up to this point the Spring Portfolio Maven artifacts, especially the snapshots, were inconsitently created and scattered about in various locations. Over the past couple of weeks, we've been working to get the projects to be more consistent in the creation and uploading of these artifacts.
Maven Repositories
One of the most useful improvements to the [...]
Infrastructure changes in Spring 2.1-m2

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 [...]
Spring Web Flow Bean Scopes and JSF
I've recently finished up an interesting issue in Spring Web Flow. This issue (SWF-163) dealt with adding Spring 2.0 bean scoping support for Spring Web Flow's internal scopes. The implementation isn't really that interesting (the Scope interface is pretty easy to implement after all), but I wanted to mention exactly how you would [...]
Querying and Downloading from Amazon S3
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 [...]
Uploading to Amazon S3 using a custom ANT task
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 [...]
Spring Project CI Builds
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 [...]
AOP Context Binding With Named Pointcuts
There a a ton of new features in Spring AOP including the AspectJ pointcut language, the <aop:*/> namespace, and the @AspectJ syntax support. But by far one of the most powerful aspects (forgive the pun) is the AOP context binding.
For example, let's say you want to advise a method that takes a String as [...]
