Introducing the TFS SDK for Java

We recently introduced the TFS SDK for Java, to allow Java developers to target applications to Team Foundation Server. One of the great features of an SDK for Java is that it allows cross-platform access to TFS.

As you might know, I'm the resident Mac guy on the TFS team, so I wanted to whip up a little demo for how you might use this on Mac OS. This little sample shows how to pop up a Growl notification every time a new work item is created that falls within a specific query. Obviously it's fairly simplistic, but hopefully it's a good starting point for thinking about what you might be able to do with the new SDK.
