I have uploaded my slides on my jBPM5 presentation on the JBoss One Day Talk last week. Enjoy!

Introducing the service repository

(If you want to help out and contribute to jBPM, read this blog all the way to the end, as we're looking for community assistance here!)

Using jBPM5, you can introduce your own domain-specific services in your processes. By defining your own services, they show up as custom service tasks in the graphical process editor. For example, if you would like to send tweets inside your business processes, a special twitter service task can be defined, as shown in the following screenshot.

Configuring domain-specific services has become even easier now, as we now allow you to import services like this from a service repository. You can just browse such a service repository and import the services you would like to use inside your processes. These will then automatically be added to your palette. You can also import a default handler that will be used to execute the service (although you're always free to override the defaults, for example for testing).

The import wizard is created as part of the latest version of the jBPM Eclipse plugin (and will be part of the next release, or you can already try it out by installing the latest plugin from the latest update site). It supports both repositories that are on your file system, or URL-based.

Click on the image below to see a screencast where we import the twitter service in a new jBPM project and create a simple process with it that sends an actual tweet.

[Note that you need the necessary twitter keys and secrets to be able to programatically send tweets to your twitter account. How to create these is explained here, but once you have these, you can just drop them in your project using a simple configuration file.]

We're building a service repository that contains predefined services that people can use out-of-the-box if they want to: http://people.redhat.com/kverlaen/repository. Currently it only contains a few services but we will migrate all existing services there over time.

And this is where we are looking for contributions! There are tons of interesting services and excellent projects that we would like to integrate with. We would like to offer out-of-the-box integration with a lot of those, by defining them as domain-specific services and adding them to the service repository, so people can import them in their processes. So if you would like to contribute integration with a service like that (e.g. facebook, google maps, etc.), or even your own project, let us know!

A lot is happening ...

There's just too much happening to blog about it all myself, but here are some interesting blog entries out there!

  • There will be a Drools & jBPM boot camp in San Francisco end of this month. It's free but you need to register. For people that are attending the RulesFest conference, definitely a must. There's one day dedicated to healthcare even. I personally won't be able to attend unfortunately, but other core developers will be. And I'll do a remote presentation on Clinical Decision Support on the healthcare day.
  • The jBPM form designer is coming along nicely! A new video, showing some of the more advanced UI components, is available here.
  • Eric Schabell put a version of the jBPM migration tooling in the cloud. This migration project helps you converting your jPDL processes into BPMN2, and they're looking for input and feedback.
  • If you live in Argentina and if you're interested in working with jBPM and Drools, there's a job opening there with one of our partners that might interest you.
