Description

Some things might cause problems in an OSGi environment like

  • classloading
  • dependencies from the api to the impl (@see ACT-8)

First task is to create a valid OSGi bundle out of the Activiti jar file. I believe this would include specification of the API packages. And maybe some lifecycle methods that could delegate to ProcessEngines.init and ProcessEngines.destroy.

What interface/object would be published? A single ProcessEngine object?

I would like this to be done as a separate module called activiti-osgi. The work should be presented on a branch called https://svn.codehaus.org/activiti/activiti/branches/osgi The goal is to show in a unit test that osgi-activiti-usage bundle would be able to access the services offered from the activiti-osgi bundle.

I'll work on that. I've already raised ACT-222 to make activiti-pvm and activiti-engine valid OSGi bundles.

Anything new?
I'm looking forward to run the engine without a server, but based on OSGi. Will it run?
Is there any example available?

You can already use Activiti with Apache Karaf, so you should be fine using it in an OSGi container. Let me know if you run into problems. For an example you can look at the Activiti in Action book.

I used Eclipse Virgo's Bundlor tool to create a working MANIFEST.MF for activiti-spring bundle. Shouldn't be such a big thing to do officially either...
