Know of a Java-based Workflow Engine? Is there a Java API out there for workflow, or some package that will allow me to configure workflow for my app. At my day job, we're starting to get into some significant document workflow. For our next release, we'll probably just be keying off a status field - but I'm interest if there's an easy-to-implement workflow package that we can implement now (before we hard-code too much business logic). Thanks for any suggestions! Posted in Java at Feb 04 2003, 07:14:14 PM MST 4 Comments

Werkflow looks interesting, but I couldn't find any tutorials in the 45 seconds I looked at it. Any pointers would be great.

Although I haven't had the opportunity of using it, OSWorkflow from OpenSymphony surely looks interesting.

Hi Matt, we used plain JMS in combination with home-grown MDBs (EJB 1.1 workaround) to achieve an asynchronous workflow. Since all messages are ObjectMessages, the onMessage methods tend to be rather short. The rest (which MDB receives what message) is handled by selectors. This JMS feature alone is a life-saver. For a free JMS provider check out JORAM (http://objectweb.org/joram) HTH Fokko

There are several open source options:
  • Open Business Engine
  • OSWorkflow
  • werkflow
  • jBpm
  • Open For Business' workflow component Only Open Business Engine and Open For Business' workflow component currently follow any sort of standards for workflow. All of the other engines currently have their own workflow definition language. Sincerely, Anthony Eden
