Welcome to the YAWL User Group website yaug.org! We would like to concentrate the know-how of all YAWL users and serve as a plattform for suggestions, discussions and collaboration. YAWL is an open source BPM/Workflow system being developed by the YAWL Foundation.
Please join our community, if you would like to take part in the YAWL User Group. Please use the public forum to ask questions about YAWL or the user group itself. For any private inquiries use our contact form.

The YAWL User Group Forum on this site becomes the single forum for questions and support on YAWL and replaces the YAWL Foundation Forum. The content of the latter can still be retrieved here: http://yawlfoundation.org/forum/
In this tutorial we show in three steps how to work with codelets in YAWL. We first create a codelet, install it and then invoke it from a YAWL workflow. We assume that you are familiar with editing and running workflows in YAWL.
In the attached zip file you can find a codelet RandomNumberCodelet.java. In order to compile it you need the YAWL library jars from here:
YAWL creates XES logs directly from the control centre. This makes it easy to do Process Mining with tools like ProM, Disco or Celonis. There is however a little problem: YAWL creates "complete" events twice for every work item. This can be seen in file processMiningSimple0.1.xes in the attachment.
We have created an XSL sheet that removes these double "complete" events. When you apply this like this
In this tutorial we show how the complexity of the control flow can be reduced by using worklets and exlets in YAWL specifications.
