Generating process diagram from Java code

alexbt — Sun, 01 Jan 2012 23:38:28 GMT

Hi folks,My question is about generating Activiti BPMN 2.0 XML.Based on user interaction with our UI we need:1) Create in-memory representation of a BPMN process,2) Out of those Java objects generate an Activiti BPMN 2.0 xml that will/can be imported into Activiti Designer for further enhancements.

In older version there was Activiti-Kickstart, a web application for building (simple) bpmn-processes from user input.

It is included in Activiti 5.6, the code is now here: http://www.jorambarrez.be/blog/2011/08/31/activiti-kickstart-moved-to-github/

After deploying the processes, the engine will generate a diagram for you. You can extract it from the database. An example is here: http://forums.activiti.org/en/viewtopic.php?f=6&t=2644

Alternatively, you could generate a bunch of Java classes for the BPMN 2.0 schema (see the kickstart project for an example) and generate a process model in Java using those classes. Marshalling that to XML using jaxb should get you quite close to something you can import directly into Designer to edit further. That's the way I'd go. You can also mix in the BPMN Diagram Interchange model there which will allow you to transfer the basic layouting data to Designer.

Tiese and ingo_ri (sorry, I don't know your real name),
Thank you for your answers.
You pointed me to code that really fits my needs.
And, of course, thanks to Joram for his code.
