I think you have to add a activit.cfg.xml file to make this work. That is normally done automatically by the installer.

Jup, Joachim is right. You should add a configuration file to your webapp's classpath, just the way the demo-setup does it.

Thank you for your replies.

Adding the activiti.cfg.xml to the classpath was what I had to do.

I'm not sure what I was thinking.
For some reason I was convinced that the activiti-webapp-rest was initialising a
ProcessEngine via the Config class in the spring-context.

So how does the activiti-webapp-rest get the ProcessEngine in the demo setup?
All I found in the build.xml was, that the activiti.cfg.xml is copied to the activiti-engine-examples.

I'm afraid that I'm still missing a huge bit of the overall concept.

greetings

There is a jar-file copied (activiti.cfg.xml) with activiti.cfg.xml in it in web-inf/lib in rest-webapp. When rest-webapp is initialized, all process-engine config files on classpath are initialized.
