The web-based workbench by default will install two sample repositories that contain various sample projects that help you getting started. This section shows different examples that can be found in the jbpm-playground repository (also available here: https://github.com/droolsjbpm/jbpm-playground). All these examples are high level and business oriented.
If you want to contribute with these examples please get in touch with any member of the jBPM/Drools Team.
