I have found the jbpm-designer project of the github project droolsjbpm. I can run this on my tomcat server but I don't use the whole web application. Is it possible to use only the bpmn2-editor without the uberfire workbench?
not really, designer as other editors in jbpm and drools are based on uberfire both client and server side. For server side it does use virtual file system as a storage (git by default). So it's embeddable but in any UF application.
Does anybody know what steps need to be done to use the local file system repository instead of the github repository?
