The format of the generated ID is 'key:version', and the length is constrained to 64 characters. Important to note here is that this is not the same as calling the startProcessInstanceById method, which expects the String ID that was generated at deploy time by the Flowable engine (the ID can be retrieved by calling the processDefinition.getId() method). ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("myProcess") This method will always take the latest deployed version of the process definition. This id can then be used to start a new process instance of the process definition, through the startProcessInstanceByKey method on the RuntimeService. id: this attribute is required and maps to the key property of a Flowable ProcessDefinition object.Optionally, you can also add the online schema location of the BPMN 2.0 XML schema, as an alternative to the XML catalog configuration in Eclipse. The targetNamespace can be anything and is useful for categorizing process definitions. Note that the minimal definitions element only needs the xmlns and targetNamespace declaration. An empty process definition looks like the one shown below. Within this element, multiple process definitions can be given (although our advice is to have only one process definition in each file, as this simplifies maintenance later in the development process). The root element of the BPMN 2.0 schema is the definitions element. bpmn, otherwise the engine won’t pick it up for deployment. Very little of this is specific to Eclipse, however, you can use any other tool you prefer to create XML files containing BPMN 2.0.Ĭreate a new XML file ( right-click on any project and select New→Other→XML-XML File) and give it a name. This introduction is written with the assumption you are using the Eclipse IDE to create and edit files. BPMN is a widely accepted and supported standard notation for representing processes OMG BPMN Standard.
