Build & Deployment & Run :

• This application is a webapp. Build it with Maven.
• Declaring datasource in JBoss AS : add datasource in $JBOSS_HOME/standalone/configuration/standalone.xml from jbpm6/container/standalone.xml (or using default java:jboss/datasources/ExampleDS)
• mvn clean install
• Drop war in container
• Start container
• Go to http://localhost:8080/jbpm6-web and follow the instructions

/!\ Important notes /!\

• jBPM editor is not enough to create BPMN 2.0 processes (Does not provide all BPMN2 activities). Use http://www.eclipse.org/bpmn2-modeler/
• Look in the code of Handler (e.g. ServiceTaskHandler, ReceiveTaskHandler) for modelisation or develop your own handlers
• Knowledge session execute command is synchronized
• Custom UserGroupCallback. Validates user and groups and is declared in RuntimeEnvironment.
• Use ProcessManagerBean (custom singleton EJB) and only this class to manage runtime and processes. Implement all calls to jBPM API here (for transactions).
• This example does not check if jBPM processes restart if server restarts
• Using kjars to deploy processes. Modular architecture. Kjars are automatically scanned by Drools when embedded in war.
