Name	Type	Description
JbpmCfgResource	Environment Entry	The classpath resource from which to read the jBPM configuration. Optional, defaults to jbpm.cfg.xml.
ejb/TimerEntityBean	EJB Reference	Link to the local entity bean that implements the scheduler service. Required for processes that contain timers.
jdbc/JbpmDataSource	Resource Manager Reference	Logical name of the data source that provides JDBC connections to the persistence service. Must match the hibernate.connection.datasource property in the Hibernate configuration file.
