Class MVELSingleSessionManager

java.lang.Object
  org.jbpm.integration.console.session.AbstractSessionManager
      org.jbpm.integration.console.session.MVELSingleSessionManager

All Implemented Interfaces:

SessionManager

public class MVELSingleSessionManager
extends AbstractSessionManager

Default (MVEL) based implementation of SessionManager that relies on MVEL file aka SessionTemplate. Session template can be given in two ways:

• from classpath - default.session.template that is shipped with jbpm console
• from file system - session.template that is custom defined and location (directory) is given as system property jbpm.conf.dir that if not given defaults to value fo another system property jboss.server.config.dir
