So Whether you open a Environment or put all of function into a Command.   open environment: EnvironmentImpl environment = ((EnvironmentFactory) processEngine).openEnvironment(); try {   // create variable } finally {     environment.close(); }   using Command: processEngine.execute(new Command() {     public Object execute(Environment env) {         // create variable     } });   Furthermore, if you let spring to manage the transaction for jBPM4, you needn't do like above. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/535773#535773] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
