Then I start the job executor like so:
| @Name("jbpmScheduler")
| @Scope(ScopeType.APPLICATION)
| @Startup(depends={"org.jboss.seam.bpm.jbpm"})
| @Install(dependencies="org.jboss.seam.bpm.jbpm")
| public class JbpmScheduler {
|
| @Logger
| private Log log ;
|
| @Create
| public void startup() {
| log.info("Starting the jBPM scheduler");
| start() ;
| if (isRunning()) {
| log.info("jBPM scheduler has started.");
| } else {
| log.error("jBPM scheduler was not started.") ;
| }
| }
|
| public JobExecutor getJobExecutor() {
|
| Jbpm jbpm = (Jbpm) Component.getInstance("org.jboss.seam.bpm.jbpm") ;
| if (jbpm != null) {
| return jbpm.getJbpmConfiguration().getJobExecutor() ;
| } else {
| return null ;
| }
| }
|
| private void start() {
| JobExecutor jobExecutor = getJobExecutor() ;
| if (jobExecutor != null) {
| jobExecutor.start() ;
| }
| }
|
| private void stop() {
| JobExecutor jobExecutor = getJobExecutor() ;
| if (jobExecutor != null) {
| try {
| jobExecutor.stopAndJoin() ;
| } catch (InterruptedException e) {
| log.warn( "Could not wait for job executor.", e ) ;
| }
| }
| }
|
|
| private boolean isRunning() {
| return getJobExecutor() != null && getJobExecutor().isStarted() ;
| }
|
| @Destroy
| public void shutdown() {
|
| if (isRunning()) {
| log.info("Stopping the jBPM scheduler.");
| stop() ;
| } else {
| log.debug("jBPM Scheduler can't be stopped because it was not running.");
| }
| }
|
| }
|
Any further help or comments would be greatly appreciated.
Many thanks, Pete
