--------------------------------------------------------------
I am running JBOSS 5.1.0 GA, which has Quartz embedded. I have an EAR file which is \
deployed and contains OSGi bundles within it. One of the bundles is a Quartz Open \
Symphony bundle which is used be web services for scheduling. All objects deploy \
successfully, but an error is thrown when the scheduler is instantiated...

 public String start(SCHEDULE_DATA sd)   
 {
   SD2XML sd2xml = new SD2XML();
   String jobDescription = null;
   if ( sd.JOB_NAME == null || sd.JOB_NAME.length() == 0) {
     sd.JOB_NAME = UUID.randomUUID().toString();
   }
   initialize(sd);
               logger.info("Starting scheduled job: "+sd.JOB_NAME + ", jobClass: \
"+sd.JOB_CLASS+", cron expression: "+sd.CRON_EXPRESSION);  if (validateInputs() && \
bindJobClass()) {  try {
       sched = new StdSchedulerFactory().getScheduler();
     } catch (SchedulerException e) {
       logger.error(e.getLocalizedMessage());
       sd.STATUS = "FAILED";
       return sd2xml.sd2XML(sd) ;

The error occurs on the sched = new StdSchedulerFactory().getScheduler() line.......

If I remove the embedded Quartz from JBOSS the code works fine. I need to coerce \
JBOSS into resolving the conflict during runtime, so the OSGi code will work within \
the JBOSS container.

I have tried classloader isolation, EAR isolation, have played with load order or \
precedence during bootstrap to resolve classes to avoid the error...no success thus \
far.

Ideas?

Anyone else had this issue?

Thanks!
