MBean packaging in jar file, or deployment descriptor failed

[alanc_yang]

I encountered the deployment problem with an MBean. I don't know this was caused by the deployment descriptor or the packaging of MBean in jar file that it supposed to be packaged in sar? Does MBean need to be packaged in SAR but not JAR? Also, can session bean then be packaged in SAR together with MBean?

Thank you for your help.
