[jboss-user] [JBoss Messaging] - Re: ClassCastException when casting ObjectMessage object

[chicken]

after I added these line of codes in the Catch clause: 
	System.out.println(CustomMessageBean.class.getClassLoader().toString() + " - " + CustomMessageBean.class.getProtectionDomain().getCodeSource().getLocation().toString());
  | 	System.out.println(mailBeanJMS.getClass().getClassLoader().toString() + " - " + mailBeanJMS.getClass().getProtectionDomain().getCodeSource().getLocation().toString());

mailBeanJMS is an object of CustomMessageBean type
I get new error: 
17:59:05,623 INFO  [STDOUT] ERROR.  : java.lang.ClassCastException: mail.CustomMessageBean

The eventual following stack trace is caused by an error thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access, and has no functional impact.
