Following is my environment
JBossAS [6.0.0.Final "Neo"]
HornetQ Server version 2.1.2.Final (Colmeia, 120)
I'm getting the same error described here
http://community.jboss.org/message/517604#517604
and here
http://community.jboss.org/thread/162024
Specifically, HornetQ is unable to resolve the class of an object that serves as the payload of an ObjectMessage.
The exception and stack trace are as follows:

HornetQ is able to resolve the class of an ObjectMessage when my receiving client is an MDB but not when it is a client MessageListener that I have deployed as part of a JBoss system service.
Following is a representative view of the package structure of my deployment
my.ear

|
|--------> payload-objects.jar
| |
| |--------> class(es) used as payload of ObjectMessage located here (and below.)
|
|--------> my-ejb.jar

| |--------> my-service.xml
| |
| |--------> toplevel
| | |
| | |--------> mdb
| | | |
| | | |--------> MDB's located here (and below.) HornetQ references to classes in payload-objects.jar resolve fine.
| | |
| | |--------> services
| | |
| | |--------> Other MessageListeners located here (and below.) HornetQ references to classes in payload-objects.jar fail!
|
|--------> my-war.war
|
|--------> WEB-INF
|
|--------> classes
| |
| |--------> no HornetQ MessageListeners here (or below) but other references to classes in payload-objects.jar here (and below) resolve fine.

|--------> lib

Please advise.
