RE: [JBoss-user] passivation exception

[Sternagel Annegret (PN-SYS/DAS)]

It seems that the Connection class is not serializable.
So either you can close the connection directly after use and do not hold it
as bean attribute 
or close the connection in ejbPassivate() and reopen it in ejbActivate().
