Re: same Error deserializing EJB-session on petstore, anyone help me.

[Alexey_Ryndin/Storactive]

I don't know why your orion try to passivate petstore modelUpdateManager.
(BTW I don't know what is petstore.)
And solutions, I believe, are the same: either use ejbPassivate and
ejbActivate to manage non-serializable resources or define them as
transient fields.
