I'm getting the same error also, but with ex05_1, trying client_1.

It gives me the error when trying to run the line:

dao.updateCabin(cabin_2);

there have been posts suggesting that the cause was the remote methods
throwing exceptions that are not (subclasses of or...) RemoteException,
but trying that did not work for me. This was at:
http://www.mail-archive.com/[e-mail]/msg115960.htm//www.mail-archive.com/[e-mail]/msg115960.htm

Also saw posts where suggesting adding a Home or LocalHome interface
would take care of it, at:
http://jira.jboss.com/jira/browse/EJBTHREE-1058

but adding Home and/or LocalHome interfaces did no good. I still got
the error when trying to run updateCabin().

I'll keep searching and post anything I find here.......

The book sample ex05_1 has 4 clients.

Client 1 tries to run updateCabin() within, I believe, a transaction-scoped
context.

Client 2 tries to also update the record, but it does it with a
TransactionPersistenceContextBean, which specifies:

@PersistenceContext(unitName="titan",
type=PersistenceContextType.TRANSACTION)
private EntityManager manager;

rather than:

@PersistenceContext(unitName="titan") private EntityManager manager;

that TravelAgentBean uses.

TravelAgentBean tries to use manager.merge() in its' updateCabin()
method, while TransactionPersistenceContextBean uses an
updateBedCount(int) method, which calls cabin.updateBedCount(int),
apparently bypassing the manager altogether (?).

I'm still learning this stuff, obviously; I'm not sure of the differences
between using and not using an EntityManager; it does have to do with
JTA, it seems.

I'll have to go further in the book to see where it takes me....
