Sigh, since the approach of using DateTime worked, I've now changed all of the code to use DateTime rather than LocalDateTime. This shouldn't cause too many issues, since here in NZ we only have the one (practical) timezone.
I'm not sure about changing Glassfish's serialization, there might be a technique. My understanding is that around about J2EE 3 or so the standard changed to specify RMI/IIOP so that J2EE application servers could inter-operate with other Corba servers. Glassfish being a Sun thing was/is pretty good about following the standards. For example WebLogic uses it's own T3 protocol by default as a point of differentiation. Time constraints mean I've had to move on but thanks anyway for the feedback. - Richard P. -----Original Message----- From: Stephen Colebourne [mailto:scolebou...@joda.org] Sent: Tuesday, 2 November 2010 12:19 p.m. To: Discussion of the Joda project Subject: Re: [Joda-interest] LocalDateTime not able to traverse EJB calls I've had a look at the code, and it looks complex but reasonably sound at a glance. Id' be surprised if nobody has used it in EJB. I thought EJB used serialization, not CORBA. Is there a switch to change it? As you say, my tests show that regular serialization works fine. The only place it might go wrong that I could see is if readObject() isn't called on AssembledChronology. Maybe you can breakpoint that.
