[jboss-as7-dev] EJB passivation/activation, clustering and JPA extended persistence context handling...

[Scott Marlow]

Hi,

I'm looking into handling serialization of the extended persistence 
context (for both clustering and EJB3.1 passivation/activation).

The (JPA subsystem) spi is still developing for this but if anyone has 
feedback or wants to follow.  A sketch for the spi is at 
https://github.com/scottmarlow/jboss-as/blob/d7ec51ac14afb47ced7d203f8b3696c10221e9db/jpa/spi/src/main/java/org/jboss/as/jpa/spi/XPCSerializationController.java

One question that comes up is why.  Why not just throw 
NotSerializableException instead of serializing the extended persistence 
context.  If anyone feels strongly that we should throw 
NotSerializableException instead of serializing the extended persistence 
context, I'd like to hear why.

I've made internal changes on 
https://github.com/scottmarlow/jboss-as/tree/cluster1 to support 
clustering extended persistence contexts.  Next is to do the actual 
serialization.
