OK
1- yes the tx view to Tomcat is important and a proper implementation of
java: is the way to go
2- for the container we have a big problem
It turns out that none of the Bean Managed Transaction was really taken into
account at design time. It reads like this. BMT needs to have the instance
and more precisely the context in order to make the right decision on the Tx
management.
Now the InstanceAcquisition also needs the Tx to retrieve an instance
however: right now the stack of interceptor goes
txInterceptor -> txAcquisition
when we need
txAcquisition -> txInterceptor
so, with a chicken and egg problem... we are
fucked
Sometimes modular stuff has its limits... there might be a solution in that
we need to actually reimplement a BMTTxInterceptor and not set the
TxInterceptor for SessionBeans that work with BMT, change the order of
interceptors for these puppies and make sure the spec is met... more work
than we thought (as usual). This is a design flaw but it is good that we
are testing the current design now as opposed to down the road. Sebastien
and I are going to take a stab at it in pure XP style and see if we can come
up with something by tonight.
wish us good luck, this is not looking easy :(
