Hi,
I have tried to use savepoint in jboss I got exception ,
"Since it is managed transaction rollback not allowed"
It will be great help how to avoid this error.
2) I have session bean where my transaction started it has assume 20 insert in one table at 10th insert I get duplicate
keyexception what we do in our application increase key by catching exception and proceed ahead by in postgress when
thisexception occurs my all insert gets error out. So I thought to use savepoint or any other way to avoid this
exceptionand proceed in my transaction.
Thanks,
Amar

Yes, You can, but I don't know result of this. ;) One day I worked on
couple of patches, maybe I have those somewhere to acquire this what I
assume You want.

I assume, You want your transaction to proceed when error will occur.
Yes you can make some change to ignore this, but this will not give you
expected behaviour, because error is generated on server side, and
server will rollback transaction.
But please specify more details mainly what You want achieve and what
are preconditions.
