Can you alter your usage of the driver so you change the parameters of
setTransactionIsolation? I would certainly have no problem adding more
constants/input values to support all the firebird possibilities.

Otherwise, what kind of configuration method were you thinking of? A
properties file? A setTpbMapping(Map map) method?

I thought there was a way to configure this on the
ManagedConnectionFactory: if I'm right, would you also like a way to
include the firebird constant as a key=value pair in
DriverManager.getConnection?

Thanks
