Hi Sven, I think you're better of with JNI; but I'd like to suggest you use
a synched MQ intercepting the EJB/ANSI C traffic to implicitly set the
isolation lavel to serialized. The Connector API, AFAIK, won't help you
much, but could take the place of the MQ to simulate support for
trasactions.
HTH,
JP
