Re: [wsbpel] BPELJ

Oliver,

You should also look at what OASIS CAM has to offer for
transaction management and context mechanisms.

The jCAM processor is available also as open source.

Thanks, DW.

Mark,

I was just thinking of being able to place different type of transactions
within the business process, in a way similar to what the EJB model allows
you to do, but maybe it does not make sense?

Olivier, there is also the OASIS Business Transactions Protocol (BTP) for
doing transaction management.

the portability of BPEL. This reminds me of some Java extensions that can be
included in some XSLT (a vendor centric approach).

type of technology? I am talking here about WSIF. It seems to be a good
approach. The BPEL compiler will be the one optimizing access to the

you (if you would) propagate a transaction from a Java component to a Web
Service endpoint? I think that this raises the issue of not having a Web
Service Transactional framework in place in the current BPEL spec. Why not
advocating the use of WS-CAF which is the only standard in this space for
managing transactions and context propagation? (Initiatives from IBM and
Microsoft are not in any standardization bodies. Am I wrong?)
