如何实现Web服务事务？

Question

Is there a Java tool for choreographing web services that makes it easy to deal with transactions?

In my use case I want to chain 2 SOAP web services: the first will perform a debit into a client's bank account and the second will recharge his cell phone for the corresponding amount. How can I implement this sequence of web services calls transactionally?

I briefly looked at Apache Camel but it doesn't seem to be the most adequate tool.

Thanks.

If your web-services are implemented using SOAP, you can implement 2-phase commit with WS-AtomicTransaction extension. These articles go into details how it can be implemented:

• Using Web Services Atomic Transactions (Java)
• Coordinating Web Services Activities with WS-Coordination, WS-AtomicTransaction, and WS-BusinessActivity (.NET, but the concept is the same)
