[omniORB] Transaction question

[=?gb2312?B?1Kwg6ruzzA==?=]

omniorb-list:

	We have a product called SMS(Subscribe Management System). It is a 
CCB(Customer Care Billing) System used in DVB domain, and contains two 
server: billing server and customer server. Billing server is written using 
C++, Customer server is written using java. We uses corba for 
communications between Billing server and Customer server. Billing server 
uses omniORB-4.0.6, Customer Server uses weblogic server 9.0, and uses 
weblogic ORB to invork corba service provided by Billing server in 
sessionstateless bean. 

	We have succeeded in invorking corba service in slsb, and now my challenge 
is the tracsaction in two server must be consistent, so I think it should 
be use distributed tracsaction and two-phase commit, but omniORB-4.0.6 
doesn't provide any tracsaction support.

	Could someone give me some advice for the question below
	1¡¢Must I use distributed tracsaction and two-phase commit?
	2¡¢How can I guarantee the consistency of tracsaction? I think I can 
define corba service throws exception, and in slsb, I can catch the 
exception and the CMT mechanism could guarantee the consistency of 
tracsaction; but if exception occurs in slsb, how can I rollback the 
tracsaction in billing server?

	Any insight into the problem is appreciated.

	Thanks
	Haocheng Yuan
