Re: [jira] Message Lost Problem!

[goldi <go...@freenet.de>]

Hm,

I'm a little bit confused. An enhancement? So if ServiceMix crashes and I
restart it, it could happen that there are some messages lost? (in the case
I don't use JCA)

Re: [jira] Message Lost Problem!

[Guillaume Nodet <gn...@gmail.com>]

If you don't use transactions somehow, there will always
be some points of failures in the system.  There is no
way to work around that.
The JMS flow could use transactions / acknoweldgements, but:
  * this is not the case actually
  * such a mechanism would not sure the reliability if you work with a
database, jms BC, etc ...
     the only way here is to use XA transactions.
These features are provided by the JCA flow.

If you are interested in improving the jms flow, you're more than welcome.
