[xmlblaster] reliability of publish
I want to transport mission-critical messages over xmlBlaster, and the client side persistence
is not supposed to be used. Unfortunately, I find no way (both in Java and C++) to make sure
whether the messages have been published successfully (I mean, persisted in the server side).
It seems that the client side logic always put the messages in the client queue, and once
queued, the message is out of control. If the server side is not accessible, we may get an
exception or a Constant.INFO_QUEUED stateinfo on publish(); but in either case the message
still stays in the client queue. Now, if our client crashes, the message is lost; if the
server becomes accessible, the message will be re-published automatically.
I tried following codes:
ProtocolPluginManager mgr = glob.getProtocolPluginManager();
I_XmlBlasterConnection driver = mgr.getPlugin("IOR", "1.0");
It's OK to work around the problem, but noway elegant I think :), because the client side plugin
workflow is completely short-cutted. Any better solution please?
