Re: [xmlblaster] message ordering

Hi, I've started using xmlBlaster and it looks very promising. I have some
questions to more experienced xmlblaster users or developers:
Is there a way to affect the way the messages are ordered before they're
sent to a subscriber ? The problem is that I need to receive messages in
the same order they're sent to xmlblaster server - now, when I subscribe
a topic with 'wantInitialUpdate' set to 'true' and HistoryQos with
maxEntries
set to 10 I tend to recieve messages with higher timestamp first.
Thanks in advance

Ok, i have added now a QoS to change the
delivery ordering of history entries, see
http://www.xmlblaster.org/xmlBlaster/doc/requirements/interface.subscribe.html
with QoS
<history numEntries='10' newestFirst='false'/>
Please check out the newest with cvs.
You can play with it:
java org.xmlBlaster.Main
java javaclients.HelloWorldPublish -numPublish 1000 -persistent false -priority 5
-> publish some messages and start a subscriber:
java javaclients.HelloWorldSubscribe -historyNumUpdates 10 -historyNewestFirst false
