I'm sure this is simple... What I want to do is have a topic with a
single message. When I post a new message, I want the single message
replace with the new message for the same topic. I've tried setting
the queue and cache size to 1 but then I get overflows on the queue.
Any thoughts? David
Please set the history depth to one, see
http://www.xmlblaster.org/xmlBlaster/doc/requirements/interface.publish.html#administrative
You can try
java javaclients.HelloWorldPublish -numPublish 100
-queue/history/maxEntries 1
and use the jconsole -> MBeans -> org.xmlBlaster -> node -> ... -> topic
-> Hello
to verify.
