I have to add some steps:

1)   Start the XmlBlaster server
2) Start subscriber
3) Start publisher and publish 50 messages
4) Subscriber reveives 50 messages
5)  Shut down the server
6)  Publish again 50 messages
7)  Start the server again
8)   Send another 50 messages
9)   Subscriber reconnects and receives 100 messages

A)
The 50 messages of 6) need to be queued on client side as no server is 
available.
This is possible out of the box only with the C++ client library and the 
Java client library.
Please set the session.name to use a postiv public sessionId, for 
example "joe/2"

B)
Further - as on 8) the subscribes is not yet up and running
it wont receive the messages if not the subscriber did a persistent
subscribe on 2)


Example:
--------
java -Dcom.sun.management.jmxremote org.xmlBlaster.Main

java javaclients.HelloWorldPublish -session.name aPublisher/1 
-numPublish 2000

java javaclients.HelloWorldSubscribe -session.name aSubscriber/1 
-persistentSubscribe true -multiSubscribe false 
-dispatch/callback/retries -1


With the above command line clients started in 3 DOS-Boxes (xterms) you can
play and simulate easily the above steps.
