Re: [xmlblaster] Retrieve an external custom property in the '__sys__Event' message

[Marcel Ruff <mr at marcelruff.info>]

Salut Richard,

1) Add this to xmlBlasterPlugins.xml

  <plugin create='true' id='subscriptionSpecificEvents' 
className='org.xmlBlaster.engine.EventPlugin'>
     <action do='LOAD' onStartupRunlevel='8' sequence='4'/>
     <action do='STOP' onShutdownRunlevel='7' sequence='4'/>
     <attribute 
id='eventTypes'>topic/*/event/subscribe,topic/*/event/unSubscribe</attribute>
     <attribute id='destination.publish'>
        "publish.key=<key oid='__sys__Subscribe'><__sys__internal/></key>",
        "publish.qos=<qos><expiration lifeTime='0'/><topic 
destroyDelay='30000'><persistence relating='msgUnitStore' 
type='RAM'/><queue relating='history' type='RAM'/></topic></qos>"
     </attribute>
  </plugin>

2) Start the server

 java -Dcom.sun.management.jmxremote org.xmlBlaster.Main 
-cluster.node.id heron

3) Start a listener to '__sys__Subscribe' events (just to see that it works)

java javaclients.simplereader.SimpleReaderGui

 and hit "Subscribe"

4) Do a subscribe (and unSubscribe by hitting 'u') with an added 
SubscribeQos property "myProperty"

java -Dcom.sun.management.jmxremote javaclients.HelloWorldSubscribe 
-clientProperty[myProperty] 1234

5) Enjoy

Now the SimpleReaderGui event notification contains a
<clientProperty name='myProperty'>1234</clientProperty>
markup in the UpdateQos.


IMPORTANT NOTE: Please update again from current svn as i have added an 
important recursion detection
for your case!

regards
Marcel
