    Setting Queue Max size gives errors

    Neeraj khadakkar Newbie

      Jboss AS 4.2.1/ JBM 1.3GA

      I am attempting to set the 'MaxSize' of a Queue... such that all messages that come after the maxSize is reached are dropped.
      Using the jmx-console to change this value from -1 to 1000 causes this error :

      .0.0.1-8088-1]: org.jboss.jms.server.destination.QueueService - Cannot change the value of associated server's ObjectName after initialization!
      10:24:12,693 ERROR [http-127.0.0.1-8088-1]: STDERR - [Fatal Error] :2:24: XML document structures must start and end within the same entity.

      If i attempt to set this value via the 'attribute' in the destinations xml file ...i get the error :

      My Queue config is as follows :
      <mbean code="org.jboss.jms.server.destination.QueueService"
       name="jboss.messaging.destination:service=Queue,name=UniversalResourceProcessingQueue"
       xmbean-dd="xmdesc/Queue-xmbean.xml">
       <depends optional-attribute-name="ServerPeer">jboss.messaging:service=ServerPeer</depends>
       <depends>jboss.messaging:service=PostOffice</depends>
       <attribute name="MaxSize">10000</attribute>
       <attribute name="SecurityConfig">
       <security>
       <role name="guest" read="true" write="true"/>
       </security>
       </attribute>
       </mbean>
