Hi I am recently upgrading to Jboss 5 and started evaluating Jboss Messaging. I have configured orcale as database. Server came up properly. Later on I have added new topic configuration in destination-service.xml <mbean code="org.jboss.jms.server.destination.TopicService" | name="jboss.messaging.destination:service=Topic,name=serverPublishTopic" | xmbean-dd="xmdesc/Topic-xmbean.xml"> | <depends optional-attribute-name="ServerPeer">jboss.messaging:service=ServerPeer</depends> | <depends>jboss.messaging:service=PostOffice</depends> | <attribute name="SecurityConfig"> | <security> | <role name="guest" read="true" write="true"/> | <role name="publisher" read="true" write="true" create="false"/> | <role name="durpublisher" read="true" write="true" create="true"/> | <role name="dursubscriber" read="true" write="true" create="true"/> | </security> | </attribute> | </mbean> Once after adding the above destination I have restarted the server. It came up properly. Then I have logged into JMX_CONSOLE and find the my topic under destinations section. When I am trying to open my destination(serverPublishTopic) I am getting the following exception. I am also getting the same exception even I am trying to access any example topics. 16:16:30,761 ERROR [ExceptionUtil] Topic[(destination.getName() == NULL)] listMessagesNonDu | rableSub |
