I am trying to get the JMSAppender in jboss-log4j.xml in JBoss 4.2.3 GA. I modify the root jboss-log4j.xml and enable JMSAppender as follows: I add my category as: <appender-ref ref="JMS"/> When I start the jboss app server, I see the following error: 22:36:50,733 INFO [Log4jService$URLWatchTimerTask] Configuring from URL: resource:jboss-log4j.xml log4j error: Error while activating options for appender named [JMS]. javax.naming.CommunicationException: Could not obtain connection to any of these urls: localhost and discovery failed with error: javax.naming.CommunicationException: Receive timed out [Root exception is java.net.SocketTimeoutException: Receive timed out] [Root exception is javax.naming.CommunicationException: Failed to connect to server localhost:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server localhost:1099 [Root exception is java.net.ConnectException: Connection refused: connect]]] at org.jnp.interfaces.NamingContext.checkRef(NamingContext.java:1562) at org.jnp. Looks like the topic is not ready yet(Which I create on the appserver using a service.xml in deploy/jms directory. How do I get past this error? thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4185896#...
