Hi, I looked around and found some sample code to publish to a JBoss topic... public static boolean publish(String xml) throws Exception | { | log.info("Creating jndi context - alternatively use a jndi.properties"); | Properties properties = new Properties(); | properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); | properties.put(Context.URL_PKG_PREFIXES, "org.jnp.interfaces"); | properties.put(Context.PROVIDER_URL, "jnp://myserver:1099"); | InitialContext ctx = new InitialContext(properties); | | Topic topic = (Topic) ctx.lookup("topic/myTopic"); | TopicConnectionFactory tcf = (TopicConnectionFactory) ctx.lookup("ConnectionFactory"); | TopicConnection tc = tcf.createTopicConnection("user","pwd"); | try | { | TopicSession ts = tc.createTopicSession(false, Session.AUTO_ACKNOWLEDGE); | TopicPublisher publisher = ts.createPublisher(topic); | TextMessage message = ts.createTextMessage(xml); | | publisher.send(message); | publisher.close(); | tc.close(); | return true; | } | catch(Exception e){ | log.error("Exception thrown trying to send to topic", e); | return false; | } | finally | { | tc.close(); | } | } If I disable the subscriber to the topic and look in the JMS_MESSAGES table (HA JMS is configured), I find 8 duplicated messages. There is no looping and only a single subscriber has been configured. Since this is the first tested topic other than the samples that come already installed, this is the only custom configuration so far. I set up the topic in the *-service.xml file as follows... <mbean code="org.jboss.mq.server.jmx.Topic" | name="jboss.mq.destination:service=Topic,name=myTopic"> | <depends optional-attribute-name="DestinationManager">jboss.mq:service=DestinationManager</depends> | <depends optional-attribute-name="SecurityManager">jboss.mq:service=SecurityManager</depends> | <attribute name="SecurityConf"> | <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"/> | </security> | </attribute> | </mbean> I am not sure what could be causing the superfluous messages. Is there a known issue with publishing to topics? I am using JBoss 4.0.2 and JDK 1.5. Thanks in advance!
