I am able to successfully send and receive topic messages via Spring JMS but the messages are not being received by a normal [Topic subscriber](https://github.com/SolaceSamples/solace-samples-jms/blob/master/src/main/java/com/solace/samples/TopicSubscriber.java "Topic subscriber"). My jms code for sending and receiving is below: ``` @Autowired private JmsTemplate jmsTemplate; public void run(String... strings) throws Exception { for( int i = 0 ; i < 100; i++) { String msg = "Hello World" + i; jmsTemplate.setPubSubDomain(true); //jmsTemplate.setdu logger.info("============= Sending " + msg); this.jmsTemplate.convertAndSend("abc/topic2", msg); Thread.sleep(1000); } } } @Component static class MessageHandler { private static final Logger logger = LoggerFactory.getLogger(MessageHandler.class); @JmsListener(destination = "abc/topic2", containerFactory = "cFactory", concurrency = "2") public void processMsg(Message msg) { // Works fine, no issues. StringBuffer msgAsStr = new StringBuffer("============= Received \nHeaders:"); MessageHeaders hdrs = msg.getHeaders(); msgAsStr.append("\nUUID: "+hdrs.getId()); msgAsStr.append("\nTimestamp: "+hdrs.getTimestamp()); Iterator keyIter = hdrs.keySet().iterator(); while (keyIter.hasNext()) { String key = keyIter.next(); msgAsStr.append("\n"+key+": "+hdrs.get(key)); } msgAsStr.append("\nPayload: "+msg.getPayload()); logger.info(msgAsStr.toString()); } public CachingConnectionFactory producerCachingConnectionFactory() throws Exception { CachingConnectionFactory ccf = new CachingConnectionFactory(connectionFactory()); ccf.setSessionCacheSize(1); return ccf; } @Bean public JmsTemplate jmsTemplate() throws Exception { // CachingConnectionFactory ccf = new CachingConnectionFactory(cf); JmsTemplate jsmTemplate = new JmsTemplate(producerCachingConnectionFactory() ); jsmTemplate.setPubSubDomain(true); jsmTemplate.setDeliveryPersistent(false); // tried both true and false. //jsmTemplate.setSessionTransacted(true); // I get an exception ... isnt supported with Direct transport. return jsmTemplate; } ``` @Bean public ConnectionFactory connectionFactory() throws Exception { ``` Hashtable env = new Hashtable<>(); env.put(InitialContext.PROVIDER_URL, jndiProviderURL); env.put(Context.SECURITY_PRINCIPAL, username); env.put(Context.SECURITY_CREDENTIALS, password); System.setProperty("java.security.krb5.conf", KRB5_LOC); System.setProperty("java.security.auth.login.config", JAAS_LOC); env.put(SupportedProperty.SOLACE_JMS_AUTHENTICATION_SCHEME, SupportedProperty.AUTHENTICATION_SCHEME_GSS_KRB); env.put(SupportedProperty.SOLACE_JMS_KRB_SERVICE_NAME, "HOST"); env.put(SupportedProperty.SOLACE_JMS_VPN, vpn); env.put(SupportedProperty.SOLACE_JMS_DYNAMIC_DURABLES, false); env.put(SupportedProperty.SOLACE_JMS_DELIVER_TO_ONE_OVERRIDE , false); SolConnectionFactory cf = SolJmsUtility.createConnectionFactory(env ); return cf; } @Bean public DefaultJmsListenerContainerFactory cFactory(ConnectionFactory connectionFactory, DemoErrorHandler errorHandler) { DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory(); factory.setConnectionFactory(connectionFactory); factory.setErrorHandler(errorHandler); factory.setPubSubDomain(true); factory.setSubscriptionDurable(false); return factory; } ``` I wonder if you can spot some obvious issue here please?

Hi Ali, To clarify a few things: - The MessageHandler in the code you’re sharing is indeed receiving and processing the message? - Your other receiver, not in the post, is just the TopicSubscriber.java class as is with only a change to the `TOPIC_NAME` variable? - Can you share the rest of your class above where you autowire the jmstemplate? thanks, Marc ---

Some thing wrong with the edit functionality of this forum … posts get deleted magically. ---

Attempt No2 for a reply… pls find my answers inline. > [@marc](#): > > Hi Ali, > To clarify a few things: > > - The MessageHandler in the code you’re sharing is indeed receiving and processing the message? Yes that is correct. > - Your other receiver, not in the post, is just the TopicSubscriber.java class as is with only a change to the `TOPIC_NAME` variable? > Yap, code is below which is tried and tested as its part of a gui tool we use for testing on daily basis. ``` private void subscribeSolaceTopic(String pTopic) { try { solaceConsumer = solaceSession.getMessageConsumer(new XMLMessageListener() { public void onReceive(BytesXMLMessage msg) { LOG.info("onReceive->Message Dump: {}", msg.dump()); }); } public void onException(JCSMPException e) { LOG.error("Consumer received exception: {}", e); } }); Topic topic = JCSMPFactory.onlyInstance().createTopic(pTopic); solaceTopic = topic; solaceSession.addSubscription(topic); LOG.info("Connected. Awaiting message..."); solaceConsumer.start(); } catch (JCSMPException e1) { LOG.error(EXCEPTION_OCCURRED , e1); } } ``` > - Can you share the rest of your class above where you autowire the jmstemplate? The autowire is done on a field and its up there near the top of my first post. If you want I can try attaching the entire project ? Thanks, Ali ---

Could it be that the call below is adding some thing to the name of the topic ? this.jmsTemplate.convertAndSend(“abc/topic2”, msg) ---

Please ignore this for now … I might have found the root cause for this. Will come back if the issue still persists. Thanks, Ali ---

Thanks for the update Ali. Hope it’s working for you 😄 I’m definitely curious what the issue was if you find that it was indeed the root cause. thanks, Marc ---

Hey Marc, The receiver is basically a gui that was throwing exceptions behind the scenes because it was receiving wrong type of message. java.lang.ClassCastException: com.solacesystems.jcsmp.impl.XMLContentMessageImpl cannot be cast to com.solacesystems.jcsmp.BytesMessage To remedy this we are now using ``` jmsTemplate.convertAndSend("abc/topic2", msg.getBytes()); // instead of just msg which is a String ``` Apologies for the red herring post. Thanks, Ali ---

Ali, Excellent - glad the issue is resolved. And thanks for sharing as I’m sure this will prove to be useful to someone else as well. -Marc
