Multiple messages are getting logged in the Topic for a single message push

[rakesh.arora]

Hi All,

I configured a HornetQ Topic in JBoss.

This Topic has 2 subscriber associated with it.

When I push a message to this topic [with help of org.springframework.jms.core.JmsTemplate send() method], I get to see in JBoss console that, 2 messages are getting logged in this topic with the same content.

Also I have MDB [Message driver bean] associated with this Topic, which are also able to process 2 messages from this topic.

Please help with the reason for this behavior as I need only one message in the topic.

Regards,

Rakesh

I dont really understand your problem, could you explain more clearly with some example config, code etc.

[rakesh.arora]

Below are the source codes snippets, I used to configure/send the message to topic.

But when I send a single message to Topic, it shows 2 message in the topic [in jboss admin console and in message driven bean].

Let me know, if you need other details.

The below way I configured the topic in jboss:

<jms-topic name="psdFarmPostageRefundTransactionRequestTopic">

   <entry name="java:/jboss/topic/psdFarmPostageRefundTransactionRequestTopic"/>

   <entry name="java:/jboss/exported/jms/topic/psdFarmPostageRefundTransactionRequestTopic"/>

</jms-topic>

<address-setting match="jms.topic.psdFarmPostageRefundTransactionRequestTopic">

   <expiry-address>jms.queue.psdFarmPostageRefundTransactionRequestExpiryQueue</expiry-address>

   <redelivery-delay>0</redelivery-delay>

   <max-delivery-attempts>3</max-delivery-attempts>

   <redistribution-delay>0</redistribution-delay>

</address-setting>

The below way I configured the JmsTemplate

<bean id="RefundRefillJmsTemplate" class="org.springframework.jms.core.JmsTemplate">

   <property name="connectionFactory" ref="refundConFactory"/>

   <property name="defaultDestination" ref="refundRefillRequestQueue"/>

</bean>

<jee:jndi-lookup id="refundConFactory" jndi-name="java:/ConnectionFactory"

   resource-ref="false" expected-type="javax.jms.ConnectionFactory"/>

<jee:jndi-lookup id="refundRefillRequestQueue"

   jndi-name="java:/jboss/queue/psdFarmPostageRefundTransactionQueue" expected-type="javax.jms.Destination"

   resource-ref="false"/>

Java code to send the message:

@Autowired

JmsTemplate RefundRefillJmsTemplate;

this.RefundRefillJmsTemplate.send(new MessageCreator() {

   @Override

   public Message createMessage(Session session) throws JMSException {

  TextMessage message = session.createTextMessage(transactionDispenseRequestString);

  message.setJMSCorrelationID(correlationId);

   return message;

  }

});

and what issue are you exactly seeing?

[rakesh.arora]

2 messages are getting logged in the topic [with the same content] for a single message send using jmstemplate.send() method

[ataylor]

what do you mean by logged? are you saying the MDB is receiving the message twice?

[rakesh.arora]

yes, you are right. MDB is receiving the message twice. Even I am able to see 2 messages in the topic from JBoss console as well.

[ataylor]

it can only be a spring thing, I would remove the spring stuff and run pure JMS as a start point.
