How to subscribe on JMS topic through Mule? - mule

Question

I need to subscribe to a JMS topic through Mule. We're using Mule 3.5
I have setup this flow:
<jms:connector name="vos-jms-connector" specification="1.1"
validateConnections="true"
connectionFactoryJndiName="ConnectionFactory"
doc:name="JMS" password="guest" username="guest">
<jms:custom-jndi-name-resolver
class="org.mule.transport.jms.jndi.CachedJndiNameResolver">
<spring:property name="jndiInitialFactory"
value="org.jnp.interfaces.NamingContextFactory" />
<spring:property name="jndiProviderUrl" value="jnp://xx.xx.16.41:1099" />
</jms:custom-jndi-name-resolver>
</jms:connector>
<flow name="vcm-vos-vpo-topic" doc:name="vcm-vos-vpo-topic">
<jms:inbound-endpoint topic="VPOtopic"
connector-ref="vos-jms-connector" doc:name="VPOtopic" responseTimeout="4000" />
<logger message="request for topic" level="INFO" doc:name="Logger"/>
</flow>
When I run the Mule project I would expect that I can connect to the topic with the following java code (this runs in another project, on the same machine):
Properties props = new Properties();
props.setProperty(Context.PROVIDER_URL, "jnp://127.0.0.1:1099");
props.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
props.setProperty(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
InitialContext context = new InitialContext(props);
TopicConnectionFactory topicConnectionFactory = (TopicConnectionFactory) context.lookup("ConnectionFactory");
Topic vpoTopic = (Topic) context.lookup("VPOtopic");
However, I get a "Coneection Refused" exception:
Exception in thread "main" javax.naming.CommunicationException: Could not obtain connection to any of these urls: 127.0.0.1:1099 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 /127.0.0.1:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server /127.0.0.1:1099 [Root exception is java.net.ConnectException: Connection refused: connect]]]

How do I connect to the inbound-endpoint on my localhost?

Answer 1

Are you actually using the JNDI service?
Tipically, you don't need to set the full name on the topic attribute, just use the name:
Although is weird to read from a topic and write to the same topic.
