i followed the official documentation dealing with the integration between WSO2 ESB and WSO2 MB.
https://docs.wso2.com/display/MB210/Integrating+WSO2+ESB
On my WSO2 ESB 8.1.0 i wrote a simple proxy like this:
<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
name="jobReplicaFeed"
transports="https,http"
statistics="disable"
trace="disable"
startOnLoad="true">
<target>
<inSequence>
<log level="full"/>
<send>
<endpoint key="ReplicaFeedEndpoint"/>
</send>
</inSequence>
<outSequence>
<log level="full"/>
</outSequence>
</target>
<description/>
</proxy>
where ReplicaFeedEndpoint is like the following linsting:
<endpoint xmlns="http://ws.apache.org/ns/synapse" name="ReplicaFeedEndpoint">
<address uri="jms:/REPLICA_FEED?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory&java.naming.factory.initial=org.wso2.andes.jndi.PropertiesFileInitialContextFactory&java.naming.provider.url=repository/conf/jndi.properties&transport.jms.DestinationType=topic">
<suspendOnFailure>
<progressionFactor>1.0</progressionFactor>
</suspendOnFailure>
<markForSuspension>
<retriesBeforeSuspension>0</retriesBeforeSuspension>
<retryDelay>0</retryDelay>
</markForSuspension>
</address>
</endpoint>
and this is my jndi.properties:
connectionfactory.QueueConnectionFactory = amqp://admin:admin@clientID/carbon?brokerlist='tcp://myHost:5672'
connectionfactory.TopicConnectionFactory = amqp://admin:admin@clientID/carbon?brokerlist='tcp://myHost:5672'
topic.MioEvento = REPLICA_FEED
using a simple REST client i'm trying to send a message to the proxy, expecting the same to be intercepted by the message broker. Nothing happens. Furthermore, trying different times i get randomly this exception:
TID: [0] [ESB] [2015-05-06 19:55:16,503] ERROR {org.apache.axis2.transport.jms.JMSOutTransportInfo} - Couldn't locate the JMS destination REPLICA_FEED of type topic/ extracted from the URL jms:/REPLICA_FEED?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory&java.naming.factory.initial=org.wso2.andes.jndi.PropertiesFileInitialContextFactory&java.naming.provider.url=repository/conf/jndi.properties&transport.jms.DestinationType=topic/ {org.apache.axis2.transport.jms.JMSOutTransportInfo}

What could be the problem? thanks
In the endpoint definition, the uri contains the JNDI entry to the queue, where as the transport is defined as a topic.
transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory
Should be
transport.jms.ConnectionFactoryJNDIName=TopicConnectionFactory
