WSO2消息代理未收到消息

Question

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

Answer 1

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

You can find further information in the following article on WSO2 ESB and MB Integration.
