I'm using wso2esb4.7.0 and wso2mb-2.2.0. I wish to create jms proxy service using wso2mb. For this i have configured the wso2mb as well as wso2esb like :

Wso2esb configuration : (changes in jndi.properties)

# register some connection factories
# connectionfactory.[jndiname] = [ConnectionURL]
 connectionfactory.QueueConnectionFactory = amqp://admin:admin@clientID/carbon?brokerlist='tcp://localhost:5673'
 connectionfactory.TopicConnectionFactory = amqp://admin:admin@clientID/carbon?brokerlist='tcp://localhost:5673'


# register some queues in JNDI using the form
# queue.[jndiName] = [physicalName]
queue.MyQueue = MyQueue

changes in axis2.xml :

uncomment following code :

 <transportSender name="jms" class="org.apache.axis2.transport.jms.JMSSender"/>

 <transportReceiver name="jms" class="org.apache.axis2.transport.jms.JMSListener">
        <parameter name="myTopicConnectionFactory" locked="false">
           <parameter name="java.naming.factory.initial" locked="false">org.wso2.andes.jndi.PropertiesFileInitialContextFactory</parameter>
            <parameter name="java.naming.provider.url" locked="false">repository/conf/jndi.properties</parameter>
            <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">TopicConnectionFactory</parameter>
            <parameter name="transport.jms.ConnectionFactoryType" locked="false">topic</parameter>
        </parameter>

        <parameter name="myQueueConnectionFactory" locked="false">
            <parameter name="java.naming.factory.initial" locked="false">org.wso2.andes.jndi.PropertiesFileInitialContextFactory</parameter>
            <parameter name="java.naming.provider.url" locked="false">repository/conf/jndi.properties</parameter>
            <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">QueueConnectionFactory</parameter>
           <parameter name="transport.jms.ConnectionFactoryType" locked="false">queue</parameter>
        </parameter>

        <parameter name="default" locked="false">
            <parameter name="java.naming.factory.initial" locked="false">org.wso2.andes.jndi.PropertiesFileInitialContextFactory</parameter>
            <parameter name="java.naming.provider.url" locked="false">repository/conf/jndi.properties</parameter>
            <parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">ConnectionFactory</parameter>
            <parameter name="transport.jms.ConnectionFactoryType" locked="false">queue</parameter>
        </parameter>
    </transportReceiver>

also copied andes-client-*.jar and geronimo-jms_1.1_spec-*.jar from $MB_HOME/client-lib to $ESB_HOME/repository/components/lib

re-started servers.Till it's working fine.

Now wish to create a service with jms port. it is creating a service but immediately it goes to faulty service and esb logs it showing error like :

 ERROR - JMSListener Unexpected error when configuring service SampleJMS for the JMS transport. It will be disabled for this transport and marked as faulty.
java.lang.NullPointerException

    at org.apache.axis2.transport.base.AbstractTransportListenerEx.start(AbstractTransportListenerEx.java:83)

also while restarting it showing error like :

ERROR - BaseUtils JNDI lookup of name ConnectionFactory returned a org.wso2.andes.client.AMQQueue while a interface javax.jms.ConnectionFactory was expected [2015-01-20 10:22:27,709] ERROR - ListenerManager Couldn't initialize the jmstransport listener org.apache.axis2.transport.base.BaseTransportException: JNDI lookup of name ConnectionFactory returned a org.wso2.andes.client.AMQQueue while a interface javax.jms.ConnectionFactory was expected

My proxy configuration is :

  <target> 
      <inSequence> 
         <property name="Action" 
                   value="urn:placeOrder" 
                   scope="default" 
                   type="STRING"/> 
         <log level="full"/> 
         <send> 
            <endpoint> 
               <address uri="http://localhost:9000/services/SimpleStockQuoteService"/> 
            </endpoint> 
         </send> 
      </inSequence> 
      <outSequence> 
         <drop/> 
      </outSequence> 

Why so? is their any problem with jms configuration? Please guide me.

Can you include the XML of the failing proxy in your question too?Voicu

in jndi.properties, you've defined :

  • QueueConnectionFactory
  • TopicConnectionFactory

and in axis.xml, you use :

  • QueueConnectionFactory
  • TopicConnectionFactory
  • AND, in the default part, a "ConnectionFactory"

I don't use WSO2MB by I wonder if this would not be your problem
