[SOLVED] connecting Mule ESB to OpenMQ broker

connecting Mule ESB to OpenMQ broker

I'm trying to connect Mule ESB to an existing OpenMQ broker. Building from the mulesoft docs for openmq integration, I have the following flow;

<jms:custom-connector name="Custom_JMS" specification="1.1" 
                      class="com.sun.messaging.ConnectionFactory" 
                      validateConnections="true" doc:name="Custom JMS"/>

<flow name="EchoFlow" doc:name="EchoFlow">

    <jms:inbound-endpoint doc:name="JMS"
                          connector-ref="Custom_JMS" responseTimeout="1000" 
                          topic="mytopic"/>

    <echo-component doc:name="Echo"/>
    <logger message="#[message:payload]" doc:name="Logger"/>
</flow>

However, I get an error at runtime;

[02-26 10:54:08] ERROR DefaultMuleApplication [main]: null
org.springframework.beans.NotWritablePropertyException: Invalid property 'acknowledgementMode' of bean class [com.sun.messaging.ConnectionFactory]: Bean property 'acknowledgementMode' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

I have the feeling several elements have been left out of the example. Can someone tell me what's missing?

Solution

AFAIK custom-connector needs a class that extends org.mule.transport.jms.JmsConnector. Try this instead:

<spring:bean name="connectionFactory" class="com.sun.messaging.ConnectionFactory"/>

<jms:connector name="JMSConnector"
    connectionFactory-ref="connectionFactory"
    specification="1.1"/>
