IBM MQ call failed with compcode '2' ('MQCC_FAILED') reason '2027' ('MQRC_MISSING_REPLY_TO_Q') Exception With Spring Boot

Question

I have a spring boot application which uses JMS template to communicate with queue services.

Here is my producer definition:

<bean id="jmsConnectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory">
    <property name="targetConnectionFactory">
        <bean class="org.springframework.jms.connection.UserCredentialsConnectionFactoryAdapter">
            <property name="username" value="${user}"/>
            <property name="password" value="${password}"/>
            <property name="targetConnectionFactory">
            <bean class="com.ibm.mq.jms.MQQueueConnectionFactory">
                <property name="transportType" value="1"/>
                <property name="queueManager" value="${queueManager}"/>
                <property name="hostName" value="${connName}"/>
                <property name="port" value="${connPort}" />
                <property name="channel" value="${channel}"/>
            </bean>
            </property>
        </bean>
    </property>
    <property name="sessionCacheSize" value="10"/>
    <property name="cacheConsumers" value="false"/>
</bean>

<bean id="jmsTemplate" class="org.springframework.integration.jms.DynamicJmsTemplate">
    <property name="connectionFactory" ref="jmsConnectionFactory"/>
    <property name="messageConverter">
        <bean class="org.springframework.jms.support.converter.MappingJackson2MessageConverter"></bean>
    </property>
</bean>
<!-- JMS outbound gateway -->
<int-jms:outbound-gateway
        id="myJmsOutboundGateway"
        connection-factory="jmsConnectionFactory"
        request-destination-expression="headers.request_destination_queue"
        request-channel="jmsOutboundRequestChannel"     
        reply-destination-expression="headers.reply_destination_queue"
        reply-channel="jmsOutboundReplyChannel"
        explicit-qos-enabled="true"/>

Here is consumer definition which stays in other project to listen queue:

<!-- Transation flow start -->
<bean id="inboundQueue" class="com.ibm.mq.jms.MQQueue">
    <constructor-arg index="0" value="${queueManager}"/>
    <constructor-arg index="1" value="#{'inQueue'}"/>
    <property name="targetClient" value="1" />
</bean>
 
<int:channel id="jmsOutboundChannel" />
<int-jms:outbound-channel-adapter
        id="acquirerOutboundAdapter"
        destination-name="destinationQueue"
        jms-template="jmsTemplate"
        channel="jmsOutboundChannel"/>

When I run the project and try to send message over IBM MQ, I get this exception:

JMS attempted to perform an MQPUT or MQPUT1; however IBM MQ reported an error.
Use the linked exception to determine the cause of this error.; nested exception is com.ibm.mq.MQException: JMSCMQ0001: IBM MQ call failed with compcode '2' ('MQCC_FAILED') reason '2027' ('MQRC_MISSING_REPLY_TO_Q').

When we checked headers in message in debug mode, we saw that header which told as missing stays in message headers:

jms_destination=queue:///destinationQueue
jms_timestamp=1650004155460
JMS_IBM_PutApplType=28
JMS_IBM_Format=

jms_redelivered=false
JMS_IBM_PutDate=20220415
jms_correlationId=210595709001
ReplyToQMgr=destinationQueue

Why are we facing this problem although header stays in headers? How can we solve this problem?

Answer 1

If the message type has been set to one of "Request", MQ will check for the presence of a reply to queue in the MQ header; obviously you would want the reply to queue to be present on the queue manager but I don't believe the reply to queue actually has to exist at the time the application puts the message for the put to succeed. Here is a snippet of JMS code that would demonstrate that:

Destination sendTo = session.createQueue("IN.Q");                   
Destination replyTo = session.createQueue("IN.Q.REPLY");
MessageProducer producer = session.createProducer(sendTo);
Message msg = session.createTextMessage("test"); 
msg.setIntProperty("JMS_IBM_MsgType",com.ibm.mq.constants.MQConstants.MQMT_REQUEST);
// Uncomment the line below to prevent a '2027' ('MQRC_MISSING_REPLY_TO_Q') error
// msg.setJMSReplyTo(replyTo); 
producer.send(msg);

I appreciate this isn't a complete answer but hopefully it will help you understand what is happening and focus on debugging the Spring configuration.
