Using JMS to connect to IBM MQ

Question

I want to use JMS to connect to IBM MQ. How do i specify the queuemanager, the channel and other properties ?

Answer 1

Using JNDI for connectionFactory/destinations lookups, provide the InitialContext with the following properties:

java.naming.provider.url=<ip>:<port, default is 1414>/<channel name, default channel is SYSTEM.DEF.SVRCONN>
java.naming.factory.initial=com.ibm.mq.jms.context.WMQInitialContextFactory
java.naming.security.authentication=none
java.naming.security.credentials=
java.naming.security.principal=

using WAS (Websphere Application Server) queues, the properties would be as follows:

java.naming.provider.url=iiop://<ip>:<port, the defualt is 2809>
java.naming.factory.initial=com.ibm.websphere.naming.WsnInitialContextFactory
java.naming.security.authentication=none
java.naming.security.credentials=
java.naming.security.principal=

The rest would be as follows:

Properties config = new Properties();
config.load(new FileInputStream("connectionConfig.properties"));// this file would contain the properties above
InitialContext context = new InitialContext(config);
ConnectionFactory factory = (ConnectionFactory) context.lookup("ConnectionFactory");// connection factory name
Destination destination = (Destination) context.lookup("destination");// queue/topic name

You need to create an MQQueueConnectionFactory bean and set the required properties in it.

<bean id="queueConnectionFactory" class="com.ibm.mq.jms.MQQueueConnectionFactory">
    <property name="transportType" ref="transport" />
    <property name="queueManager" value="queueManagerName" />
    <property name="hostName" value="hostName" />
    <property name="port" value="portNumber" />
    <property name="channel" value="channelName" />
</bean>
<bean id="transport"
    class="org.springframework.beans.factory.config.FieldRetrievingFactoryBean">
    <property name="staticField">
        <value>
            com.ibm.mq.jms.JMSC.MQJMS_TP_CLIENT_MQ_TCPIP
        </value>
    </property>
</bean>
