Using JMS to connect to IBM MQ

问题:

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

回答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

Here's a tutorial that may help:

Also, be sure to use the docs for the right version of WMQ. V7.0 is current and v6.0 is supported until September 2011. Whichever you are using, look at the Using Java manual for the right version:

v6.0 manual
v7.0 manual

Using IBM client API

            import com.ibm.mq.MQEnvironment;             import com.ibm.mq.MQQueue;             import com.ibm.mq.MQQueueManager;             import com.ibm.mq.constants.CMQC;              public class QueueMonitoring {                  public static void main(String[] args) {                     int openOptions = CMQC.MQOO_INQUIRE | CMQC.MQOO_INPUT_AS_Q_DEF;                     MQEnvironment.hostname = "192.168.59.103";                     MQEnvironment.port = 1414;                     MQEnvironment.channel = "SYSTEM.DEF.SVRCONN";                     MQEnvironment.properties.put(CMQC.TRANSPORT_PROPERTY,CMQC.TRANSPORT_MQSERIES);                      MQQueueManager qMgr;                     try {                         qMgr = new MQQueueManager("QM1");                         MQQueue destQueue = qMgr.accessQueue("DOCKERQ", openOptions);                         System.out.println("Queue size:" + destQueue.getCurrentDepth());                         destQueue.close();                         qMgr.disconnect();                      } catch (Exception e) {                         e.printStackTrace();                     }                  }                 }

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>

the best way is to use the command line. It is a lot of fun. You could download the command reference book from http://publib.boulder.ibm.com/iseries/v5r2/ic2924/books/csqzaj05.pdf

If your MQ server is running on a windows machine, you could optionally use a MQExplorer and configure it graphically.
