Mule JMS消息被截断-IBM MQ

Question

I have an issue that my jms message is not fully sent to the queue and is truncated, only 100 charachters are set into the queue. Here is my configurations:

</mule>

To make sure that the problem is not from the wepshpere mq side, i used java code with ibm API to send the message, and it was fully sent

package jms;

import javax.jms.Connection;
import javax.jms.JMSException;
import javax.jms.MessageProducer;
import javax.jms.ObjectMessage;
import javax.jms.Queue;

import javax.jms.Session;
import javax.jms.TextMessage;

import com.ibm.mq.jms.MQQueueConnectionFactory;


public class TestJMS {

    void send() {
        String destinationName = "ACCT_Q_REQ";

        MessageProducer producer = null;
        Connection connection = null;
        Session session = null;

        try {

            MQQueueConnectionFactory MQQueueConnectionFactory = new MQQueueConnectionFactory();
            MQQueueConnectionFactory.setTransportType(1);
            MQQueueConnectionFactory.setHostName("222.222.100.58");
            MQQueueConnectionFactory.setPort(1414);
            MQQueueConnectionFactory.setQueueManager("ESBDEVBKRQM");

            connection = MQQueueConnectionFactory.createConnection("Administrator", "******");

            session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
            Queue source = session.createQueue(destinationName);
            producer = session.createProducer(source);
            connection.start();

            String text = ".....";
            TextMessage objectMessage = session.createTextMessage();
            objectMessage.setText(text);
            producer.send(objectMessage);

        } catch (JMSException e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        new TestJMS().send();
    }

}

What might be the issue here?

Answer 1

You should check all the MQ relevant maximum message size limiters:

1. the MQ connection's MaxMsgLength - this is part of your MQQueueConnectionFactory
2. the queue managers maximum message length, MAXMSGL
3. the queue's MQIA_MAX_MSG_LENGTH
4. and if you are receiving messages over an MQ channel, even the channel's MAXMSGL

all of the above must be set to a value higher than 1000 for things to work...
