Question

I am trying to publish a simple message to ibmmq using java.The message sending is successful.But when i check the queue on ibm console .The Message is showed as

But I am expecting as simple String.

Here is my code.when I am trying to convert I am getting below message The message of type jms_bytes can not have its body assigned to java.lang.String

import com.ibm.mq.*;
import com.ibm.mq.constants.MQConstants;

            // particularly for applications using client bindings.
            pmo.options = MQConstants.MQPMO_ASYNC_RESPONSE;

            // create message
            MQMessage mqMessage = new MQMessage();


            System.out.println("Writing message to queue: " + QUEUE);
            mqMessage.writeString(message.toString());

            // Put message on queue
            queue.put(mqMessage, pmo);

            // Close queue
            queue.close();

            // Get status
            MQAsyncStatus asyncStatus = qMgr.getAsyncStatus();

            // Print status code (0 = successful)
            System.out.println(asyncStatus.reasonCode);

        } catch (MQException e) {
            System.out.println("The connection to MQ could not be established." + e.getMessage());

        } catch (IOException e) {
            System.out.println("Error while writing message." +
                    e.getMessage());
        } finally {
            try {
                qMgr.disconnect();
            } catch (MQException e) {
                System.out.println("The connection could not be closed." +
                        e.getMessage());
            }
        }
    }


    public static void main(String[] args) {

         putMsgOnQueue("WELCOME");
    }
}

ANY Help Would be Appreciated.

Answer 1

The default message format is MQFMT_NONE. This means the message body consists of bytes. Your code is not setting message format. So my thinking is that MQ Console is indicating such messages as binary.

Suggest you set the message format as string and run. This sets the message format as string.

        MQMessage mqMessage = new MQMessage();
        mqMessage.format = MQConstants.MQFMT_STRING;
