Hello,
I am using Java application running on Linux, reading from IBM.MQ topic, which errors out:
| Quote: |
Failed to decode TextMessage: JMSCMQ1049: The character set '1208(UTF- Unmappable Action: REPORT, Unmappable Replacement: 63, spaceByte: 32' cannot convert some or all of the string '[B@d9f90b' |
CCSID IBM278 is used on IBM MQ side.
My application is outputting some information from the JMS message:
| Quote: |
message.getClass()) -> com.ibm.jms.JMSTextMessage
message.getStringProperty(WMQConstants.JMS_IBM_CHARACTER_SET));
->UTF-8
message.getIntProperty("JMS_IBM_Encoding"); -> 273
message.getStringProperty("JMS_IBM_Format"). -> MQSTR
|
And here is the code:
| Code: |
import javax.jms.*;
import com.ibm.msg.client.jms.JmsFactoryFactory;
import com.ibm.msg.client.jms.JmsConnectionFactory;
import com.ibm.msg.client.wmq.WMQConstants;
import com.ibm.jms.JMSMessage;
JmsFactoryFactory ff = JmsFactoryFactory.getInstance(WMQConstants.WMQ_PROVIDER);
JmsConnectionFactory cf = ff.createConnectionFactory();
cf.setStringProperty(WMQConstants.WMQ_HOST_NAME, host);
cf.setIntProperty(WMQConstants.WMQ_PORT, port);
cf.setStringProperty(WMQConstants.WMQ_CHANNEL, channel);
cf.setStringProperty(WMQConstants.WMQ_QUEUE_MANAGER, queueManager);
cf.setStringProperty(WMQConstants.WMQ_SSL_CIPHER_SUITE, "*TLS12");
cf.setIntProperty(WMQConstants.WMQ_CCSID, 1208);
cf.setIntProperty(WMQConstants.WMQ_CONNECTION_MODE, WMQConstants.WMQ_CM_CLIENT);
cf.setStringProperty(WMQConstants.WMQ_APPLICATIONNAME, "ReadMQTopicDurable");
Connection connection = cf.createConnection(user, password);
connection.setClientID(clientId);
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
connection.start();
.
.
Topic topic = session.createTopic(topicString);
MessageConsumer consumer = session.createDurableSubscriber(topic, subscriptionName);
.
.
Message message = (JMSMessage) consumer.receive(10000);
.
.
String text = ((TextMessage) message).getText();

I think the code is quite straightforward, and attempting to tell that localal CCSID is 1208.
What is the missing part, should the client somehow tell to IBM MQ manager that conversion has to be done, or there is something to be done configuration of MQ manager?
I think that seeing Message Encoding: 273 (Little-endian integer, z/OS floating point) in the message and character encoding seen as UTF-8 looks wrong, and that some kind of conversion is missing. Maybe message encoding should be Limux/x86 (546) instead of Linux/sparc(273).

Is your data really MQSTR (string)? Or something else?
