问题
I am trying to write my test message to MQ, but failed to do so.
Sharing the source-code and error:

public static void main(String[] args) {
try {
int openOptions = MQC.MQOO_INQUIRE | MQC.MQOO_INPUT_AS_Q_DEF | MQC.MQOO_OUTPUT;
MQEnvironment.hostname = "myserver_name";
MQEnvironment.port = 1417;
MQEnvironment.channel = "my_channel_name";
//MQEnvironment.properties.put(CMQC.USER_ID_PROPERTY, "admin");
//MQEnvironment.properties.put(CMQC.PASSWORD_PROPERTY, "passw0rd");
//MQEnvironment.properties.put(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES);
MQQueueManager queueManager;
queueManager = new MQQueueManager("queue_manger_name");
MQQueue destQueue = queueManager.accessQueue("queue_name", openOptions);
MQMessage hello_world = new MQMessage();
hello_world.writeUTF("Blah...blah...bleah...test message no.1...!");
MQPutMessageOptions pmo = new MQPutMessageOptions();
destQueue.put(hello_world, pmo);
destQueue.close();
queueManager.disconnect();
System.out.println("------------------------success...");
} catch (Exception e) {
System.out.println("Exception: " + e);
e.printStackTrace();
}
}
}
error message

What might be main cause of above error and solution if any??
回答1:
I don't know how many times I need to post it @ StackOverflow but do NOT use the MQEnvironment class, as it is NOT thread safe. Use a Hashtable instead. Here is a working example:
import java.io.IOException;
import java.util.Hashtable;
import com.ibm.mq.MQException;
import com.ibm.mq.MQMessage;
import com.ibm.mq.MQPutMessageOptions;
import com.ibm.mq.MQQueue;
import com.ibm.mq.MQQueueManager;
import com.ibm.mq.constants.CMQC;
