MQ Queue Manager: if you can directly access MQQueueManager object in your working
Environment, following is the way to create the Object directly.

MQEnvironment.hostname = "yourhost.yourcompany.com";

MQEnvironment.port = CLIENT_PORT; // Mention int port here

MQEnvironment.channel = CLIENT_CHANNEL; // Menion Server connection channel here

/* Mention queueManagerName here */
 MQQueueManagerqueueManager = new MQQueueManager(queueManagerName);

Thats it. hostname, port , channel and queueManagerName can connect you to your queue Manager.

And yes. dont forget to import this:

import com.ibm.mq.MQEnvironment;
import com.ibm.mq.MQQueueManager;
