Answer 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;

/**
