mq的java测试类报错2539，百度无果

[康贝勒]

这个是发送的队列






这个是接收的



可以接收到消息


这是我的测试类：

package main;

import com.ibm.mq.MQEnvironment;
import com.ibm.mq.MQException;

import com.ibm.mq.MQMessage;

import com.ibm.mq.MQQueue;
import com.ibm.mq.MQQueueManager;

/*

 * 可以放入多条消息，按先进先出的方式取得
 */
public class MQTest {

	private String qManager;// QueueManager名
	private MQQueueManager qMgr;
	private MQQueue qQueue;
	String HOST_NAME;
	int PORT = 0;
	String Q_NAME;

		try {
			HOST_NAME = "10.10.10.223";// Hostname或IP
			PORT = 1414;// 要有一个侦听器，处于活动状态，且监听1414端口
			qManager = "QM_APPLE";
			Q_NAME = "Q1";// Q1是一个本地队列
			CHANNEL = "QM_ORANGE.QM_APPLE";// 连接通道
			CCSID = 1381; // 表示是简体中文，
			MQEnvironment.hostname = HOST_NAME; // 安裝MQ所在的ip address
			MQEnvironment.port = PORT; // TCP/IP port
			MQEnvironment.channel = CHANNEL;
			MQEnvironment.CCSID = CCSID;

			qMgr = new MQQueueManager(qManager);
			int qOptioin = MQC.MQOO_INPUT_AS_Q_DEF | MQC.MQOO_INQUIRE | MQC.MQOO_OUTPUT;

		} catch (MQException e) {

	}

	void finalizer() {

			qMgr.disconnect();
		} catch (MQException e) {
			System.out.println("A WebSphere MQ error occurred : Completion code " + e.completionCode
					+ " Reason Code is " + e.reasonCode);
		}
	}

	/*

	public void GetMsg() {
		try {
			MQMessage retrievedMessage = new MQMessage();

			qQueue.get(retrievedMessage, gmo);

			int length = retrievedMessage.getDataLength();

			byte[] msg = new byte[length];

			retrievedMessage.readFully(msg);
			String sMsg = new String(msg);
			System.out.println(sMsg);

		} catch (RuntimeException e) {
			e.printStackTrace();
		} catch (MQException e) {
			if (e.reasonCode != 2033) // 没有消息
			{
				e.printStackTrace();
				System.out.println("A WebSphere MQ error occurred : Completion code " + e.completionCode
						+ " Reason Code is " + e.reasonCode);
			}
		} catch (java.io.IOException e) {
			System.out.println("An error occurred whilst to the message buffer " + e);
		}
	}

	/**

	public void SendMsg(byte[] qByte) {
		try {
			MQMessage qMsg = new MQMessage();
			qMsg.write(qByte);
			MQPutMessageOptions pmo = new MQPutMessageOptions();
			qQueue.put(qMsg, pmo);

			System.out.println("The message is sent!");
			System.out.println("\tThe message is " + new String(qByte, "GBK"));

	}

	/**

		MQTest mqst = new MQTest();
		mqst.init();
		try {

			mqst.GetMsg();
		} catch (Exception e) {
			e.printStackTrace();
		}
		mqst.finalizer();
	}

}

但是报错：
MQJE001: 完成代码为 '2'，原因为 '2539'。
A WebSphere MQ error occurred : Completion code 2 Reason Code is 2539
java.lang.NullPointerException

百度找了很多没找到问题，请问这儿有没有能够解决问题的，麻烦您了，谢谢
