我正在尝试与Java建立与MQ的连接。我使用的是IBM的以下示例代码，但它可能已过时。我该如何解决问题/我错过了什么？
import com.ibm.mq.*; // Include the WebSphere MQ classes for Java package
import com.ibm.mq.jmqi.*;
import com.ibm.mq.constants.MQConstants;
public class MQSample
{
private String qManager = "your_Q_manager"; // define name of queue
// manager to connect to.
private MQQueueManager qMgr; // define a queue manager
// object
public static void main(String args[]) {
new MQSample();
}
public MQSample() {
try {
// Create a connection to the queue manager
qMgr = new MQQueueManager(qManager);
// Set up the options on the queue we wish to open...
// Note. All WebSphere MQ Options are prefixed with MQC in Java.
int openOptions = MQConstants.MQOO_INPUT_AS_Q_DEF |
MQConstants.MQOO_OUTPUT ;
// Now specify the queue that we wish to open,
// and the open options...
MQQueue system_default_local_queue =
qMgr.accessQueue("SYSTEM.DEFAULT.LOCAL.QUEUE",
openOptions);
// Define a simple WebSphere MQ message, and write some text in UTF format..
MQMessage hello_world = new MQMessage();
hello_world.writeUTF("Hello World!");
// specify the message options...
MQPutMessageOptions pmo = new MQPutMessageOptions(); // accept the // defaults,
// same as MQPMO_DEFAULT
// put the message on the queue
system_default_local_queue.put(hello_world,pmo);
// get the message back again...
// First define a WebSphere MQ message buffer to receive the message into..
MQMessage retrievedMessage = new MQMessage();
retrievedMessage.messageId = hello_world.messageId;
// Set the get message options...
MQGetMessageOptions gmo = new MQGetMessageOptions(); // accept the defaults
// same as MQGMO_DEFAULT
// get the message off the queue...
system_default_local_queue.get(retrievedMessage, gmo);
// And prove we have the message by displaying the UTF message text
String msgText = retrievedMessage.readUTF();
System.out.println("The message is: " + msgText);
// Close the queue...
system_default_local_queue.close();
// Disconnect from the queue manager
qMgr.disconnect();
}
// If an error has occurred in the above, try to identify what went wrong
// Was it a WebSphere MQ error?
catch (MQException ex)
{
System.out.println("A WebSphere MQ error occurred : Completion code " +
ex.completionCode + " Reason code " + ex.reasonCode);
}
// Was it a Java buffer space error?
catch (java.io.IOException ex)
{
System.out.println("An error occurred whilst writing to the message buffer: " + ex);
}
}
} // end of sample
我得到的错误：

将connector-1.0.jar依赖项添加到项目中。
答案 1 :(得分：0)
根据IBM，NoClassDefFoundError异常可能是由于缺少jar：“连接器无法从IBM WebSphere MQ Java客户端库中找到文件jms.jar。确保start_connector.bat中的变量MQSERIES_JAVA_LIB指向IBM WebSphere MQ Java客户端库文件夹。“
