Hello, I am trying to compile and run the MQSample program that comes with the MQ client. It compiles fine, but throws exceptions when it runs.
This seems to indicate that I am missing mqjbnd. I have googled for similar problems but nothing has helped so far. There is a doc from IBM about this occurring on 64-bit here: "AMQ8568 RC=2495 mqjbnd was not found" (can't post the link apparently), but that does not help me as I am running on 32-bit windows for my client and server (different machines).
Other searches indicate that this problem occurs when the MQ client is not installed and the jars were copied into the environment, but I installed the client without problem.
When I run dspmqver I get this output:
| Code: |
>dspmqver -p 7
Name: WebSphere MQ
Version: 7.0.1.6
CMVC level: p701-106-110725

Build Type: Production

I searched for mqjbnd on my system and found 0 files, could the file be missing?
I've found suggestions saying that this could be a CLASSPATH issue, but I have modified it to include all of the provided jar files as someone suggested without any luck.
Any help would be much appreciated, I have been struggling to get this working for a while and can't get rid of this error. |

You WILL get this error message if you have the client installed but are trying to do a server connection instead of a client connection.
Here are a few things to check
- What type of connection are you trying to do (client / server)?
- What software have you installed (client / server)?
- Do you have your environment setup correctly (libpath)?
- Is the qmgr you are trying to connect to located on the same box?
Have fun

Thank you so much! Apparently the sample java application was trying to connect to itself, I thought it would use the environment variable that the tutorials had me set prior for the server info, but I guess java needs it explicitly set.
I resolved this issue by including com.ibm.mq.MQEnvironment and setting MQEnvironment.hostname and MQEnvironment.channel. |

Environment variable for MQServer does not work in Java.

May you show us your code? Now I am facing the same problem but I can see what I am doing wrong.
I am trying to run with a really simple code I found in the IBM website:
| Code: |
package application;
import java.util.Hashtable;
import javax.jms.Connection;
import javax.jms.DeliveryMode;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.MessageProducer;
import javax.jms.Session;
import javax.jms.TextMessage;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
public class Program {
private static final String JMSQ_JNDI_NAME = "TesteDestination";
private static final String JMSCF_JNDI_NAME = "TesteFactory";
public static void main(String [] rgstring) {
Hashtable<String, Object> hashtableEnviroment = new Hashtable<String, Object>();
String messageText = null;
try {
hashtableEnviroment.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.fscontext.RefFSContextFactory");
hashtableEnviroment.put(Context.PROVIDER_URL,"file:C:/temp/JMSAdmin");
Context context = new InitialContext(hashtableEnviroment);
// Finding the WAS QueueConnectionFactory
javax.jms.ConnectionFactory qcf = (javax.jms.ConnectionFactory) context.lookup(JMSCF_JNDI_NAME);
// Finding the Queue Destination
Destination q = (Destination) context.lookup(JMSQ_JNDI_NAME);
// Create JMS Connection
Connection connection = qcf.createConnection();
// Create JMS Session
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
// Create MessageProducer and TextMessage
MessageProducer queueSender = session.createProducer(q);
TextMessage outMessage = session.createTextMessage();
messageText = "Hello World";
outMessage.setText(messageText);
// Set type and destination and send
outMessage.setJMSType("package_received");
outMessage.setJMSDestination(q);
queueSender.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
queueSender.send(outMessage);
connection.close();
//Connection connection = factory.createConnection();
//connection.close();
System.out.println("PRESS <ENTER> TO QUIT");
//System.console().readLine();
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JMSException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
