I need to be able publish message to mq using the IBM .net client. Here is the a snippet of the code I am currently unable to get to work. Currently, this code "works", as in it runs with no errors. However, once I check if the messages have been delivered I see no logs or anything that indicates it was succesfully delivered.
| Code: |
try
{
using(IConnection connection = connectionFactory.CreateConnection())
{
using(ISession session = connetion.CreateSession(fals, AckknowledgeMode.AutoAckknowledge)
{
using(IDestination destination = CreateMqDestination(session, topicName)
{
using(IMessageProducer producer = session.CreateProducer(destination))
{
connection.Start();
IMessage msg;
msg = session.CreateTextMessage(mqMessage);
msg.JMSType = topicName;
producer.Send(msg);
}
}
}
}
public IDestination CreateMQDestination(session, topicName)
{
IDestination dest = session.CreateTopic(topicName);
dest.SetIntProperty(XMSC.DELIVERY_MODE, XMSC.DELIVERY_AS_DEST);
dest.SetIntProperty(XMSC.WMQ_TARGET_CLIENT, XMSC.WMQ_TARGET_DEST_JMS);
return dest;

Were messages delivered or not? - you didn't specify. You merely said you checked if messages were delivered.
I'll presume that messages were delivered. MQ doesn't log message delivery.

Do you have any subscribers to receive this message?
If not and you are are just testing the publisher application for the moment, you could create an admin subscriber with a queue for the messages to go to and then you would be able to know that it had worked.
Let me know if you need further help doing this.
Cheers,

Hello, we have an internal application written in .NET that has an OnMessage listener. I’m not sure if that qualifies as a subscriber but I think it does. The message, I don’t think, was delivered because none the application logs don’t indicate that anything was captured, for what it’s worth. |

Hello, sorry should have clarified. I’m pretty sure they were not delivered. We have an internal application that logs messages with the OnMessage listener. None of the application logs showed the test message I was publishing. |

It counts as a subscriber if it is using the same topic. Is it?
If you're unsure use the following MQSC command to confirm.
| Code: |
| DISPLAY TPSTATUS(your-topic) TYPE(SUB) |

Yeah the topics are the same so no issue there. Still not quite sure why the queue isn't receiving the messages that I am publishing. Is there any properties I am missing with regards to the destination? |

To discover whether the problem is with the publishing application or the subscribing application, I would recommend making a admin subscription. This will then allow you to know where to concentrate your efforts.
