Hey guys,
I am writing a C# app with XMS.NET directly translated from that nice IronPython/XMS.NET example on the web.
I verified that I can publish and subscribe using MQ Explorer but for some reason when I try to do this with my C# app I get the following error:
"The type initializer for 'IBM.XMS.WMQ.WmqConnectionFactory' threw an exception."
Here is my code for the subscriber portion of my app and thanks for the help:
| Code: |
namespace IronPythonToCSharp_Publisher
{
class Program
{
static void Main(string[] args)
{
string host = "localhost";
string port = "1414";
string mode = "1";
string qm = "QM1";
try
{
//create the connection factory
XMSFactoryFactory ff = XMSFactoryFactory.GetInstance(XMSC.CT_WMQ);
//use the connection factory factory to create a connection factory
IConnectionFactory cf = ff.CreateConnectionFactory();
//set the properties
cf.SetStringProperty(XMSC.WMQ_HOST_NAME, host);
cf.SetStringProperty(XMSC.WMQ_PORT, port);
cf.SetStringProperty(XMSC.WMQ_CONNECTION_MODE, mode);
cf.SetStringProperty(XMSC.WMQ_QUEUE_MANAGER, qm);
//create a connection
IConnection connection = cf.CreateConnection();
Console.WriteLine("Connection created");
//create a session
ISession session = connection.CreateSession(false, AcknowledgeMode.AutoAcknowledge);
Console.WriteLine("Session created");
//create a destination
IDestination destination = session.CreateTopic("topic://xms/test");
Console.WriteLine("Destination created");
//create a publisher
IMessageProducer publisher = session.CreateProducer(destination);
Console.WriteLine("Publisher created!");
//start the connection
connection.Start();
//create a text message
IMessage sendMsg = session.CreateTextMessage("Wow! this actually works! ;-)");
//send the message using the sender
publisher.Send(sendMsg);
Console.WriteLine(sendMsg);
Console.WriteLine("Message sent!");
//tidy up all the resources
publisher.Close();
Console.WriteLine("Publisher closed");
session.Close();
Console.WriteLine("Session closed");
connection.Close();
Console.WriteLine("Connection closed");
//we're finished
Console.WriteLine("Sample execution SUCCESSFUL");
}
catch (XMSException e)
{
Console.WriteLine(e.Message);
Console.WriteLine("Sample execution FAILED!");
}
catch (Exception e)
{
Console.WriteLine(e.Message);
Console.WriteLine("Sample execution FAILED!");
}
}
}
}

I think you might want to look into following code:
| Quote: |
| cf.SetStringProperty(XMSC.WMQ_PORT, port); |
and
| Quote: |
| ISession session = connection.CreateSession(false, AcknowledgeMode.AutoAcknowledge); |
I would expect that to be setIntProperty(XMSC.WMQ.PORT, port)
and I would expect that to be createSession(false, Session.AUTOACKNOWLEDGE) or something of the kind...
But for more security recheck your .NET XMS manual. I'm just looking at if from the JMS point of view.

It appears that others from a different forum got it to work for them no problem....so it seems it is something we have configured wrong with the server itself.
I went ahead and installed the required Refresh and Fix packs. Now I am receiving a different error on a different line of code. Thanks again for your help 
It happens on this line:
| Code: |
IDestination destination = session.CreateTopic("topic://xms/test");
|
Here is the exception information I received:
| Code: |
{IBM.XMS.XMSException: CWSMQ0006E: An exception was received during the call to the method WmqSession.SetupPubSub: CompCode: 2, Reason: 2085. During execution of the specified method an exception was thrown by another component. See the linked exception for more information.
at IBM.XMS.WMQ.WmqSession.ThrowExceptionReceived(Object[] messageParams, Exception caughtException, String probeId)
at IBM.XMS.WMQ.WmqSession.SetUpPubSub(Boolean startCleanup)
at IBM.XMS.WMQ.WmqSession.CreateTopic(String topicName)

2085 is a queue not found error (which the Programmer's Reference would have told you).
I would theorise that the subscription queue is either absent, misspelt or in a different case to the one specified in your code.
I'd tend to the last as the most likely...

My code only references the Queue manager not an actual queue. But it works for others. The queue name is Q1 and queue manager is QM1.
Is this topic string wrong? topic://xms/test
Should this reference the queue?
Thanks again for your help!
Take care! |

If you're getting a 2085 your application is referencing a queue (or trying to!) 
You'd need to define a subcription point by some means, which would refer to a queue, even if you're not directly referencing the queue.

I would guess that the queue manager name being supplied on the connection is different than the one being supplied on the topic definition.
And I would think that, actually, both of these should be blank.

Just to be clear, I have set this up a local machine and am trying to publish and subscribe on the same machine.
I have created a Queue manager named QM1 and a queue named Q1.
I have checked the spelling as well.
No channels have been created.
Default listener is there and hasn't been modified.
Error is: Reason 2085.
Am I missing something I should have configured?
Thanks again, Chris |

So you created a qmgr, and added a qlocal and are trying to get pub/sub to work?
Yeah, you didn't configure the broker.

Ok, when I test publishing and subscribing through MQ Explorer I don't recall setting up a broker, I just register a publisher and Subscriber and then create a test topic and it works.
How do I set up a broker?
Thanks! |

When I run the command: strmqbrk -m QM1 it says that the broker has been started.
I never "created" a broker in MQ Explorer, but this command is working says the broker is running.
Any Ideas?
Do I need to create a channel even if on a local installation? |

That is the supplied Pub/Sub broker. It's part of the standard MQ V6 install. There's nothing to "create".
Cheers.

Usually in JMS when I get a 2085 it tells me as well which queue it was trying to access so that I can fix the problem.
When I started poking with JMS and the broker
(WMB) it told me a host of queues (SYSTEM.JMS.....) were missing. I managed to get it to work by creating a few aliases and a minimum number of queues...
As well in the Topic definition you want to pass the queue name for the target (if relevant)...
Enjoy
