Hello,
I am publishing a message using the .NET API.
The runtime version of IBM.XMS is v2.0.50727.
However, when I try to set the message retention as shown in the JAVA samples, by using:
sendMsg.SetIntProperty("JMS_IBM_RETAIN", 1);
I get an exception, that this property is not supported by this framework.
What is the way to publish messages that are retained in MQ?
Thank you very much,
Andrey |

Ok, just to be clear:
Why are you writing a .NET application with reference to the Java samples?
What version of WMQ do you have that version of XMS on?
Are you really attempting to create a retained publication, or just a persistent message?

Hello,
My previous post was not clear enough.
The WMQ version is Websphere MQ fix pack 7.0.1.6 .
I am trying to publish a persistent message. |

Ok, "publish" means something specific in WMQ; the publish/subscribe functionality. The term you're looking for is "put".
The property you're using is the pub/sub one. What you need is to set the message persistence.

What you need is to set the message persistence - of the MessageDescriptor structure (MQMD).

In JMS / XMS this property can be set on the destination...

Will it be convenient for you to post a sample? [: Thank you very much. |

It is:
topic://....?persistent=1 anyway, What I want is to publish to the topic as a retained message. [:
I want to simulate the "Test publication" - "retained message" checkbox in the MQ Explorer.  |

I deliberately asked:

and you said:

you actually meant "publish a retained publication" 
If you don't understand the concepts well enough to ask questions clearly, you're going to waste everyone's time including your own because we're going to give you the wrong advice!
There is a major difference between a persistent message and a retained publication. There is a major difference between putting a message and publishing to a topic.

As Vitor said, you need to know the difference between a persistent message and retained publication.
Anyway here is code snippet that publishes a retained publication.
ITextMessage msg = session.CreateTextMessage("A Retained Publication");
msg.SetIntProperty(XMSC.JMS_IBM_RETAIN, 1); |
