Hello, I've searched the forums and I don't see anything quite like this one, so hopefully it's not a duplicate.
| Code: |
destination = (MQTopic) session.createTopic("topic://CARS/HONDA/#/BLUE");
System.out.println("TPwc=" + destination.getWildcardFormat());
MQTopicSubscriber subscriber = (MQTopicSubscriber) session.createSubscriber(destination);
|
I can see my wildcardFormat() is 0, which is topic level. However, when I view my subscription in MQ Explorer it shows a Wildcard usage of "Character level wildcard". I'm not sure why.
When I publish to topic "CARS/HONDA/PRELUDE/BLUE" I don't receive the publication. If I change my topic to "CARS/HONDA/PRELUDE/BLUE" it works fine.
These are all "dynamic" subscriptions/topics, so I don't have anything defined in MQSC, these topics just come and go. This is client version 7.5.
Where am I losing my wildcard format?
Thanks |

| It was the sharing conversations setting on my channel. It was set to 0, setting it to 1 allowed my subscriptions to do topic level wildcarding. |

This is certainly a very obscure change in setting. Thanks for reporting back

In general, you should not use SHARECNV(0).
This is not the first weird problem I've seen with using it.
I've gotten some 2012's because of it..
