JMSXGroupSeq question

brgorrie Nov 30, 2009 4:09 AM

Hi,

Why is line 96 in HornetQConnectionMetaData.java commented out? Its the line that adds JMSXGroupSeq to the list of supported JMSX Property names.

HornetQ actually supports the the property, at least as well as OpenMQ does.

Please let me know if you need any more information,

Cheers,

Brian.

HornetQ doesn't support JMSXGroupSeq, it only supports JMSXGroupID

Hi,

Please check the following items:
1) message-grouping.xml
2) the message group jms example
3) JMSBridgeTest.java

HornetQ supports the setting of the JMSXGroupSeq property and the delivery of its value through to the client.

I'm thinking that the underlying message ordering mechanism used by HornetQ guarrantees the order of the messages so JMSXGroupSeq is just a decoration.

That is the minimum needed to support the property.

Looking at OpenMQ (which returns the property in its list of supported properties) that is all OpenMQ does.

So I'm not sure that line needs to be commented out.

Please let me know if you need any more information,

Cheers,

Brian.

Hi,

Did you want me to throw this one in a low priority Jira so it isn't lost?

Cheers,

Brian.

The examples etc are misleading. We don't support 'JMSXGroupSeq' at all. I will remove references to it today.
