Message Priority Question

Hi, 

 

I am wondering if it's possible to change a Message priority. I know
it's a JMS provider specific property, but can we change the priority of
a message even by JMX interface (or somehow)? And if its possible then
what will be the impact on a message which will have higher priority
then other messages in the Queue/Topic.

 

Thanks!

 

Vik

We don't currently support message reordering based on priorities; we
recommend using selectors for fine grained priority traffic shaping

Thanks James, 

And is it actually going to affect the processing order of a high
priority messages, in reference to the lower priority messages? i.e.
higher priority messages will be given to the consumers first. 

Thanks!

You can set the priority on a message using the MessageProducer API

Once you've sent a message you can't update it; you can pull a message
off a queue and send it back on again if you want
