Often it is sensible to have the broker as an external running
application, so it is available for procuders / consumers in othe
Thanks! Slightly different question. Is there any reason why one
shouldn't use vm transport?

Hi,
you can activate the persistence by using the KahaDB persistence adapter (

I am looking at using ActiveMQ. When using vm transport is data
persisted on the disk or is it always in memory? For eg: if I send
message and want it to be persisted in case VM crashed after that. Can
I do that?

I'm new to ActiveMQ and I'm trying to tune a very simple queue setup which
I'm relocating from disk to memory-only (VM transport, embedded broker,
launched from Spring).
Versions below, but I game for changing them as needed:
ActiveMQ core 5.1.0
Spring core 2.5.6
I have about
spatcher.dispatch(md);
}
return null;

According to the comment, this copy is a feature of vm:// transport not a
bug :-)
The other copy is easier to find. When the message is consumed we instead
get a call to ActiveMQMessageConsu

Hi Rob. I call connection.setCopyMessageOnSend(false) on the producer and
consumer connection objects, and yes, the producer and consumers all use the
vm transport.
See my second post in this thread for sample code demonstrating the problem.
(Actually, I just noticed that in that code I have
Hi Ryan,
how are you setting copyMessageOnSend - and are the consumers using
vm://transport too ?
cheers,

Hi,
For JournalLockedException, include activeio-core-3.0-beta4.jar (you may
have different version of this) in your
