[jetty-users] Recommended database resident message queueing system? JMS

[Nick Fenwick <neek@xxxxxxxxxxxxxxx>]

Hi all,

I'm fishing for ideas.  I currently have a 'queue' thread started by a 
load-on-startup servlet, which listens to a ArrayBlockingQueue, so other 
threads can push objects onto the queue and the 'queue' thread picks 
them up and acts on them.  It's basically an inter-thread messaging system.

I now want to make the 'queue' database transaction dependent, so if a 
rollback of the transaction is done, it also rolls back the queue event 
objects.

This seems to be what JMS would bring to the table, probably using 
ActiveMQ.  However, it seems quite a complicated framework to bring into 
my project at this stage.  I'd rather not have to run the ActiveMQ 
message broker as a separate thread, and all the system resources that 
would entail, given that all my clients of the MQ would be local.  From 
a glance at ActiveMQ, it seems to require this out-of-process broker.

Would anyone recommend another queued event system, like ActiveMQ, that 
would let me do this all in-process to my main app?  I currently use 
MySQL, but anything that works over JDBC should be fine.  I use 
Hibernate extensively but I wouldn't expect this queue system to require 
that at all.

Thanks for any pointers.
Nick
