Hi.
Is it possible to change JMS queues semantics to Last In, First Out
(ie.
stack)? Would it be difficult to patch ActiveMQ sources to achieve
this?
Another solution to our problem is using priority queues. But ActiveMQ
doesn't support priorities. Only Oracle's AQs support this...
A bigger picture: we are using JMS for grid computations, task have
subtasks
and subtasks have to be computed first. It would be nice to have a
general
solution for this using JMS.

Nice idea! Priorities for messages on Queues are really hard to
implement - but a potential option would be to have different priority
Queues - that level of granularity is a lot easier - I'll investigate
it.
The LIFO does seem a little wacky though.
