ActiveMQ - can it do tasks

[agatone <zo...@gmail.com>]

Hello,

As I'm from non-Java world trying to get into this Java stuff it's quite
hard to understand all JAVA stuff concepts. B/c of that I have problems
understanding ActiveMQ manual (mostly i don't know how to define search
terms that would get me something useful) so I decided to ask here.

Basically I'd like to know only if these things are possible and what term
to search for in manual (or google) so I can read about it.

Can ActiveMQ invoke code (written: C#, JAVA, PHP etc) when certain message
is received or in any other way do something when a message is received?

I don't want to hang consumer on the activemq so it waits for the msg
itself.

Thank you

Its normally just a couple of lines of code to write a consumer

If you are averse to writing code; write a single program using a
single consumer which takes the String of the queue to use and the
name of the program to run; then you can fire off any executable you
wish when a message comes in.

Ok, so I'll have to code durable consumers for every language i'll use and
foreach topic , and it will be invkoing things.
That kinda sounds lots of code with those 1000  :|

So you'd write programs in some language (C#, Java, PHP) which consume
messages from a queue - and your program would invoke whatever code
you like.

Typically ActiveMQ itself doesn't invoke things - your consumer
program consumes messages then invokes code.

You might have 1000 programs running on hundreds of servers - with a
single ActiveMQ broker dispatching messages to them for example.
