Hi!
The provided examples don't covered what I want. I have just a reach
client (made swing) who sends an object an expects a response from the web
server(tomcat). I want to know if it functionality is doable without any
configuration file but programatically. Also in the:
http://activemq.org/site/how-should-i-implement-request-response-with-jms.html
is written that you can use the MultiplexingRequestor but I didn't see any
example that use this class neither in server side nor in the client side. The
bigest problem for me is how should I write the server side in order to send a
message to the reach client.
Regards,
Florin

examples and use it on both the
client and server (at least until you get used to JMS). Failing that
use the JMS API on both ends.
this example has the client and server side...

(just separate them into 2 different spring.xml if you want)
