Good suggestions, Christian. I also recommend Spring JMS. Filip, here are some items I wrote about using Spring JMS with ActiveMQ that many folks have found useful: Using Spring to Send JMS Messages: http://bsnyderblog.blogspot.com/2010/02/using-spring-jmstemplate-to-send-jms.html Using Spring to Receive JMS Messages: http://bsnyderblog.blogspot.com/2010/02/using-spring-to-receive-jms-messages.html Tuning JMS Message Consumption In Spring: http://bsnyderblog.blogspot.com/2010/05/tuning-jms-message-consumption-in.html Hope it helps.
