Hi,
first of all m a newbie to java,so please ignore any foolish doubts...

i want to develop a simple messaging Jms application in eclipse. i ve already configured JBOSS with ActiveMQ and tested the build process by referring to the below link.
http://activemq.apache.org/integrating-apache-activemq-with-jboss.html

Now, i m clueless of what to do next...i need to know:

1. how to start developing any simplest application on eclipse.
2. how to link jboss with eclipse(if needed).
or how to call it from outside.
3. how to use ActiveMQ.

Please help me as i m stuck.suggestion are always welcome.
