I just double checked this on a clean install from the jbossesb-server 4.2 GA download and it worked well. (ant deploy, ant runtest in the business_rules_service quickstart).
Is it possible that you had already issued an "ant deploy-jms-dests" before you did "ant deploy". If so then please perform an "ant undeploy-jms-dests" and then retry "ant deploy". There are 2 modes of runtime operation standalone/bootstrapper and .esb archive and it sounds like you may have mixed the two slighly. The readme.txt has the details.
That was it. I did "ant deploy-jms-dests" before "ant deploy". "ant undeploy-jms-dests" did the trick. Things are working just fine now.
Thanks for the quick response!!!
