i'll rename it to o.j.messaging.utilities. as far as i checked there were no other clashes: JMS code is in o.j.jms in 1.4 while JBM 2 code is in o.j.messaging.jms Both version use o.j.messaging.core but JBM 1.4 code is below "impl" subpackage while JBM2 is splitted in many subpackages I'll do a thorough check to be sure that there is no other class clashes than the util package View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4201467#...
