Finally I got the server running...thanks again for your patience and 
your help! but one more thing would be interesting to know...is there an 
advantage if i run the openJMS server within geronimo or if I use a JMS 
connector or is just a question of design!? i mean is there any 
advantage concerning performance of both geronimo and openJMS? thanks a lot!
