Hello!

I am trying to create two JMS Topic independent sessions in two
different threads, and the second one fails (independently which one
is
run in second (I tried swapping launch order)), with following log
(see below).

What's wrong with this basic code?

thanks

NB: test program runs with WL7's weblogic.jar (servers are also WL7)
