so this means i have to manually "turn off" the passivation of my SFSB via
bean managed transactions. but i suppose this means a performance loss :(.
is this problem another issue of the bug mentioned above and so the only
solution is turning off the passivation mechanism?
further, til now whenever i tried to make some kind of manual transaction in
my beans i always got the error that the container is taking care of the
transactions and bean managed control (transactions) is not allowed. maybe
you can tell me what i have to change to be able to add transactions to my
and even further, is there the possibility to turn off the passivation for
SFSB at all in geronimo? like some entry in a deployment descriptor
"passivation=false" ?
thanks a lot for helping,
