because jackrabbit uses an internal cache that you cannot disable.
so if one instance modify the physical storage, the other instance will
not be aware of the change and use wrong data and possibly corrupt the
data integrity

Hi,
On the "Model 1: The (Web-) Application Bundle HOWTO
<http://incubator.apache.org/jackrabbit/arch/deploy/howto-model1.html>"
web page, there is a note: "remember that two Jackrabbit instances
should never read from/write to the same physical storage. This setup
is not supported and will lead to corrupt data."
Can anyone explain why there is such an restriction? Why two sessions
from the same Jackrabbit instance could read from/write to the same
physical storage, but not two sessions from two Jackrabbit instances?
I appreciate your input.
thanks,
Richard
