Is onMessage() thread safe?

When new message is received, then wl uses MDB from the pool, does this mean that
MDB are thread safe? More specific, do we need to use "synchronized onMessage"
method and is is safe to use?
Thanks
Mike

Yes. A consumer's onMessage() will not get called again
until the previous call returns.

Thanks for your reply Tom,
This means it is safe to remove synchronization from onMessage() method and weblogic
will take care of neccessary synchronization.
