ok, don't use an ejb for this...
how about simple external java class (implemented as a startup class or whatever)
which is
allowed to handle threads...

Actually, I should have been more specific. In my case, Bean A is a legacy
component(Neither any assumptions nor any tampering Bean A). So, I feel that the
resources pointed to, may not be applicable for this. As Bean B, do I have any other
options than busy-waiting ??

You could try this:

or you could use JMS:
let Bean A notify Bean B of any state changes
so indirectly Bean A activates Bean B
How about this?

Hi Fabian,
The scenario goes like this:
Bean B invokes a method on Bean A (B is ignorant of the state of A)
Bean B should try this repeatedly until the state of A is changed (to
a state favourable for servicing Bean B's request).
I know it is a performance overhead, but, thatz how the business logic
goes. For this case, I'm worried more abt achieving this rather than the amount of
time Bean B is blocked.
Hope this makes my point clear!
Regards,
Sriphani.
