I have a quick question I hope someone out there can help me with.
Do any of the EJB servers out there support "eventing" back down to the client.
For instance if a client application had a grid displayed with x rows of data,
maybe each being an EJB object, or the grid as a whole was an EJB object, is
there any way to "register an interest" on any updates to the underlying data,
i.e. when another process updates the data, we want to know about it, and keep
the data shown in-sync for all clients. Would this functionality have to be
hand-coded, or is there support in any commercially available EJB servers??
I would prefer something along the lines of the Corba event channel "push"
mechanism.
Hope it's clear what I am asking here.
Regards,
Matt
