| | | Business Delegate | Business Delegate 2004-04-16 - By Ricardo de Souza Moura
Back
I would like very much. thank you.
But I was thinking about construct my Business Delegate(BD) not like a EJB.
The BD would be a normal class. therefore my web tier don't need to worry
about look up or RemoteException for example. Only my Bd would need to worry
about this. is it OK ? Do you agree ?
About to do cache I have some doubts.
My ServletContainer an my EJBContainer are in two differents machines. If
only the EJBContainer stop what happen with my cache at the ServletConainer
? it won't work anymore, will it ?
