Normally the data that is being cached is a Vector of information spanning
multiple entities say orders and customers.
So caching your entity beans will only give you some advantage ( if you are
using entity beans to read data ). You could also use a stateful session
bean with the Vector as an instance variable on it. Then the method on your
sesion bean would use the Vector if it's already been established.
