Re: Object Caching [Was: JDBC Class Abstraction]

I'm doing a caching on the client side. I have made a TableModel to keep 100rows in a Vector. (MouseoverEvent in the table gets it's data from the Vector). If the user asks for a row outside this vector I'm doing another 100 row fetch to the serverside ResultSet.
