Hi,
Entity Bean is high end Persistence technology. Where as JDBC is a DB connectivity API. If you are aware of the 4 types of driver, Entity bean uses Thin (Type 4) driver for DB connection. In normal JDBC application manually transactions & security needs to be maintained. But using Entity Bean we can leave this work on EJB container which provides container services. This also increase the performance of handling database record as the server can cache the frequently accessed records.
As I mentioned earlier JDBC is DB connectivity technology which is used in Entity bean also but isolated in the configuration.
