<Li> This driver is platform dependent . </Li> <Li> This driver supports all Java applications except applets . </Li> <P> The JDBC type 3 driver, also known as the Pure Java driver for database middleware, is a database driver implementation which makes use of a middle tier between the calling program and the database . The middle - tier (application server) converts JDBC calls directly or indirectly into a vendor - specific database protocol . </P> <P> This differs from the type 4 driver in that the protocol conversion logic resides not at the client, but in the middle - tier . Like type 4 drivers, the type 3 driver is written entirely in Java . </P>
