Question: JDBC Type 4 drivers are implemented
A. using a mixture of java code and custom C code, linked using the JNI
B. using a proprietary database vendor protocol to communicate with the JVM
C. in pure java
D. using generic networking APIs through TCP/IP sockets. At the server-side, a middleware application translates the generic APIs to the database-specific calls required
I answered as C. Is this correct?
Pls view info at http://www.cariboulake.com/techinfo/jdbc_driver_types.html I'm sure many of us here has use classes12.zip (the JDBC driver for Oracle). Now, is that type 3 or 4?
