When Java first came out, this was a useful driver because most databases only supported ODBC access but now this type of driver is recommended only for experimental use or when Disadvantage: (1) The ODBC Driver needs to be installed on the client machine. (2) It’s a not a purely platform independent because its use ODBC which is depends on native libraries Another way to register drivers is to add the driver classes to the jdbc.drivers property. http://depthvision.net/jdbc-driver/difference-between-type1-and-type-2-jdbc-drivers.html

They install inside the Java Virtual Machine of the client. this driver is specific to a particular database. These types of drivers are slowest of all types. Written completely in Java, type 4 drivers are thus platform independent.
It tests the drivers by calling the method Driver.connect on each one in turn, passing them the URL that the user originally passed to the method DriverManager.getConnection. Some distinctive characteristic of type 2 jdbc drivers are shown below. This causes the portability issues. Class Connection Type 4 Driver Native API must be installed in the Client System and hence type 2 drivers cannot be used for the Internet. 2.
If the middle-tier server can in turn use Type1, Type 2 or Type 4 drivers.Type 3: All Java/ Net-Protocol Driver Advantage 1. Jdbc Driver Oracle Sun provides a JDBC-ODBC Bridge driver by “sun.jdbc.odbc.JdbcOdbcDriver”. Thus the client driver to middleware communication is database independent. Can interface to multiple databases – Not vendor specific.
The JDBC-ODBC Bridge that comes with JDK 1.2 is a good example of this kind of driver. http://www.jdbc-tutorial.com/jdbc-driver-types.htm Recommended for You © 2017, O'Reilly Media, Inc.

JDBC Drivers Before you can use a driver, it must be registered with the JDBC DriverManager. It is suitable for the web. 3. Jdbc Odbc Bridge Is Multithreaded Specific ODBC drivers are not always available on all platforms; hence, portability of this driver is limited.
The middleware layer added may result in additional latency, but is typically overcome by using better middleware services. The JDBC-ODBC Bridge is use only when there is no PURE-JAVA driver available for a particular database. The type 1 driver is not considered a deployment-level driver, and is typically used for development and testing purposes only. check over here You don’t need to install special software on the client or server.
Disadvantages 1. Different applications have different needs. Using ODBC, requires configuring on your system a Data Source Name (DSN) that represents the target database. and/or other countries.
The Java.sql package that ships with JDK, contains various classes with their behaviours defined and their actual implementaions are done in third-party drivers.
