Question

The Oracle JDBC tutorial says

In previous versions of JDBC, to obtain a connection, you first had to
initialize your JDBC driver by calling the method Class.forName. This
methods required an object of type java.sql.Driver. Each JDBC driver
contains one or more classes that implements the interface
java.sql.Driver. The drivers for Java DB are
org.apache.derby.jdbc.EmbeddedDriver and
org.apache.derby.jdbc.ClientDriver, and the one for MySQL Connector/J
is com.mysql.jdbc.Driver. See the documentation of your DBMS driver
to obtain the name of the class that implements the interface
java.sql.Driver.

Any JDBC 4.0 drivers that are found in your class path are automatically loaded. (However, you must manually load any drivers
prior to JDBC 4.0 with the method Class.forName.)

But when I remove Class.forName it gives an error No Driver found. I am using ojdbc14 driver. How do we implement connection without Class.forName?

Answer 1

Look closely at the JDBC version. The article says that it’s introduced in JDBC 4.0 (Java 1.6).

However, ojdbc14 is a JDBC 3.0 (Java 1.5) driver.
