It simply loads a class.</p> <p>Most JDBC Driver classes register themselves in their static initializers by calling <a href="http://download.oracle.com/javase/6/docs/api/java/sql/DriverManager.html#registerDriver%28java.sql.Driver%29" rel="noreferrer"><code>registerDriver()</code></a>.</p> <p><code>registerDriver()</code> is the real call that you hardly ever need to call yourself (unless you write your own JDBC driver).</p> <p>Note that in JDBC 4 you should not need <em>either of those</em> if your JDBC driver is up-to-date, as drivers can be found using the service location mechanisms instead (i.e. simply leave out that call and open your connection as usual). See the <a href="http://download.oracle.com/javase/6/docs/api/java/sql/DriverManager.html" rel="noreferrer">documentaton of <code>DriverManager</code></a> for details:</p> <blockquote> <p>The DriverManager methods <code>getConnection</code> and <code>getDrivers</code> have been enhanced to support the Java Standard Edition Service Provider mechanism. JDBC 4.0 Drivers must include the file <code>META-INF/services/java.sql.Driver</code>. This file contains the name of the JDBC drivers implementation of <code>java.sql.Driver</code>. For example, to load the <code>my.sql.Driver</code> class, the <code>META-INF/services/java.sql.Driver</code> file would contain the entry:</p> <pre><code>my.sql.Driver </code></pre> <p>Applications no longer need to explictly load JDBC drivers using <code>Class.forName()</code>. Existing programs which currently load JDBC drivers using <code>Class.forName()</code> will continue to work without modification.</p> </blockquote>
