|

* <P>The basic service for managing a set of JDBC drivers.<br>
|
||||
* <B>NOTE:</B> The {@link <code>DataSource</code>} interface, new in the
|
||||
* JDBC 2.0 API, provides another way to connect to a data source.
|
||||
* The use of a <code>DataSource</code> object is the preferred means of
|
||||
* connecting to a data source.
|
||||
*
|
||||
* <P>As part of its initialization, the <code>DriverManager</code> class will
|
||||
* attempt to load the driver classes referenced in the "jdbc.drivers"
|
||||
* system property. This allows a user to customize the JDBC Drivers
|
||||
* used by their applications. For example in your
|
||||
* ~/.hotjava/properties file you might specify:
|
||||
* <pre>
|
||||
* <CODE>jdbc.drivers=foo.bah.Driver:wombat.sql.Driver:bad.taste.ourDriver</CODE>
|
||||
* </pre>
|
||||
*<P> The <code>DriverManager</code> methods <code>getConnection</code> and
|
||||
* <code>getDrivers</code> have been enhanced to support the Java Standard Edition
|
||||
* <a href="../../../technotes/guides/jar/jar.html#Service%20Provider">Service Provider</a> 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:
|
||||
* <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>When the method <code>getConnection</code> is called,
|
||||
* the <code>DriverManager</code> will attempt to
|
||||
* locate a suitable driver from amongst those loaded at
|
||||
* initialization and those loaded explicitly using the same classloader
|
||||
* as the current applet or application.
|
||||
*
|
||||
* <P>
|
||||
* Starting with the Java 2 SDK, Standard Edition, version 1.3, a
|
||||
* logging stream can be set only if the proper
|
||||
* permission has been granted. Normally this will be done with
|
||||
* the tool PolicyTool, which can be used to grant <code>permission
|
