Class AutoloadedDriver

java.lang.Object
org.apache.derby.jdbc.AutoloadedDriver
All Implemented Interfaces:
Driver
public class AutoloadedDriver extends Object implements Driver
This is the dummy driver which is registered with the DriverManager and which is autoloaded by JDBC4. Loading this class will NOT automatically boot the Derby engine, but it will register this class as a valid Driver with the DriverManager. Instead, the engine boots lazily when you ask for a Connection. Alternatively, you can force the engine to boot as follows: 
 Class.forName("org.apache.derby.jdbc.EmbeddedDriver").newInstance();

 // or

    new org.apache.derby.jdbc.EmbeddedDriver();
