java.lang.Object
- org.apache.derby.jdbc.AutoloadedDriver

All Implemented Interfaces:

java.sql.Driver
```
public class AutoloadedDriver
extends java.lang.Object
implements java.sql.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();

    
        
```
