Class DynamicDriver

java.lang.Object

org.tentackle.sql.DynamicDriver

All Implemented Interfaces:

Driver

public class DynamicDriver
extends Object
implements Driver

Loads a JDBC driver dynamically at runtime via a URL.
Because DriverManager will refuse to use a driver not loaded by the system-classloader, we must wrap the URL-loaded driver by such a class.
