Class DynamicDriver

  • All Implemented Interfaces:
    java.sql.Driver
    public class DynamicDriver
extends java.lang.Object
implements java.sql.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.
