java.lang.Object
  org.ChinaVO.FITSManager.Util.DriverShim

All Implemented Interfaces:

java.sql.Driver

public class DriverShim
extends java.lang.Object
implements java.sql.Driver

a proxy driver to trick the security mechanism of driver manager.

example:
String strDrv = ss.getStringValue("config/database/driver",
"org.apache.derby.jdbc.EmbeddedDriver");
URL url;
try {
// url = new
// URL("file:/D:/Program Files/Develop/Java/eclipse/./derby.jar");
File f = new File(ss.getStringValue(
"config/database/driverFileURL", "./derby.jar"));
url = f.toURL();
} catch (MalformedURLException e) {
e.printStackTrace();
url = null;
}
URLClassLoader ucl = new URLClassLoader(new URL[] { url },
DBOperator.class.getClassLoader());
Driver drv = (Driver) Class.forName(strDrv, true, ucl)
.newInstance();
DriverManager.registerDriver(new DriverShim(drv));
