Class DriverManagerAccessor

java.lang.Object

org.apache.taglibs.standard.tag.common.sql.DriverManagerAccessor

public class DriverManagerAccessor
extends java.lang.Object

Class that provides access to DriverManager.

DriverManager is not compatible with a modular environment, as it does no allow direct access to driver classes that the callers class loader cannot load. This class allows access to DriverManager by being forced into a cl that does have access and then invoking the DriverManager methods.

This is a horrible hack.
