My project has to use Xerces-J 2.8 and I have Xerces-J.2.8.jar under my
project /WEB-INF/lib
How can I make my project invoke /WEB-INF/lib/ 2Xerces-J.2.8.jar without
changing system's classpath? |

that are loaded by the web application's parent classloader.
It should not be put in the java ext library path, $CLASSPATH,
web/app servers common lib, domain lib and maybe more. If
other apps need to use this jar, they should have their own.

WebLogic allows you to specify from which classloader you want to load the
jar. |

Configure your appserver so that the web app classloader will only ask
the parent classloader if it can't find a resource by itself. Note that
that is the opposite of the java classloading delegation protocol.
