[jboss-user] ClassLoading order

Hi, I am using a particular implementation of apache-poi for my web app. The jar is there in web-inf lib of my war deployment folder (server/<node-name>/deploy/<mywar>/WEB-INF/lib), I want to patch in my own classes (created in the same package structure as the poi class I want to patch). I have created a patch poi-patch.jar out of these new class files. Where do I place this jar/how do I ensure my classes are loaded in preference to apache-poi classes. Thanks. Warm Regards, Neha
