Tomcat already has a form of this capability: org.apache.catalina.loader.VirtualWebappLoader If you declare this in the className attribute of a <Loader> element nested inside the <Context> of interest, you can specify additional directories to search for class references. It exists in all supported Tomcat levels, but is only documented in Tomcat 7: http://tomcat.apache.org/tomcat-7.0-doc/config/loader.html#VirtualWebappLoader_Implementation - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
