JPL is a simple Servlet 2.2 (or later) web application containing its own copy of jpl.jar and a couple of servlets which call SWI-Prolog (see JPL/WEB-INF/classes) JPL.war is JPL in the form of a "web archive" To deploy under Tomcat, copy either JPL or JPL.war into Tomcat's webapps folder and restart Tomcat. Then visit the application's default ("welcome") page, e.g. http://localhost:8080/JPL with a web browser. ---- Paul Singleton February 2004
