Hello, I am running into a problem with classloading as I try to run 2 web- application through a debugger. The two projects have overlapping copies of the same class files (ie, both projects use Class A). The problem is that when Tomcat (4.0.6) is run through my debugger, the WEB-INF/classes are not loaded by org.apache.catalina.loader. WebappClassLoader. They are apparently loaded by the system classloader. So my Class A instance is shared between my 2 web-apps when in fact they should each have their own instance. Run outside the debugger, the WebappClassloader does its job & both web-apps get their unique copies of class A. Here is what Class A has to say about who's loading it:
Outside the debugger: --------------------- Class A's ClassLoader's class is [class org.apache.catalina.loader. WebappClassLoader] ClassLoader's parent class is [class org.apache.catalina.loader.StandardClassLoader] ClassLoader's parent class is [class org.apache.catalina.loader.StandardClassLoader] ClassLoader's parent class is [class sun.misc.Launcher$AppClassLoader] ClassLoader's parent class is [class sun.misc.Launcher$ExtClassLoader] Inside the debugger: -------------------- [EMAIL PROTECTED] ClassLoader's class is [class sun.misc.Launcher$AppClassLoader] ClassLoader's parent class is [class sun.misc.Launcher$ExtClassLoader] Is there a way that I can prevent the WEB-INF classes from being loaded by the System classloader? I know this was part of the servlet spec as the Tomcat documentation notes: "The web application class loader diverges from the default Java 2 delegation model (in accordance with the recommendations in the Servlet Specification, version 2.3, section 9.6). When a request to load a class from the web application's WebappX class loader is processed, this class loader will look in the local repositories first, instead of delegating before looking." So why isn't WebbappClassLoader loading the WEB-INF/classes when debugging? Thanks in advance for your help!
