The exceptions it gives are the ones I'd expect - no overriding JRE classes, servlet classes ignored, use of the endorsed override mechanism. I'm really more interested in the non-exceptional case of simply loading my application classes and those from third-party jars such as Apache Commons packages. > > > I need confirmation that that second part of the documentation > > is in error (or not, of course). > > All parts of the classloader doc appear to be correct to me, also > confirmed by a quick glance at the code. I don't see how that can be the case: "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 ... All other class loaders in Tomcat 6 follow the usual delegation pattern." But then it says, this, which describes a different search order: Bootstrap classes of your JVM System class loader classes (described above) /WEB-INF/classes of your web application /WEB-INF/lib/*.jar of your web application $CATALINA_HOME/lib $CATALINA_HOME/lib/*.jar They can't *both* be right. --Pete > > You might want to look at the API spec for the class of interest: > http://tomcat.apache.org/tomcat-6.0- > doc/api/org/apache/catalina/loader/WebappClassLoader.html > > - Chuck > > > THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE > PROPRIETARY MATERIAL and is thus for use only by the intended > recipient.
