I see you latest comment, but the same error for DocumentBuilderFactorImpl: org.apache.xerces.jaxp.DocumentBuilderFactoryImpl Information Repository cache version: org.apache.xerces.jaxp.DocumentBuilderFactoryImpl(12fa617).ClassLoader=null ++++Null CodeSource Implemented Interfaces: ### Instance0 via UCL: [EMAIL PROTECTED] I guess it means the class is loaded, since searching for com.foo.BarClass results in different message: "Not loaded in repository cache". But where is this class loaded from? ---------------------------------------- I am guessing the problem is something along the lines: - JBoss starts up and loads it's own xmls using xerces parser - This causes some JRE-wide setting that makes all DocumentBuilderFactories use xerces parser (not sure about what goes on behind the scenes here) - my application is loaded, it starts to initialize Spring (spring.jar inside my war) - Spring tries to load the xml files for configuration - Because of the setting in the seconds step, it tries to use xerces parser - My war classloader does not see the xerces parser (why?) - OR my war classloader sees the xerces parser but for some reason the code expects a different type....ok, I'm a bit lost here... Question regarding the jboss-web.xml "tweak" - my war classloader still sees the universal classloader classes, if those classes do not exist in the war, right? It has to, otherwise I would have to for example include servlet API.jar in my war? Thousand thanks fot the fast replies :) I have to go to a meeting now but will be back to fighting with this problem later.
