Hi Patrick See the topic "log4j configuration via XML SOLVED" in this mailing list and the following from Alan Pearlman Spencer:
***************************************3 Hi Again, Tomcat, in it's batch file, has it's own CLASSPATH. It creates a ClassLoader for each webapp. It used all jars in lib directory and the classes directory. The problem you are seeing is that the ClassLoaders are in a tree structure. TOMCAT_CLASSLOADER WEBAPP_X_CLASSLOADER WEBAPP_Y_CLASSLOADER Take a look at the documentation for java.lang.ClassLoader for info on this. If a class A is loaded in WEBAPP_X_CLASSLOADER and it tries to load another class B (or resource) it first looks in WEBAPP_X_CLASSLOADERs classpath and then goes to the parent TOMCAT_CLASSLOADER. If B is not found in WEBAPP_X_CLASSLOADER, but is found in TOMCAT_CLASSLOADER and it then in turn tries to load another class or resource C it can only "see" TOMCAT_CLASSLOADER, so it does not have access to the WEBAPP_X_CLASSLOADER classpath. I think in your case: Servelt loaded in WEBAPP_X_CLASSLOADER XML file loaded in WEBAPP_X_CLASSLOADER XML parser loaded in TOMCAT_CLASSLOADER DTD searched for in TOMCAT_CLASSLOADER and not found. It probably makes sense to put the log4J.jar in the TOMCAT_CLASSLOADER's classpath... **************************************** I have copied the log4J.jar in %TOMACT_HOME%/lib then it worked.

I use VisualAge 4.0 if someone could explain me what i have to do for running the XTest class !!!!
