Subject Re: [Logging] : Can commons.logging be used without log4j
Date Wed, 11 Aug 2010 20:10:09 GMT

I am using instead of log4j.xml. 

Will RepositorySelector  concept still work? What changes I should make 
into this method?

   private static void loadLog4JConfig(ServletConfig config,
                                       Hierarchy hierarchy)
                                            throws ServletException {
        try {
            String log4jFile = "/WEB-INF/log4j.xml";
            InputStream log4JConfig =
            Document doc = DocumentBuilderFactory.newInstance()
            DOMConfigurator conf = new DOMConfigurator();
            conf.doConfigure(doc.getDocumentElement(), hierarchy);
        } catch (Exception e) {
            throw new ServletException(e);

This isn't true.  Log4j allows for defining and using multiple log
configurations in a single JVM.  This is accomplished by using a
RepositorySelector to manage the multiple log hierarchies.  See for a web
container example.
