code: public InputStream getConfPathXmlStream(String filePathName){
       int i = filePathName.lastIndexOf(".xml");
       String name = filePathName.substring(0, i);
       name = name.replace('.', '/');
       name += ".xml";
       return getConfStream(name);
    }
docs: same as getConfPathXmlFile
  @param filePathName
  @return the InputStream intance
