Hi, I've written the configuration File and when I try to load it, it 
throws an Exception. Thanks.

XMLConfigurator xmlconfigurator = new XMLConfigurator();
           File assertionConfigFile = new 
File(testDir+"/samlProfile-assertion-config.xml");
          
           if (!assertionConfigFile.exists()) {
               throw new Exception(
                       "Assertion config file for SAML XACML Profile 
does not exist: "
                               + assertionConfigFile.getAbsolutePath());
           }
          
           xmlconfigurator.load(assertionConfigFile);
