            // using file based policy repository. so set the policy location as system property
            String policyLocation = (new File(".")).getCanonicalPath() + File.separator + "resources";
            System.setProperty(FileBasedPolicyFinderModule.POLICY_DIR_PROPERTY, policyLocation);
        } catch (IOException e) {
            System.err.println("Can not locate policy repository");
        }
