As the name suggests Balana(the fortress) is a powerful entitlement engine to externalize authorization from your applications. With it's modular architecture you can easily develop a fully fledged entitlement solution in no time.

Specifications Supported by Balana

Balana supports the XACML 3.0, 2.0, 1.1 and 1.0 specifications.

            // Using file based policy repository. so set the policy location as a 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");
        }
        // Create default instance of Balana
        balana = Balana.getInstance();
    }
