And it requires further refactoring. The static "getSecurityService" would need to move to a different class. SecurityService securityService = SecurityService.getSecurityService(); If Security is enabled then the above returns an instance of IntegratedSecurityService. If Security is disabled then the above returns an instance of NullSecurityService. All of the methods return false, null or if return type is void then the method is simply empty. JIT will eventually remove the calls to methods that are empty so runtime gets even faster. - Kirk ----------------------------------------------------------- This is an automatically generated e-mail.
