http://issues.apache.org/bugzilla/show_bug.cgi?id=36397 ------- Additional Comments From [EMAIL PROTECTED] 2005-08-30 06:58 ------- After I gave it a little more thought, using recursive property references is even more restrictive, because you must define ALL properties on ALL branches so that for instance you cannot skip 'jta.UserTransaction' if you go on the JDBC branch. All right, I'll restate my case, because I incline to the directives again. There is one user level property file "custom.properties" that can be read, saved, reloaded, aso. It contains high-level properties that require customization: db=postgres user=foo password=bar On the other hand, there is a property TEMPLATE file "default.template" which used conditional directives and is integrated with commons-configuration by means of reader: CompositeConfiguration config = new CompositeConfiguration(); FileConfiguration customConfig = new FileConfiguration("custom.properties"); FileConfiguration defaultConfig = new FileConfiguration(); PropertyTemplate defaultTemplate = new PropertyTemplate("default.template"); defaultTemplate.addConfiguration(customConfig); // needs it to evaluate the directives defaultConfig.load(defaultTemplate.getReader()); // the reader implements the directives, defaultConfig "sees" a regular property stream. config.addConfiguration(customConfig); config.addConfiguration(defaultConfig); The thing here is that "default.template" is never seen by the user, it's only changed at design time and is stored together with the classes so that you wouldn't need to save or reload it. It's main purpose is to hide from the user Java internal details like JDBC drivers, hibernate properties, aso. I need to implement a similar scheme in the ant build (for generating deployment descriptors), so having the PropertyTemplate as a stream makes it easier to integrate with the "property" task in ant. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
