You should read the API to know what onFailure and onError convers (and what are their role in the request). As long as success is executed, you should handle your server response from there. This is so, because return values and error handling should not be limited to a standard since there can be as many different implementations as there are types of responses. You may consider using a general purpose response handler for your requests if you plan on using the same implementation in your return value (which is a good idea by the way). For instance, try looking at Ajax.Responders to register a global callback function. In any case, if you only want to handle one kind of response the way you do, it is clear that onFailure, and onError are not appropriate to warn the user about that kind of failure, as they should be used only if there is a problem with the returned value itself (i.e. a malformed XML document for instance) or if the script/server is unavailable for the moment. If onSuccess is called, it means that the request has successfully been executed, regardless of if the script encountered an error or not. If you are using JSON, you may consider having a value 'errorCode' and 'errorMsg' (or similar) in your response. If errorCode == 0, then the request was successful. If you are using XML, you may consider using a tag such as <error> to enclose information about exceptions, etc. The benefit of having a general error handler is that errors may be catch and process in a cohesive way. Which means that if you change the way you want to handle errors, you will not find yourself refactoring all your code to compensate for the inconsistencies. If you are using XML, you may consider Rico (at http://www.openrico.org/) which allows you to register XML tags to elements (that will be automatically updated) or objects (that will be called with the node as parameter).
