Hello all, I have a common problem that I'd like to be able to solve more cleanly than I do. I often have action beans that expose a piece of logic to several different types of callers. For example they may support the same call via AJAX to which they return JSON, and as a regular web request, to which they return HTML. Typically I will set up a different method on the action bean to handle each case and they will both call some shared internal logic to do the operation but return different resolutions with the results.
This is easily done except for two things: - how to handle errors in validation of input parameters - how to handle general errors in the execution of my action bean. In both cases I want my JSON methods to return JSON formatted errors and my HTML methods to return HTML pages displaying errors. The default behavior of Stripes is that my JSON methods all return HTML errors which, of course, horribly breaks the parser at the other end. For the validation case I tried implementing ValidationErrorHandler on my action bean. However this has to be done on a whole-bean basis - I then have to put inside there some kind of switch logic that differentiates the HTML cases from the JSON cases. This feels very unclean. For the general error handler the only solution I've found is to wrap every method call with an appropriate try / catch block explicitly and return the appropriate content back from it. None of this is very hard, but it has a real "square peg in round hole" feel to it. Does anybody know of cleaner solutions to handle this kind of problem? Will Stripes 1.5 offer anything new to help? Thanks for any suggestions!
