But I am still uncertain. Can this point to only jsp files? A java class? If there is a good example somewhere I would be thrilled if someone could send me a link to it.
this can point at any url that returns a schema - so you can implement either as a jsp or a servlet (or any number of other implementation technologies). i don't have any examples available of this particular scenario - but it should be similar to the pattern used in the press release example.
