I use the rule of thumb that three different (!) layers must use an interface before it's realistic to call it "stable". > (or that the "real" exceptions > must be catched and converted into an "acceptable" one, which looses > information). Converting to an "acceptable" one can encapsulate: SAXException does this, as does InvocationTargetException. A stack of "this error caused that one caused that one ..." is often much more helpful when diagnosing a problem than an root cause. Converting often actually _adds_ information ... like why the error couldn't be recovered. Keep in mind that a normal behavior for exceptions is catching and recovering! - Dave xml-dev: A list for W3C XML Developers. To post, mailto:xml-dev@i...
