I want to build a generic exception handler which can be reused in any java j2ee applications.
I have java application which is communicating with other 3rd party applications like webservices, webmethods , etc from where we are getting an errorcode which will be used in our java application to do a lookup to get the respestive error message from the resource bundle. Please clarify in such case how I can go with a generic exception handler which will be build separately and will be integrated with Java applications to handle the exceptions and errors.An excellent example of why a universal exception handler wouldn't work.
At some point a call tree looks like A->B->C, where C (or beyond) that is where your communications problem occurs. The impact of that depends on the application.
For example if a user types in a url (at A) and the server (C) fails to resolve it then that is a user problem.
However if nightly batch process expects to download an update file every night from one location and it can't connect then that is an operations error (or notification/alert.)
