Hi Al,
It looks like we're getting to the home stretch of your application.
As Andreas said earlier, setUserConfig() can throw an exception which,
regardless of whether or not it actually happens, must be handled. You can
fix this by placing the call inside of a try/catch as follows:
try {
//your call goes here -- fopFactory.setUse...
} catch (SAXException e) {
System.out.println(e);
}
Hope that helps!
