So we should increase everyone's path length because one person does something completely counter to the Java API intent? > Unfortunately, the Jsp 2.0 specification does not address > this issue. Nor should it, since this is a Java API issue, not a JSP spec one. > The print(Object o) is not documented to throw a > NullPointerException, only an IOException. >From the API spec: "public class RuntimeException extends Exception "RuntimeException is the superclass of those exceptions that can be thrown during the normal operation of the Java Virtual Machine. "A method is not required to declare in its throws clause any subclasses of RuntimeException that might be thrown during the execution of the method but not caught." NullPointerException is merely the most common of the large set of RuntimeException subclasses. - Chuck --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
