4.5. A JSP Compiled

Many implementations of JSP engines leave the Servlet source code that they create in a working directory. Under many engines this is an option that must be explicitly turned on, but it is usually a trivial task to enable.

Reading through the generated source code can be extremely useful in debugging problems that are not readily apparent in the JSP page. In addition, this source code can provide experienced Java developers with additional insight about the inner workings of the JSP implementation.
