How do I have the JSP-generated servlet subclass my own custom servlet class, instead of the default?

One should be very careful when having JSP pages extend custom servlet classes as opposed to the default one generated by the JSP engine. In doing so, you may lose out on any advanced optimization that may be provided by the JSPengine.
