Michael is right. A lot of people don't get this at first.
Similar to applets and EJBs, servlets don't have main() methods. They aren't
meant to run outside of a larger application context/container. They have an
API-specific set of methods that must be implemented for them to work correctly.
Some methods are optional, others are required to be overridden.
Like a Web browser calls an applet's init(), start(), stop() and destroy()
methods, a servlet container calls a servlet's init(), service() and destroy()
methods. You can put stuff in those methods, but you can't call them. The
container calls them at key times in the process of loading, running and
unloading applet and servlet (and EJB) classes. This API stuff is how the "life
cycle" of these types of objects is defined and controlled in a predictable,
standard, safe way.
A servlet container only calls a servlet's destroy() method when the server
shuts down or when you reload a servlet dynamically by changing its class. JRun
3.0 also exposes an API that allows you to ask the container to load() or
unload() other servlets, but this is a JRun specific feature and not commonly
used or needed (to my knowledge).
