Servlet Contexts
- Initial parameters can also be set up for the entire web application,
and not just for individual Servlets.
- Can be stored outside the compiled Servlets (in web.xml) and
changed at will.
- Each ServletConfig object has access to the application's
context parameters through a ServletContext object.
- Example: Give all Servlets in an application access to the web
administrator's email address, in the event of processing errors.
