ServletConfig
Synopsis
Interface Name: javax.servlet.ServletConfig
Superinterface: None
Immediate Subinterfaces: None
Implemented By: javax.servlet.GenericServlet
Availability: Servlet API 1.0 and later
Description
Servers use ServletConfig objects to pass
initialization and context information to servlets. The
initialization information generally consists of a series of
initialization parameters (init parameters) and
a ServletContext object, which provides
information about the server environment. A servlet can implement
Servlet-Config to allow easy access to init
parameters and context information, as
GenericServlet does.
