- * This interface is implemented by services in order to pass
- * configuration information to a servlet when it is first loaded. A
- * service writer implementing this interface must write methods for the
- * servlet to use to get its initialization parameters and the context
- * in which it is running.
- *
- * <p>The ServletConfig interface can also be implemented by servlets.
- * (GenericServlet does this.) When implemented by a servlet, the
- * methods in the interface make getting the configuration data more
- * convenient. For example, a servlet could implement
- * getServletContext by writing,
- *
- * <pre>
- * public ServletContext getServletContext() {
- * return getServletConfig().getServletContext();
- * }
- * </pre>
- * making access to the servlet's context object a single method
- * invocation (a call to <code>getServletContext()</code>).
