Context Init Parameters

The inits we saw are per servlet.

Context init parameters operate per web application. They are defined like:

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"
    "http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
<web-app>
  <context-param>
    <param-name>rmiregistry</param-name>
    <param-value>myrmi.jmvidal.cse.sc.edu</param-value>
  </context-param>
  <!--servlet elements here-->
</web-app>

and accessed using

//get the value of name
public String ServletContext.getInitParameter(String name);

//get an enum over all names
public Enumeration ServletContext.getInitParameterNames();
