====== The intrinsincs of web.xml ======

I've messing around searching for someone who explains me clearly the intrinsics
of the configuration of the web.xml file and finally I've found something 
in a manual from oracle: 

http://download.oracle.com/docs/cd/E13222_01/wls/docs70/webapp/webappdeployment.htm

I attach here for the sake of not loose it: 

{{:java:webapp.pdf}}

And I don't want to loose the opportunity to to comment one thing: the issue of the
context parameters.

===== What Context Parameters Are =====

Context Parameters are this: parameters that the application --or a library, also 
known these days as **framework**-- can read from the ''web.xml'' file. 

Here is the syntax to define a context parameter: 

<code xml>
  <context-param>
  
     <param-name>user-defined parameter name</param-name>
     <param-value>user-defined parameter value</param-value>
     <description>optional description, just text</description>
     
  </context-param>

How can them be read: 

<code java>

javax.servlet.ServletContext.getInitParameter()
javax.servlet.ServletContext.getInitParameterNames()
