[Kroeksak Kongman]

To make an XML parser available to your web applications, you have several options:

*       To utilize an XML parser in a single web application, simply include the 
parser's JAR files in the /WEB-INF/web.xml directory of that web application. This 
will work, no matter what parser might be used by Tomcat 4 internally, or by other web 
applications running in the same instance of Tomcat 4. 

Please would you tell me, 

    how to include the parser's JAR files in the /WEB-INF/web.xml ?
