Using the Xalan XSL Processor for Java with Java Servlets

In order to test and run the cpl_graphic.xsl file using the Xalan processor, 
you must:

- Make sure you have a web server that is able to run Java Servlets.

- Place the XHTMLGenerator.class in the "servlets" directory of your web
server or any other directory that will allow it to run.

- Place the xsltester.html file in the directory of your choice(as long as it is publicly
available).

- In the base directory that xsltester.html is in, create the following directories:

	- xsl - place the cpl_graphic.xsl document in there.
	- css - place the global.css file in there.
	- js - place the global.js file in there.
	- images - place all the gif and jpg files in there.
	- help - place the files name address-switch.html, location.html, lookup.html,
		    etc. in this directory.

- Open the "path.cfg" file and without any spaces or returns, put in the name 
of the directory where you have placed the cpl_graphics.xsl file.  It should be 
"http://<domain plus any directories that follow>/xsl/".  Basically, this is the 
URL location of the cpl_graphic.xsl file.  Don't forget the last "/" and DO NOT 
include the name "cpl_graphic.xsl" at the end.  Save this path.cfg file into the 
same directory that you have put XHTMLGenerator.class(this is very important).

- Place the Xalan.jar and Xerces.jar files in the "lib" directory of the web server 
or any other directory that is in the CLASSPATH.

- Open the xsltester.html page in a web browser and type in the full path URL of 
the CPL script you wish to view graphically.

- Click transform.
