Installation instructions:

Place the "labeler.class" file in $JAVA_HOME/jre/lib/pdsppi
Add "$JAVA_HOME/jre/lib/pdsppi" to your CLASSPATH environment variable.

Note: The application also uses the PDS Label parser, PDS/PPI Ruleset Processor,
IGPP classes (iggp.jar) and Javax Servlet (javax.servlet.jar).

You will need to download these Jar files as well.

Some examples:

Example ruleset to process a file.
Example ruleset for constants
Example template

A servlet that calls the Labeler to generate a response:

<%@ page language="java" contentType="text/html" %>
<%@ page 
	import="ruleset.Labeler" 
%>

<%
	ruleset.Labeler example = new ruleset.Labeler();
	example.setOutput(out);
	example.processItem("example.rul", "example.dat");
%>
