-/**
- * Servlet implementation class XacmlPdpServlet
- *
- * This is an implementation of the XACML 3.0 RESTful Interface with added features to support
- * simple PAP RESTful API for policy publishing and PIP configuration changes.
- *
- * If you are running this the first time, then we recommend you look at the xacml.pdp.properties file.
- * This properties file has all the default parameter settings. If you are running the servlet as is,
- * then we recommend setting up you're container to run it on port 8080 with context "/pdp". Wherever
- * the default working directory is set to, a "config" directory will be created that holds the policy
- * and pip cache. This setting is located in the xacml.pdp.properties file.
- *
- * When you are ready to customize, you can create a separate xacml.pdp.properties on you're local file
- * system and setup the parameters as you wish. Just set the Java VM System variable to point to that file:
- *
- * -Dxacml.properties=/opt/app/xacml/etc/xacml.pdp.properties
- *
- * Or if you only want to change one or two properties, simply set the Java VM System variable for that property.
- *
- * -Dxacml.rest.pdp.register=false
- *
