Introduction

Jigsaw has an simple implementation of CC/PP, it's mainly a framework for CC/PP developpers. It is assumed that you are familiar with Jigsaw architecture, and that you have understand the configuration tutorial.

Here we describe the CC/PP framework available in Jigsaw, it is based on the "CC/PP exchange protocol based on HTTP Extension Framework" W3C Note.

Jigsaw provide a set of classes that developpers can use to build a CC/PP application:

org.w3c.jigsaw.ccpp.CCPPFrame

Should take replace the usual HTTPFrame

org.w3c.jigsaw.ccpp.CCPPRequest

A wrapper for the classic Request class, provide some CC/PP functionalities.

org.w3c.jigsaw.ccpp.CCPPWarning

the CC/PP Warning

org.w3c.jigsaw.ccpp.ProfileRef

The CC/PP Profile Reference

Writing a CC/PP application

If you want to write a CC/PP application you will need to write a new Frame that inherits from CCPPFrame and define the behaviour of the usual HTTP methods (GET, HEAD, PUT, ...).

    public class MyCCPPFrame extends CCPPFrame {

        /**
         * My CC/PP GET method.
         * @param request The request to handle.
         * @exception ProtocolException If processsing the request failed.
         * @exception ResourceException If the resource got a fatal error.
         */

        public Reply get(Request request) 
    	    throws ProtocolException, ResourceException
        {
            CCPPRequest ccpprequest = getCCPPRequest(request);
            
            Reply reply = createDefaultReply(request, HTTP.OK);

            ProfileRef[] refs = ccpprequest.getProfileReferences();
 
            // ...

            return reply;
        }

    }
