Class MessageHandler

java.lang.Object

org.qbroker.jms.MessageHandler

All Implemented Interfaces:

com.sun.net.httpserver.HttpHandler

public class MessageHandler
extends java.lang.Object
implements com.sun.net.httpserver.HttpHandler

MessageHandler implements HttpHandler for http servers. It handles HTTP requests and converts them into JMS messages before passing them to the assigned message service as requests. Once a response message is back, it converts the message to JSON content and sends the content back to the HTTP client as the response. Therefore, MessageHandler is the frontend and the gateway for message services. It is responsible for transformations between HTTP requests/responses and JMS messages.

N.B. The name of the handler is supposed to be same as the substring of the context path starting from the 2nd character (after the beginning "/").
