Web Sockets Notifications

The JSON-RPC Events Web Socket Bundle provides interface for subscribing to topics and for retrieving events remotely.

Overview

The Web Socket Notifications subscribes to the event topic specified in the URL at the moment that the connection is opened (and unsubscribe when it is closed). Serialization and marshaling of the communication between the Client Web Application and the Server is performed using JSON.

Required Bundles

To be able to receive events via web socket you have to install the following bundles:

• JSON-RPC Event Web Socket Notification Bundle – com.prosyst.mbs.webservices.jsonrpc.event.websocket.jar
• OSGi Event Admin Bundle – com.prosyst.mbs.osgi.eventadmin.jar

For integration with the Policy Admin the following bundles are required:

• JSON-RPC Policy Admin Invoker Bundle – com.prosyst.mbs.webservices.jsonrpc.invoker.policy.jar
• Policy Admin Web Sockets Bundle – com.prosyst.mbs.policyadmin.http.websockets.jar

More information on WebSocket notifications is provided in OSGi Events Application Specification from the WebSockets module.
