The Fastpath plugin adds support for managed queued chat requests, such as a support team might use. For example, a web based "Live Support" interface can point a potential customer at a workgroup representing the Sales team. Members of that workgroup will receive notification that a someone is waiting and when someone from that workgroup accepts, the customer and the team member will be connected to communicate with each other.
Copy fastpath.jar into the plugins directory of your Openfire installation. The plugin will then be automatically deployed. To upgrade to a new version, copy the new fastpath.jar file over the existing file.
