I would create your shared state bean, and add it as a Server
attribute - this can be done via a Jetty XML file and module like you
have already done.
This bean would then be easily retrievable from the ConnectionFactory
implementation, and passed to Connections.
You can then have a custom context XML file for your webapp, that
retrieves the bean from the server and sets it as a context attribute.
This file can be something like (pseudo code to convert to XML):
Server server = this.getServer();
Object bean = server.getAttribute("mySharedBean");
this.setAttribute("mySharedBean", bean);
where "this" is a WebAppContext (as per Jetty context XML file).
