I'm studying servlets and JSP's and I was thinking about how they could be applied to a system I'm working with. The current system consists of one process which manages the state of the system, which serves user interface programs running in different processes. The processes communicate using a socket connection, with messages being sent when the state changes.
I've been wondering how I could put a web interface on this system. The problem is I would need an object running in a different thread to process the messages. I could create that object when the ServletContext is initialized and query it from within servlets. Is this a good idea? Is it even allowed? If not, can anyone suggest how I might do this?

It is allowed. However, when multiple requests share the same resource, its methods must be sychronized.
