Client/Server/Servlets Design Problem

Hello,

since 1 month i work on a server, which check all 5 seconds for change on some sensors. the server could register multiple modules (in form of objects) for multiple sensors, so if one state of a sensor change, the registered's moduls for this specific sensor will be invoke and compute something. this system i call my backend.

now i want control this backend with a web-frontend, to monitor the states of sensors, watch the modul results.... my problem, which communication between servets/jsp of frontend and my backend should i use?
