This application uses the "com.lightstreamer.ls_client" layer of the Lightstreamer Java SE client library to connect to Lightstreamer Server and subscribe to the 30 items. The application code implements auto-reconnection and auto-resubscription logic, together with a connection status indicator.
Java Swing classes are used to display the real-time updates received from Lightstreamer Server. The application code implements a cell highlighting mechanism too.
