How :Remote system Screen Capture

i would like to know how can we capture the screen of a client ,and display that in our Machine .what are the classes involved ?

Respected Sir/ Mam,
We are doing (Kavitha.E,Nalini.M,Anitha.M) our project in java.Our project title is FAILURE DETECTION AND NETWORK MANAGEMENT SYSTEM .We have a module called Remote Section.In that the server will automatically capture the client system’s screen,detect the failure like mouse connected or not, display found or not like that.We request you to provide guidance for this.

                                         Thanking you
