Architecture of computer supported collaborative learning based on EJB middleware and it´s implementation [it´s read its]

This work presents a EJB-based computer supported collaborative learning (E-CSCL) system model. It can support the collaborative work which is discontinuing in time and distributive in space, and has mutual dependence in the learning process, which provides a face to face and WYSIWIS (What you see is what I see) collaborative learning environment. This model uses the multitier architecture. Finally, the chat tool and the whiteboard tool based on EJB middleware are given as examples.
