Internet and Java technology have developed enormously in recent years. These dramatic developments
have provided opportunities and challenges in all fields, particularly in the field of education. What we could not imagine doing just a couple years back has been made possible by these technologies. This short paper illustrates one such example. The example we will discuss is an examination system that a student takes online. When done, the system displays his/her score, and stores the name of the student and his/her score in a file on the server. By clicking another button the students can see answers to all the questions. The way we have done, all the processing is done on the client side and then the result and the name are sent to the server. The server stores the name and score of the student in a file on the server. A Java applet does the client side computation and a Java Servlet does the processing on the server side. The paper illustrates the power of applet servlet communication.
