Utilization of Java-based web application for educational visualization

Abstract

People in ICT domain must prepare some environmental changes based on Operating systems and Programming languages. Instructors and learners of higher education, for example, sometimes face unfortunately drastic changes where their educational tools can not work correctly nor suitably although they were exactly working at the previous environments. This paper describes one of such an environmental change and how to recover performance of relevant tools from "before" to "after". One of keywords is Java programming language. And we have designed and implemented our tool with Java programming language not only as Applet but also as Stand-alone application. When we face an environmental change, we have struggled to adjust our tool for newly changed situation with possibly efficient modification. Although our results are not so good for several requests, they can bring us some kind of satisfaction to utilize our tools on the newly changed environment and provide tolerable effects on education using such tools in university lectures. Our employed approach did not assume environmental change, but its flexibility has been not only lucky but also suitable enough to override such a change and to keep its performance.
