A system network-based instrument is trend in order to include an active function in a currently industrial field. However, there are many different kinds of the computing environments that industrial instruments are applying, and the system that possessed a networking function is very expensive. A Java to execute in an independent computing environment has enough advantages to establish environment requested in an industrial field. In this paper, we propose the active measurement diagnosis system that can compose a Java-based industrial embedded computing environment. A Java platform of a proposed system is including a module and Java API used in an industrial field. This system can easily integrate different execution environment between each target systems. In this way, an active measurement diagnosis system simplifies system structure and equally makes a computing environment between systems.
