IGMission
The Java in Administration Special Interest Group (JA-SIG) is an independent organization designed to increase the flow of information between educational institutions and companies involved in the development of administrative applications using Java technology.
Today, with the benefit of object oriented technology and Java, we have a great opportunity in higher education to do things better as colleagues. The purpose of JA-SIG is, first, to share our experiences as we build applications with Java, and second, to develop a common infrastructure upon which we can build shareable components. We welcome the participation of both educational institutions and commercial enterprises in this effort.
