9 Students prefer Single sign-on even if that means revealing personal logons and passwords [aggregation/credential caching] Selection of content [channels] and layout [user profile] Common channel navigation and icons [consistent look & feel]

10 JA-SIG Java In Administration Special Interest Group Conferences biannually Clearing house Collaborative projects

11 Mission 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.

12 Goals The JA-SIG's goals are to: Nurture communication of best practices, new technologies, and innovative methodologies and projects related to Java Increase peer review, collaboration, and group discussion related to institutiondeveloped Java administrative applications Broaden Java technology cross-fertilization between firms and schools on both a functional and geographic basis

13 Activities The JA-SIG membership is engaged in three activities. 1. Sponsorship of a twice-annual conference. 2. The JA-SIG Clearinghouse - a place on the Web to facilitate the sharing of Java components. 3. Development of a free, open source, open standard portal for higher education: uportal.
