Leveraging Java applets: toward collaboration transparency in Java

Abstract

Widespread use of the Internet is giving rise to the need for collaborative applications that link users at remote sites. Many toolkits support the development of collaboration-aware applications, those developed specifically for cooperative work by multiple users. Another approach is collaboration transparency, the collaborative use of applications originally developed for a single user. When the runtime environment supports collaboration transparency, an application programmer need not write new code to make an application collaborative. Thus, collaboration transparency leverages the existing base of single user applications by extending them to collaborative use. We review options for providing collaboration transparency. We also discuss how collaboration transparency can be incorporated into Sun Microsystems' Java, the most widely used vehicle for developing interactive World Wide Web applications
