The X Window System for displaying graphical user interfaces on UNIX and Linux systems has just been re-architected to support enterprise-class distributed applications across LANs, WANs, and the Internet. This is the first and only authoritative guide to the new X Window System, codenamed Broadway, and officially titled X11R6.3. Discover how Broadway can allow any user to access any application from anywhere on the Internet, while significantly improving the performance of existing enterprise applications. Learn how Broadway has evolved from its X roots; review its components, security features, and Internet-focused architecture; and understand the tasks required to enable enterprise applications to execute remotely across the Internet. Finally, compare Broadway with JavaaA A based solutions, and understand how Broadway and Java can work together. The book contains more than 50 figures and illustrations demonstrating Broadway enterprise solutions -- with corresponding sample code available on the Web. For all IT managers, architects, designers, developers, and administrators of large-scale distributed applications and environments.
