MOUNTAIN VIEW, Calif. (December 4, 1995) -- Netscape Communications Corporation (NASDAQ: NSCP) and Sun Microsystems, Inc. (NASDAQ:SUNW), today announced JavaScript, an open, cross-platform object scripting language for the creation and customization of applications on enterprise networks and the Internet.  The JavaScript language complements Java, Sun's industry-leading object-oriented, cross-platform programming language.  The initial version of JavaScript is available now as part of the beta version of Netscape Navigator 2.0, which is currently available for downloading from Netscape's web site. 

In addition, 28 industry-leading companies, including America Online, Inc., Apple Computer, Inc., Architext Software, Attachmate Corporation, AT&T;, Borland International, Brio Technology, Inc., Computer Associates, Inc., Digital Equipment Corporation, Hewlett-Packard Company, Iconovex Corporation, Illustra Information Technologies, Inc., Informix Software, Inc., Intuit, Inc., Macromedia, Metrowerks, Inc., Novell, Inc., Oracle Corporation, Paper Software, Inc., Precept Software, Inc., RAD Technologies, Inc., The Santa Cruz Operation, Inc., Silicon Graphics, Inc., Spider Technologies, Sybase, Inc., Toshiba Corporation, Verity, Inc., and Vermeer Technologies, Inc., have endorsed JavaScript as an open standard object scripting language and intend to provide it in future products.  The draft specification of JavaScript, as well as the final draft specification of Java, is planned for publishing and submission to appropriate standards bodies for industry review and comment this month. 

JavaScript is an easy-to-use object scripting language designed for creating live online applications that link together objects and resources on both clients and servers.  While Java is used by programmers to create new objects and applets, JavaScript is designed for use by HTML page authors and enterprise application developers to dynamically script the behavior of objects running on either the client or the server.  JavaScript is analogous to Visual Basic in that it can be used by people with little or no programming experience to quickly construct complex applications.  JavaScript's design represents the next generation of software designed specifically for the Internet and is:

designed for creating network-centric applications

complementary to and integrated with Java

complementary to and integrated with HTML

open and cross-platform. 

With JavaScript, an HTML page might contain an intelligent form that performs loan payment or currency exchange calculations right on the client in response to user input.  A multimedia weather forecast applet written in Java can be scripted by JavaScript to display appropriate images and sounds based on the current weather readings in a region.  A server-side JavaScript script might pull data out of a relational database and format it in HTML on the fly.  A page might contain JavaScript scripts that run on both the client and the server.  On the server, the scripts might dynamically compose and format HTML content based on user preferences stored in a relational database, and on the client, the scripts would glue together an assortment of Java applets and HTML form elements into a live interactive user interface for specifying a net-wide search for information. 

Java programs and JavaScript scripts are designed to run on both clients and servers, with JavaScript scripts used to modify the properties and behavior of Java objects, so the range of live online applications that dynamically present information to and interact with users over enterprise networks or the Internet is virtually unlimited.  Netscape will support Java and JavaScript in client and server products as well as programming tools and applications to make this vision a reality. 

"Programmers have been overwhelmingly enthusiastic about Java because it was designed from the ground up for the Internet.  JavaScript is a natural fit, since it's also designed for the Internet and Unicode-based worldwide use," said Bill Joy, co-founder and vice president of research at Sun. " JavaScript will be the most effective method to connect HTML-based content to Java applets." 

Netscape's authoring and application development tools -- Netscape Navigator Gold 2.0, Netscape LiveWire and Netscape LiveWire Pro -- are designed for rapid development and deployment of JavaScript applications.  Netscape Navigator Gold 2.0 enables developers to create and edit JavaScript scripts, while Netscape LiveWire enables JavaScript programs to be installed, run and managed on Netscape servers, both within the enterprise and across the Internet.  Netscape LiveWire Pro adds support for JavaScript connectivity to high-performance relational databases from Illustra, Informix, Microsoft, Oracle and Sybase.  Java and JavaScript support are being built into all Netscape products to provide a unified, front-to-back, client/server/tool environment for building and deploying live online applications. 

Java is available to developers free of charge.  The Java Compiler and Java Developer's Kit as well as the HotJava browser and related documentation are available from Sun's web site at http://java.sun.com.  In addition, the Java source code can be licensed for a fee.  Details on licensing are also available via the java.sun.com web page.  To date, Sun has licensed Java to a number of leading technology companies, including Borland, Macromedia, Mitsubishi, Netscape, Oracle, Silicon Graphics, Spyglass, and Toshiba.  Sun's Workshop for Java toolkit is scheduled for release in Spring 1996.  Sun's NEO product family, the first complete development, operating and management environment for object-oriented networked applications, will also use Java-enabled browsers as front-ends to the NEO environment. 

Netscape and Sun plan to propose JavaScript to the W3 Consortium (W3C) and the Internet Engineering Task Force (IETF) as an open Internet scripting language standard.  JavaScript will be an open, freely licensed proposed standard available to the entire Internet community.  Existing Sun Java licensees will receive a license to JavaScript.  In addition, Sun and Netscape intend to make a source code reference implementation of JavaScript available for royalty-free licensing, further encouraging its adoption as a standard in a wide variety of products.
