Note: This page describes what is new in the 1.3.0 release of Java Plug-in. For what is new in the 1.3.0_01 and higher-version releases of Java Plug-in, see:
The 1.3 release of Java Plug-in software supports two new features focusing on effective applet deployment and enabling considerably faster applet performance through the new Java Hotspot Client VM.
Java Plug-in 1.3 software is part of the Java 2 Runtime Environment (JRE) 1.3 for Windows which is included with the Java 2 SDK for Windows. If you download either the Java 2 SDK 1.3 or JRE 1.3 for Windows, you will also receive the latest version of the plug-in.
Java Plug-in software is not available as a separate download. In order to redistribute Java applets using the plug-in, you must download JRE 1.3 which includes the appropriate no-fee redistribution license.
For Solaris users, Sun is offering a tuned version of Netscape Communicator and the plug-in.
Prior to version 1.3, applets were cached in the same cache used by the browser for all web documents. Unfortunately, this meant that a cached applet could be flushed out later by the browser to make room for new documents. This is problematic for frequently used applets where it is key to eliminate all unnecessary downloads. With this new feature, the applet deployer can ensure that the appet will stay on the disk in an area that the browser cannot overwrite. The applet will be downloaded again only if it is updated on the server.
See Applet Caching for more information.
When used effectively with code shared between multiple applets, this can lead to more efficient memory utilization, faster startup and ease code reuse.
See Extension Versioning for more information.
Note the Control Panel is now found in a more intuitive location, under the Windows Control Panel, instead of under the "Programs" section on the Start menu.
For more information about these features, see the related documentation.
For information about the new features in the Java 2 SDK, Standard Edition v 1.3, see the Java 2 SDK README.
