General Deployment Enhancements in J2SE 5.0 (original) (raw)

• Much of the common functionality between Java Plug-in and Java Web Start has been combined. There is now a single Java Control Panel for both. It replaces both the Java Plug-in Control Panel and the Preference panel of the Java Web Start Application Manager. The settings are used in both products. (4667682)
• Security: (1) This release features improved security access and control, including both user- and system-level security options and an expanded list of deployment properties. (4667645) (2) Several new configuration properties have been added so that an enterprise can customize user security settings. These allow control of what applications a user is allowed to grant trust to, and what permissions are given to code for which trust is granted. Also, a user or enterprise can configure what information is to be displayed on security warnings; and an enterprise can configure if a user is allowed to run applications in the enhanced sandbox of the JNLP API. An enterprise can also pre-accept its own certificates so that users will not see any security warnings in its own applications.
• Enterprise Configuration: Both deployment products can now be configured with an enterprise configuration file. This file, accessed as a URL, can set any set of configuration properties, either as defaults, or as locked properties which cannot be overridden by the user.
• Support is available for pack/crunch compression for downloading Java applications and applets. Pack200, a new hyper-compression format for JAR files defined by JSR-200, can reduce the download size of JNLP applications and Java Plug-in applets. File size can be reduced to about 1/8th of the original size. (4666040)
• Support of browser keystores in Internet Explorer and Mozilla in Java Plug-in and Web Start: Certificates and keys in browser keystores will be used for signing verification, HTTPS server authentication, and HTTPS client authentication. Certificates and keys on the smart card exposed in the browser keystore will also be recognized. See Browser Keystores for more information. (4480333, 4957907)
• Support of time-stamped, signed JAR files: With time-stamping now built into the signing tool, Java Plug-in and Java Web Start now recognize the time-of-signing information when they verify a signed JAR file. This solves the problem of a signed applet signed with a valid certificate at time-of-signing but the certificate expired later after the applet deployment. (4649690)
• Support of Client Authentication in HTTPS: This release provides interactive user interface in Java Plug-in and Java Web Start during HTTPS client authentication for users to select the personal certificate from the personal keystore. (4802844)
