Supported Features back to top Q: Does Java Plug-in Software offer support for all the features in Java 2 SDK, Standard Edition v 1.3? A: Yes. Java Plug-in Software uses the same JRE that users
can download from Sun's web site today Q: Is Java Plug-in Software fully compliant with the JCK (Java Compatibility Kit) test suite for Java 2 SDK, Standard Edition v 1.3? A: The 1.3 release of Java Plug-in Software is fully compliant with the JCK test suite for Java 2 SDK, Standard Edition v 1.3, including the RMI and JNI tests. Q: Does Java Plug-in Software provide support for Netscape Navigator? A: Yes. Java Plug-in Software supports Netscape Navigator 3.0 and later on Windows 95 and 98, Windows NT 4.0, and version 2.6 and later of the Solaris operating environment. Q: Which Java 2 SDK, Standard Edition v 1.3 software features does Netscape not support? A: There are several, including support for multiple JAR files and not all thread methods are implemented. Netscape has provided further information on known incompatibilities in their JDK 1.1 patch for Communicator at http://developer.netscape.com/. Q: Does Java Plug-in Software support scripting? A: Java Plug-in Software supports scripting of applets in Internet Explorer. However, such scripting is not available when using Java Plug-in Software in Navigator. Because of limitations in Netscape's plug-in API, scripting cannot be supported directly (through LiveConnect) in Navigator. We are working closely with Netscape to address this issue in a future release of Navigator. Q: Does Java Plug-in Software support signed applets? A: Yes, Java Plug-in Software supports standard Java 2 SDK, Standard Edition v 1.3 signed JARs and applets signed using Netscape signing tools. See the Java Plug-in Software documentation for more details. Q: Does Java Plug-in Software support JNI? A: Yes, Java Plug-in Software supports the Java Native Method Interface (JNI). See JNI and Java Plug-in Software for more details. Please note that an applet must be signed to have permission to use JNI. Q: Does Java Plug-in Software automatically recognize and use the proxy server configuration that the browser was using? A: Yes, Java Plug-in Software automatically recognizes the Internet settings in your browser when it starts. It means that it can go over the firewalls/proxies as long as the settings in your browser are correct. Q: Does Java Plug-in Software support proxy-bypass list? A: Yes, the 1.3 release of Java Plug-in Software supports the proxy-bypass list. Q: Does Java Plug-in Software support auto-proxy-configuration in the browser? A: Yes, the 1.3 release of Java Plug-in Software supports
auto-proxy-configuration for both Internet Explorer and Navigator.
Q: What protocol does Java Plug-in Software support over the proxy? A: HTTP, HTTPS, FTP, and Gopher are supported in the 1.3 release of Java Plug-in Software. Q: Does Java Plug-in Software support SSL? A: Java Plug-in Software 1.3 provides HTTPS support but it does not provide direct SSL support. Q: Is there a way to pre-load Java Plug-in Software during the browser startup? A: Internet Explorer and Netscape Navigator do not have mechanisms to support pre-loading Java Plug-in Software during startup. You can work around this limitation by providing your own startup page that launches a dummy applet using Java Plug-in Software. Q: Can I set up Java Plug-in Software to download from an intranet web server (behind a firewall), rather than downloading it from Sun's web site? A: Yes. For more information, see the Guide to Using Java Plug-in Software in Intranet Environments and the Java Plug-in Software documentation page. Q: How can I open the Java Plug-in Control Panel on Microsoft Windows? A: On the Start menu, choose Start-->Settings-->Control Panel, then double click on the Duke icon labeled "Java Plug-in".
Version Information back to top Q: How can I tell what version of Java Plug-in Software has been installed? A: There are a couple of ways:
Q: Can different versions of Java Plug-in Software co-exist on the same system? A: No. Java Plug-in Software for Internet Explorer shares the same unique identifier (CLSID in Internet Explorer, mime-type in Netscape) between different versions. As a result, installing different versions of Java Plug-in Software on the same machine may result in one version being overwritten. We strongly recommend that users uninstall previous versions of Java Plug-in Software before installing Java Plug-in Software 1.3. Notice that installing Java Plug-in Software 1.1.x after installing Java Plug-in Software 1.3 on the same machine is not supported.
