This chapter includes the following information:
Although Sun Microsystems continues to release new versions of Java through its Java Development Kit (JDKTM), the Java Runtime Environment (JRE) included with Netscape Navigator remains at version 1.1.5. Java Plug-in for Solaris bridges this gap by utilizing Navigator's plug-in architecture to distribute the latest JRE to Navigator users. Java Plug-in 1.2 provides support for JRE 1.2.1_03 with Netscape Navigator 4.05 or compatible. For more information on system requirements, see "Requirements".
To invoke Java Plug-in, you include the HTML <EMBED> tag in your Web pages. When Navigator encounters the <EMBED> tag, it loads Java Plug-in and runs Java applets, JavaBeans, and other components using all the features of the "external" JRE included with Java Plug-in.
For more information on updating your Web pages to work with Java Plug-in, refer to the HTML Specification. In addition, you can download the Java Plug-in 1.2 HTML Converter free of charge, which automatically makes the necessary changes.
Tailored specifically for Netscape Navigator running on SolarisTMplatforms. Other Java Plug-ins, available from Sun's Java Software group, are developed for use with Internet Explorer and Netscape Navigator running on Microsoft Windows platforms.
Sun does not support the use of any JRE prior to 1.2.1_03 with Java Plug-in 1.2.
Installs at the system level by default, so you can install the plug-in on a centrally-located server and all users can access the plug-in over NFS.
Can coexist on the same machine with Java Plug-in 1.1.2 (in different locations). With other versions, you can only install one Java Plug-in on your machine.
Uses native threads. Java Plug-ins available from Java Software use green threads. See the Java White Paper for more information on Java multi-threading.
Full JDK 1.2 support -- Enables you to develop and deploy applets, taking full advantage of JDK 1.2 features and functionality such as the security model, Remote Method Invocation (RMI), JavaBeans, signed applets, and the Java Native Interface (JNI).
Updated HTML -- You must modify your Web pages with the <EMBED> tag to invoke Java Plug-in 1.2, even if you modified these pages to work with a previous version of Java Plug-in. You must modify the original, unconverted HTML. Refer to the HTML Specification for more information on updating your Web pages with the <EMBED> tag. In addition, you can download the Java Plug-in 1.2 HTML Converter free of charge, which automatically makes the necessary changes.
Network -- A direct LAN (Ethernet) connection with high-speed Internet connection, or dial-up modem running 28.8 baud or faster.
