- Introduction
-
- The Java Plug-in (formally known as Project Java Activator) is a
- new product from Sun Microsystems' JavaSoft division. It allows
- web page authors to direct Java applets or JavaBeansTM components
- on their intranet web pages to run using Sun's Java Runtime
- Environment (JRE), instead of the browsers default Java runtime.
- This release provides support for Microsoft Internet Explorer
- 3.02 or later on Win32 platforms (Windows 95 and Windows NT 4.0),
- and Netscape Navigator 3.0 or later on Win32 and Solaris
- platforms (Solaris 2.5 and 2.6). The Java Plug-in delivers full
- Java Development Kit (JDKTM) 1.1 support and Java Compatibility
- Kit (JCK) compliance to Internet Explorer and Navigator users.
-
- The Java Plug-in is designed for enterprise customers who wish to
- deploy JDK 1.1-based applets on their intranet web pages today.
- This product ensures that enterprises realize the "write once,
- run anywhere" benefits of the Java platform on Win32 and Solaris
- systems on the most widely used web browsers. More specifically,
- web pages modified to support the Java Plug-in allow users to JDK
- 1.1-based applets in Internet Explorer or Navigator, taking full
- advantage of all of the features and capabilities of JDK 1.1
- (such as JavaBeansTM, RMI, JNI, and so on), and have confidence
- that they will run reliably and consistenly.
-
- The Java Plug-in is ready for JDK 1.2 and the high-performance
- Java HotSpotTM virtual machine with a future-ready architecture.
- Thus, when Sun adds new features or functionality to the Java
- Development Kit, Win32 and Solaris users can take full advantage
- of them in Internet Explorer and Navigator immediately by
- deploying the latest release of the Java Plug-in. Sun will
- provide an updated releases of the Java Plug-in that delivers the
- support for the full feature set of JDK 1.2 and the Java HotSpot
- virtual machine later this year. This will make the process of
- upgrading all users in an enterprise to the latest JDK feature
- set as easy as modifying one web page on your intranet.
-
-
-
- Java Plug-in Features
-
- The Java Plug-in delivers several key capabilities to enterprises
- using Internet Explorer and Navigator:
-
- * Full JDK 1.1 support: Allows enterprise developers to
- develop and deploy applets, taking full advantage of JDK 1.1
- features and functionality, such as RMI, JavaBeans, and so
- on.
- * Full Java CompatibleTM support: The Java Plug-in utilizes
- the latest release of Sun's JRE, which is fully compliant
- with the Java Compatibility Kit (JCK) test suite.
- * Future-ready JDK Architecture: Java Plug-in features an
- architecture that makes it easy for Sun to bring new JDK
- features and functionality, including those contained in JDK
- 1.2 and the high performance Java HotSpot virtual machine,
- to Windows and Solaris desktops much more quickly than has
- been previously possible.
- * Free public download and easy install: Upon encountering a
- web page that specifies Java Plug-in, the browser will
- download and install all the necessary files and render the
- applet, requiring minimal user intervention.
- * Free Java Plug-in HTML Converter: Makes it easy and
- automatic for IS managers and web page authors to modify
- their HTML pages to specify the use of Java Plug-in rather
- than the browser's default Java runtime.
-
-
-
- Installing and Running the Java Plug-in
-
- The first time the web browser encounters a web page that
- specifies the use of the Java Plug-in, the browser must download
- and install the required files. Download and install times will
- vary depending on the type of network connection and overall
- system performance. Typical total download and installation
- times (over a local area network) will vary from three to ten
- minutes. In subsequent encounters of web pages that specify the
- use of the Java Plug-in, it is invoked instantaneously from the
- user's hard drive and the applet is rendered.
-
- Internet Explorer: When Internet Explorer first encounters a web
- page that has been modified to specifies the Java Plug-in,
- Internet Explorer will ask the user if it is OK to download an
- ActiveX control signed with a VeriSign digital signature signed
- by Sun Microsystems, Inc. If the user says "Yes", Internet
- Explorer will quickly download a small ActiveX control from Sun's
- web site that will handle downloading the main Java Plug-in
- ActiveX control and Sun's JRE. This will include selecting the
- appropriate locale-specific JRE and offering the user a list of
- suitable download sites. It will then download the files
- automatically and install them. The Java Plug-in ActiveX control
- will then run and use its parameters in the <OBJECT> tag to
- render the applet. The next time Internet Explorer encounters a
- web page modified to support Java Plug-in, Internet Explorer will
- seamlessly load and run the ActiveX control and JRE from the
- local disk, requiring no user intervention.
-
- Netscape Navigator: When Navigator first encounters a web page
- that specifies the Java Plug-in, users will see a plugin-missing
- picture on the HTML page. When the user clicks on this picture,
- Navigator will direct the user to the Java Plug-in download page.
- Users can then download the version of Java Plug-in for their
- operating system and install it. Once it is installed, the Java
- Plug-in will then run and use its parameters in the <EMBED> tag
- to render the applet. The next time Navigator encounters a web
- page that specifies the Java Plug-in, Navigator will seamlessly
- load and run the plug-in and JRE from the local disk, requiring
- no user intervention.
-
-
-
- How the Java Plug-in Works
-
- The Java Plug-in does not replace or modify the browser's
- underlying Java runtime. Rather, it simply allows web page
- authors to specify the use of Sun's JRE instead of the default
- Java runtime for a given web page. This ensures enterprise
- developers that JDK 1.1-based applets are executed with full
- support for all of the features and capabilities of JDK 1.1
- (including the JavaBeans component model, RMI, JNI, and so on)
- in Internet Explorer and Navigator.
-
- The Java Plug-in leverages Internet Explorer's extension
- mechanisms in order to allow Sun's JRE to run inside Internet
- Explorer. The technology used to achieve this is Microsoft's
- COM/ActiveX. Using the HTML <OBJECT> tag, web page authors can
- run ActiveX controls or COM components as part of a web page.
- Internet Explorer provides elaborate mechanisms for downloading
- and caching ActiveX controls. This make it possible for the web
- browser to use Sun's JRE with minimal user intervention.
-
- The Java Plug-in leverages Navigator's plug-in architecture in
- order to allow Sun's JRE to run inside Navigator, much like users
- can run QuickTime movies or Shockwave animations with plug-ins
- today. Using the HTML <EMBED> tag, web page authors can cause
- plug-ins to be run as part of a web page. This make it possible
- for the web browser to use Sun's JRE in Navigator.
-
- In order to utilize all of the features and capabilities of JDK
- 1.1 in Internet Explorer or Navigator, web page authors must
- specify the use of Sun's JRE via the Java Plug-in. Thus, web
- pages must be modified in order to invoke Sun's JRE. Sun
- provides a written specification to guide web page authors on how
- to make these changes. In addition, Sun provides the Java Plug-in
- HTML Converter, free of charge, that will automatically make the
- changes to the selected set of HTML pages.
-
- Java Plug-in uses the same JRE for Win32 and Solaris that users
- can download from Sun's web site today.
-
- All JDK 1.1-based, 100% Pure Java applets should run unmodified
- using Java Plug-in.
