codebase 를 통해 JRE를 자동 설치하게 하는 기능은 activex 를 이용한 방식이기 때문에 IE에서만 가능하다



For static versioning, set codebase equal to:

http://java.sun.com/products/plugin/autodl/<.cab file for the version you want>

For example, for static versioning for the 1.4.2 release (which uses classid of clsid:CAFEEFAC-0014-0002-0000-ABCDEFFEDCBA), set codebase to:

http://java.sun.com/products/plugin/autodl/jinstall-1_4_2-win.cab

For a complete list of JRE releases that can be autodownloaded via .cab files, see Autodownload Files (Windows Only).

For dynamic versioning (which uses classid of clsid:8AD9C840-044E-11D1-B3E9-00805F499D93), set codebase equal to:

http://java.sun.com/products/plugin/autodl/jinstall-<major version of family in underscore format>-windows-i586.cab#Version=<full version number for lowest version in family in comma-separated format>

If no version of Java is installed, or a version less than the major version of the family is installed, then this will cause automatic redirection to the latest .cab for the latest version in the family.

For example, for the 1.4.2 release you would set codebase as follows:

http://java.sun.com/products/plugin/autodl/jinstall-1_4-windows-i586.cab#Version=1,4,0,0

If the user had version 1.3.1 installed, then the latest version in the 1.4 family would be downloaded and installed. But if any version in the 1.4 family were installed, then it would be used and no download would take place.

Note that the autodownload .cab files can change as patch releases are released. See below for more about the interpretation of codebase.


Attribute codebase

It should be a full URL pointing to a .cab file somewhere on the network. It's purpose is to allow downloading and installation of Plug-in if either no version of Plug-in is installed on a user's computer or if no appropriate version of Plug-in is installed. The URL should, by default, point to a page on the website.

Examples:

In the above example, codebase is:

codebase="http://java.sun.com/products/plugin/autodl/jinstall-1_4_2-windows-i586.cab#Version=1,4,2,0"

Note that this was for static versioning and that the version number appended to the .cab file indicates that 1.4.2 version of Plug-in needs to be installed on the user's computer, otherwise an attempt will be made to download and install it.

For dynamic versioning, codebase would be as follows:

codebase="http://java.sun.com/products/plugin/autodl/jinstall-1_4-windows-i586.cab#Version=1,4,0,0"

The appended version number indicates that if the user has version 1.4.0 or higher of the Plug-in installed on the computer, no download will occur. In other words, if the installed Plug-in is in the 1.4 family (major version 1.4), then it will run. If the installed version is lower, however, then an attempt will be made to download and install a newer version via the .cab file.

PARAM elementcodebaseSpecifies the base URL of the applet. The URL can be relative or absolute but it should be in the domain of the current document. This PARAM element is required only if the applet is not located in the same directory as the document.
