You use the
For complete details on the object tag, read the W3 HTML specification.object
tag to deploy applets that are to be used only with Internet Explorer.Following is an example of the
object
tag:<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" width="200" height="200"> <PARAM name="code" value="Applet1.class"> </OBJECT>
The
classid
attribute identifies which version of Java Plug-in to use.The example shown below is the most commonly used form of the
classid
attribute. This example instructs Internet Explorer to use the latest installed version of Java Plug-in.classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"Following is an alternative form of the classid attribute:
classid="clsid:CAFEEFAC-xxxx-yyyy-zzzz-ABCDEFFEDCBA"In this form, "xxxx", "yyyy", and "zzzz" are four-digit numbers that identify the specific version of Java Plug-in to be used.
For example, to use Java Plug-in version 1.6.0, you specify:
classid="clsid:CAFEEFAC-0016-0000-0000-ABCDEFFEDCBA"
You use the optional
codebase
attribute to specify the location to download JRE from in case it is not installed on the system.The codebase attribute has two forms:
codebase=<URL>
With this form, if the JRE specified by the
classid
attribute is not installed locally, then the user is prompted to download the JRE from the URL specified.
codebase=<URL>#Version=major,minor,micro,update
With this form, Java Plug-in compares the
classid
of the locally installed JRE with the required version of JRE, and if the required version is higher, prompts the user to download and install the newer version of the JRE.Following is an example of how to use the
codebase
attribute to set up automatic downloads from the Sun Java Web site:<object classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" width="200" height="200" codebase="http://java.sun.com/update/1.6.0/ jinstall-6-windows-i586.cab#Version=6,0,0,99"> <param name="code" value="Applet1.class"> </object>
Note: In this example thecodebase=http://java.sun.com ...
line is broken for readability. In the actual HTML file it would be one long line.Sun has packaged each version of the JRE installer in Microsoft cabinet (.cab) file format. You can view a list of these releases and the corresponding .cab file names.
