Force Internet Explorer to use a specific Java Runtime Environment install?

Question

When viewing someone else\'s webpage containing an applet, how can I force Internet Explorer 6.0 to use a a particular JRE when I have several installed?

Answer 1

For the server-side solution (which your question was originally ambiguous about), this page at sun lists one way to specify a JRE. Specifically,

The classid attribute identifies which version of Java Plug-in to use.

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 1.5.0, you specify:

classid="clsid:CAFEEFAC-0015-0000-0000-ABCDEFFEDCBA"
