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?
If you mean when you are not the person writing the web page, then you could disable the add ons you do not wish to use with the Manage Add-Ons IE Options screen added in Win XP SP2
You can specify the family of JRE to be used. http://www.oracle.com/technetwork/java/javase/family-clsid-140615.html
