Is there any way I can set the jre version before I open the browser

I want to set the jre version of the browser before I open the window. Can I have any batch script that does this? Is this possible does any body already did this?

Have you tried the applet tag to specify the version runtime yourapp will use? Here's a link to an old documentation, but theprinciple should still apply, if it's what you're looking
