Puzzler regarding JRE and Applets

Here's one for the authors, as well as others on this forum. How have you solved the problem of needing a certain JRE (say, 1.4.2_08) for your applet to run, yet your users may already have another 1.4.2 runtime on their machine (say 1.4.2_06). Assume that the users aren't technically savvy. I know that you can specify this using CLSID when declaring your applet in either a JSP or HTML file, but I'm looking for some good advice on how this problem was solved in real world situations.

Well, you've certainly stumped me with that one: I am not an expert on deployment. Perhaps my brother will have better luck with it.

I've heard that Java Web Start can do this for you, but I don't know the details.
I agree. Here's the link:
