Fact or fiction: If I write an applet for somebody else's web page, the applet needs to be re-compiled & the html conversion re-done as often as a new java version comes out?
If the truth IS this bitter, how often have these updates occurred in recent years?

If that were the case then no one would be writing Java applets any more!
Historically, Microsoft has included an old VM with their IE product, and since they have a monopoly on web browsers, most computer systems come with that old java VM. So, if you write java applets that work for that version of java, you won't have to do anything special.
If you want to use newer features of the java language that the old MS VM doesn't support, you'll have to install the Sun plug-in and update your VM version. The user experience is much better with the modern VM, but if you limit your code to the APIs that run in the old VM, you won't have to recompile anything.

And the old VM is java 1.1.7 ?
But still, if I write a swing applet and compile it with java 1.3.1, will the new plug-in (1.4.?)
fail to run it?
I can't install/reinstall on this school's machine so I can't just try & see...

No it will not fail to run it. It will run it just fine.
