Ensuring JVM version #

[Alan Armstrong]

I'm writing a commercial product that uses applets. Here's my concern:

I don't want to test my applet against every single version of the
JVM.

I understand that I could specify a specific JVM version, but that
will "clobber" the global VM version, which doesn't seem too polite.

Anyone know a way around this? Or am I missing something?

Unless you are doing a small range of esoteric
things, the version of Java you need is 'enough'.

You might be using FocusManager or InputMap and
require Java version 1.4+ for example.

In that case, you can use the JavaVersionApplet to
redirect users with pre 1.4 VM's to another page, vis.
