The Java virtual machine in browsers situation is a real mess. I'll try to
break it down for you as best I can:
Netscape 3.x and IE 3.x: Java 1.0 API only.
Netscape 4.0 -> Netscape 4.05: Java 1.0 API for AWT (GUI), 1.1 for most
other classes.
Netscape >= 4.06 (including 4.5, 4.6): Java 1.1 API on most platforms,
except Macintosh.
Internet Explorer 4.x, 4.5: Java 1.1 API except for RMI classes (this may
have been added at some point)
Netscape 4.x on Macintosh: Java 1.0 for AWT, 1.1 for rest (I think - at
any rate it is not fully 1.1 and may be all 1.0)
Internet Explorer >= 4.x on Macintosh: You can apparently use the MrJ
JVM by specifying it in the
preferences (I've never tried it)
Can you tell I deal with this stuff a lot? :-) One option is to use the
Java plugin from Sun where possible, but that is not anywhere near an
ideal solution. Hopefully the newer browers coming out will allow
selectable JVMs instead of the Netscape way of allowing only theirs or the
makeshift Java plugin.

I don't know, but I'd say it is still a decent percentage - I know a
number of people who think the >= 4.x browsers are too bloated or don't
like the interface. Bottom line is, if you want to reach the greatest
number of browsers with an applet, the Java 1.0 API is still the best way
to do it - however I have seen an increasing number of 1.1 applets used on
web pages, but most of those are specialized and not simple web page
graphics enhancements.

Hope this didn't confuse you too much.
