Where'd appletviewer come from?

[Kent West <westk@acu.edu>]

On my Sid box, I have the program /usr/bin/appletviewer that is a Java 
run-time thing that allows me to run web-based Java apps outside of a 
web browser. I can't tell if it's something that I installed with 
Blackdown's java, or Sun's java, or some Debian package, or what 
("apt-cache search appletviewer" comes up empty).

Now I need to upgrade to Java 1.4 (from 1.3) to access so me features in 
our corporate database system. I've tried downloading both Blackdown's 
and Sun's 1.4 JRE, but neither appears to have provided me with a new 
appletviewer.

Anyone know how I can get this appletviewer to be Java 1.4 instead of 1.3?

Thanks!

Kent
