Hi Karl. It depends on the sites you are visiting. For example I listen to 
Internet radio from http://www.bbc.co.uk/radio4. To listen to programs from 
this site I need to have the realplayer plugin installed, although for some 
of their other stations, windows media player is an option, and for this I 
have to install mplayerplug-in, which also pulls in mplayer, and other deps.

Other sites use flash for some stuff, and if you dont have the flash-plugin 
installed, you are not going to see the stuff that needs flash. Of course 
this may be no problem, as the flash stuff may be just ad's, but if it's a 
flash video that you want to view, the flash-plugin is a necessary 
requirement.

It's no different with java. Some sites are setup using java, and to be able 
to load and view the java applets, you need to have the JRE installed.

What this comes down to is this. Depending on which sites you need to use, you 
may find that some of them need java to be installed, otherwise the site 
won't work, and will be of no use to you. Look at this one as an example.

http://www.itautrade.com.br

The Monitor window on the right of the webpage loads, and runs the applet, and 
displays a graph, and also a ticker at the bottom of the window.

I could do with some more sites that specifically require java. They will will 
be usefull as test sites to checkout your JRE, and if it's performing as 
intended.

Bloody digests. Nobody has the faintest idea what a reply referencing "Digest, 
Vol 45, Issue 259" is referring to, and I'm replying to this nondescript 
subject line.

I think it's about time that the option to receive posts to the the list as a 
digest should be removed. It's anybodies guess what the archives look like, 
with subject lines referencing a digest, and no subject defined.

A couple  of days late, but for what it's worth, and if anybody reads this 
reply to a digest subject line, I'm posting my reply anyway.

Nigel.
