Java and Javascript

[Greg Munt]

Hope you can help me. I'm looking to implement some sort of graphical 
client, within a web browser. I know that this has been done before, 
without requiring the page to be reloaded. They used either Java or 
Javascript, can't remember which.

IIRC, Java is useful on the networking side, whilst Javascript is useful 
when you need firm control of the browser itself. Does anyone care to 
supply advantages/disadvantages of each, and what each should be ideally 
used for?

Should I be looking at both Java *and* Javascript, to complement each 
other, or should I concentrate on using just one of them? How much of the 
Java/Javascript functionality does the potential DHTML/DOM standard 
encompass?
