    Cool JVM vs JRE vs Java Plug-In and Yahoo Chat!

    Hi

    I am a little confused as to what is required in the browser to run an applet.

    Do I require JVM installed in my browser?
    Do I require Java Plug-In installed in my browser?
    Do I require JRE installed in my browser?

    What is the difference between these three?

    My second question is about the version of JDK to use while developing Java Applets. I am planning to make a Chat Application similar to Yahoo chat. For that I made a beta version using JDK 1.4.2 but now the problem is that most of the client browsers have old version installed for e.g. 1.1.4 by Microsoft or 1.2 by Sun.
    In this case almost every user that uses my chat applet has to download the latest version from http://java.sun.com/getjava otherwise it the chat applet doesn't work on their browser. And I don't want this to happen because most of the time it takes ages to download and install the latest Java version on client browser. Yesterday on Pentimum 4 having 512 MB RAM and Windows 98 with 56K modem and it took almost 45 minutes to download and install which is unacceptable.
    If you see the Yahoo chat http://chat.yahoo.com you will see that it is developed in such a way that it supports almost all the browserd without having to install the latest version. This is what I want to achieve and I am looking from your input as to how do I make sure that the client doesn't need to install the latest version (or atleast very few clients need to install latest version). Do I need to make this chat application in an old JDK version for e.g. 1.1.6?
