Hi
I would like to have your opinion guys especially of Jose.
I am trying to develop a chatting applet that will allow users to do voice and video chat.
I want to make sure that all all the browsers support my chat application without having to install the latest JVM. Most old browsers on Windows have MS JVM 1.1.4.
The problem with installing latest JVM which is 1.4 is that it is 15 MB in size and takes ages to download on a dialup connection.
For this reason I am sticking to AWT instead of Swing for GUI. If I use Swing then it won't work on browsers having MS JVM 1.1.4 which I don't want.
So far so good but now I am facing problems incorporating audio and video features as I will have to use Java Media which will require all the client browsers to update their JVM isn't it!?
Is there a way through which I make sure that the audio & video works on the older versions of JVM?
If you take a look at this chatting software called GlassRoom http://www.chatessentials.com you will find that it works on IE 5 with MS JVM 1.1.4. It has audio chat feature.
Please give me your opinions and suggestions.

hmmm... yes you are write that in the future new version of IE will have new version of JVM rather than the old MS JVM 1.1.4 but whatever the version is it will support the old version due to backward compatibility.
its like those having JVM 1.4 or later can run the applet compiled in Java 1.3 but those having MS JVM 1.1.4 (most of the old browser have MS JVM by default) will not be able to run it.
so to be on the safe side i will stick to the old version. after doing some work i found out that if you compile your code in Java 1.2 then those having MS JVM 1.1.4 will be able to run it. but your code should contain AWT components rather than SWING otherwise it won't work.

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?
