<body>
<script language="Javascript" type="text/javascript">
       if(!navigator.javaEnabled()){
             alert('Enable your java to expeirience this java enhanced page  or\n try install it...');
             location.replace('http://java.sun.com');
             window.open('instructionsforintallingjava.html');
        }
        else{
              document.write('<applet watever></applet>');
         }
</script>
<noscript>
Enabled javascript please
</noscript>
</body>

The problem is this work fine in my browser firefox and internet explorer8 but in old internet explorer browser and a new browser named fix browser and some version of firefox also this won't work, can any one tell me why this is happening and how can i overcome this.
Also in the

location.replace('installing java.html');

i have an applet in case when applet doesn't appear this installing page instruction appear in place of applet. I show a link in the replace location.
The problem is when i clink on this link it open page in the small portion reserve for applet. I want when people click on this link it open in the new page. Please tell me how i do this also.

Hi terry,

<?php 

$id = $_GET['Uniqueid'];
$uname = $_GET['Username'];

Hi essential :icon_smile: ,
Hope you will be fine. First of all thank you very much for your help. I try your script but there is a problem i don't no why this is happening actually if i try your code its show an alert if i have java installed , its not work on internet explorer 6 i think its a different issue its not script specific, yes your script solve the problem of different versions of firefox, but please check your script why it shows an alert if java is installed, i try different things but i am not succeeded. In IE6 it shows a message object doesnot support this property or method, i search the error and i found IE cause problem for some reasons i check it out , on IE 7 i try it with out java installed its work perfectly fine , on my system i have IE 8 and java too and it shows an alert that you use in your script . So please check it why this is happening.
One thing more if i place this file in a server and then run it by giving url of the file such as http//www.abc.com/voicemail/CapturePlayback1.php it works on IE 6 but when i run the file through the email client where i place the recorder nothing shows on IE 6 but with a error that i already told you above.
Again thanks for your help and time :icon_smile: .
Thank you.

Hi Essential,
Hope you will be fine, Sorry for late reply actually i was solving another problem and the problem is the recorder for which you write scripts for me :P is not attaching the files , i solved it, the problem is the uniqueid parameter $id = $_GET; is not generated, i don't no why it was happened but somehow i manage to solve it.
I tried your script but it's give me XML parsing error, This time i m attaching a file so you get better understanding how my recorder is display in the page, the place where error is shown, looks blank when the recorder is not shown.
Another problem is that you'll see its a small box so when something goes wrong the people unable to read the whole thing as it is happened in this case also, you couldn't see the whole error because it is going outside the window, the same thing happen if you use location.replace, its open the page in the small square and people unable to read any thing.Actually its a blank page whose called in an iframe and the code is

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

      alert('Enable your java to expeirience this java enhanced page or\n try install it...');
      window.open( "http://www.java.com/en/download/index.jsp", "JAVA Installation Manual", "width=500, height=500, location=0, scrollbars=1, toolbar=0" ); 
   }
</script>
<noscript>
Enabled javascript please
</noscript>
<div id="body">
</div>
</body>
</html>

If you remove the JavaScript then this is the page that is shown when recorder is not shown. I add script here to see whether its work or not and if change the condition then read below what happened.
Another thing that may be helps you is this you'll see in the attachment is the compose and voice mail. Actually when you click on compose its open a page n if you click on voice mail its open the same page with recorder in it, purporting voice mail page is same as compose page but recorder is added in the voice mail, so i want to ask is it a conflicting issue of somethings between these two pages.
Another thing i tried and this is very strange, what happened one of my user, java is not installed, he is also using IE 6, its the same person,when i try your script, it don't work on his computer, I locally try java check script on his system. I simply use the condition if java is not installed then pop up a message, this local script works fine on Firefox, he also contain Firefox in his system, but when i try the script in IE it didn't show any message, the strange thing is this when i change the condition, if java installed then pop a message, then his IE pop up a message and is just shown as i click on compose page means i don't enter in the voice mail and it shows message two times but in Firefox until i click on the voice mail it didn't show any message , and i m unable to understand why it is happening, because he has no java at all.
Also the only tag that i supposed to set is the name parameter in the applet tag and i set it before trying your script.
So this is the whole story and its long enough :)
But thank you very much for your help
Thank You :)

Hi to all,
I come to know that (navigator.javaEnabled()) not actually check java in your system in IE, and i also known why it is throwing message when i change condition to (navigator.javaEnabled()), so any one tell me how can i check whether java is installed on your system or not in IE.
Thank you
