    Use Deployjava.js to test whether java installed or not:

    Sample Code:

    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE> Deploy Java Test </TITLE>
</HEAD>
<SCRIPT LANGUAGE="JavaScript" src="deployJava.js">
</SCRIPT>
<script type="text/javascript">
function call()
{
    if (deployJava.versionCheck("1.6.0+") || deployJava.versionCheck("1.4") ||    deployJava.versionCheck("1.5.0*")) 
    {
        alert("Java is Enabled");
    } else 
    {
        alert("Java is Not Enabled");
    }
}
</script>
<BODY onload="call();">
</BODY>
</HTML>
