I have a page that uses java, I didn't write the code, don't know java, is there a way to check to see if java is enabled or not and then either open the java page or open a page where the user can go to download java?
If so could you please post a sample of the code or a url where I can get it.
Thanks

please check this example,

HTML Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Java Installed?</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script type="text/javascript">
function isJava(){
	if(!navigator.javaEnabled())
	{
		var message = confirm("You either have java disabled or you currently don't have java installed. Would you like to download java?");
		if(message)
		{
			window.location = "http://java.sun.com";
		}
	}
}
window.onload = isJava;
</script>
