Swfobject, what if java's disabled?

i’m trying to figure out the whole swfobject thing…this is what i have so far…

</head>

<script type="text/javascript" src="swfobject.js"></script>

<div id="flashcontent"> <!-- this is where the alternative content goes -->
    This is the alternative content...if the user doesn't have flash, this should show up!
</div>

<script type="text/javascript">
    var so = new SWFObject("test.swf", "test", "600", "400", "7", "#0046ff");  
    so.write("flashcontent"); <!-- writes to flashcontent...if the user has flash, it replaces all the alternative content -->
</script>

<body>
</body>
</html>

it seems to be working fine…but i have two questions.

  1. hwo exactly do i go about doing the bypassing the swfobject if there is a system problem? like, what do i do with this?
    <a href=“mypage.html?detectflash=false”>Bypass link</a>

  2. and also, is there anything i can do in case the user has java disabled? i want to make sure that there is a very small chance that the user won’t be able to see the site.
