Unable to make ironpython run in browser with silverlight

Wed May 25 08:16:40 EDT 2011

Basically i am following this tutorial:
http://blog.jimmy.schementi.com/2010/03/pycon-2010-python-in-browser.html
According to it, this code should run fine:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
   "http://www.w3.org/TR/html4/strict.dtd">
<html>
  <head>
  <script type="text/javascript"
          src="http://gestalt.ironpython.net/dlr-20100305.js"></
script>
  <script type="text/python" src="http://github.com/jschementi/
pycon2010/raw/master/repl.py"></script>
  </head>
  <body>
    <script type="text/python">
      window.Alert("Hello from Python!")
    </script>

  </body>
</html>

And in fact, it does, for example here: http://ironpython.net/browser/examples/pycon2010/start.html

You will see it if you have silverlight installed.

But the problem is that when I try to make the same code run on my PC,
I can't do it. I create a text file, copy this code there, save it as
test.html, and run with firefox, but nothing happens. Code does not
execute, i just get a blank page. I can't understand the reason why
the same code runs here: http://ironpython.net/browser/examples/pycon2010/start.html,
but not on my PC, given that it is a client side code, and not the
server side.

And there is nothing written in firefox error console, when I run it
locally.
But if I host it on my webhosting account, then I get this error:

Error: uncaught exception: [Exception... "Component returned failure
code: 0x80004005 (NS_ERROR_FAILURE) [nsIXMLHttpRequest.send]"
nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: http://
sitename .com/silverlighttest.html :: DLR_DownloadResource :: line 15"
data: no]

I uploaded the html file I am using here: http://www.filedropper.com/silverlighttest
But it just a text file with that code with extension changed
to .html.

What can I do?
