Need help getting through the LiftWeb Getting Started tutorial

I'm trying to get through the LiftWeb Getting Started Tutorial.

This is what I've done:

1. Downloaded and unpacked the tar-file.

2. (Here I tried to do开发者_如何学编程 sbt update as stated in the instructions, but it failed.)

3. Copied lift_blank/* to project root.

4. Then sbt update (successfully this time)

5. Copied the source code for Chat.scala and inserted the tag in webapp/index.html as instructed.

6. Executed sbt ~jetty-run

7. Opened a http://localhost:8080 in a browser.

But all I see is this:

which doesn't look like a chat-application to me.

What am I doing wrong?

I tried it my self and I must say that the tutorial isn't very clear about where to paste the div block.

Here's what I did in addition to the instructions on the tutorial page:

I pasted the given div snippet into the existing main div block of the index.html.

<div id="main" class="lift:surround?with=default;at=content">

<div class="lift:comet?type=Chat">
  <ul>
    <li>line</li>
  </ul>
</div>

</div>

This should do it.

After running jetty, I could use the simple chat app.

Here's a screen shot of what I am seeing after running sbt ~jetty-run

Hope that helps

Btw, it even works with lift_blank:
