Question

For my first steps into Lift I just started with this tutorial but it won’t work for me. Instead of the simple chat app I only get these two exceptions:

Error processing snippet: comet
Reason: Comet Component not found

and

Error processing snippet: ChatIn
Reason: Class Not Found

Here is the directory structure of my compiled webapp:

But as you can see, there are the compiled .class files for Chat, ChatServer and ChatIn, so what’s wrong?

Please bring this question to the Lift Google group: https://groups.google.com/forum/#!forum/liftweb

It’s likely that your Boot.scala doesn’t contain the correct information, but without the source, it’s tough to figure out the issue.
