first steps with cometd-java

[michael....@googlemail.com]

Hi,

I try to get the cometd-java demo running. I have followed the
installation instructions
and after executing "mvn jetty:run" jetty (version 6.1.1) starts up
but throws several exceptions (see below).
Now jetty is running but I can't access anythin on port 8080 (404). It
seems to me that there's something
missing in the classpath. What do I need to add to the classpath and
where do I have to add it?

Thank you!

Michael

these are the exceptions thrown by jetty:
