Don't really know how to help you, but it looks like the Tomcat libraries haven't been located at runtime
so they're not on the classpath. Which IDE are you using? More importantly, why on earth, if you are a
beginner are you using JSF 1.1? Is this a corporate requirement? I wouldn't want to be using it.

I'm using Eclipse Helios.
Which JSF should I use and how to add Tomcat libraries to the classpath?

In you log it reads
"SEVERE: Both MyFaces and the RI are on your classpath. Please make sure to use only one of the two JSF-implementations."

So you have both the Sun reference implementation and the Apache MyFaces in you classpath. Remove the other.

I do not know why Brendan Healey thinks that the Tomcat libraries are missing. I do not see any errors that imply that.

And I personally would start with JSF 2.0 and with JSF 2.0 examples and in fact I did when I started using JSF a while ago.
