ClassNotFoundException Tomcat 7 Server

Question

I'm getting issues when I try to load something on my Tomcat 7 Server via Eclipse. I already downloaded an example and tried that one, but in my browser it only shows me that the resource is not available.

This is what i got when i run the example on my server. I cant fix the ClassNotFoundException. Does anyone got an idea?

Also it says 2 lines above the second ClassNotFoundException, "SCHWERWIEGEND: Servlet /0001 threw load() exception" but /0001 is another Project in the same workspace.

Thanks.

Answer 1

you need to compile your code cause file (.class) does not generate

Answer 2

Having that $-thingy verbatim with the ClassNotFoundException suggests the conjecture, that ${jsf-listener} is a non-resolved placeholder expression, so that this class is not found. So "jsf-listener" might be missing from some configuration. It is just a conjecture though.

Error configuring application listener of class ${jsf-listener} java.lang.ClassNotFoundException: ${jsf-listener}

Answer 3

Your artifact for Tomcat not containing "org.atmosphere" library. Check the way how you build WAR file. In case of Maven you need to add library as compiled dependency.
