I am using WSO2 Application Server. When trying to deploy a WAR file build with JSF java.lang.ClassNotFoundException: javax.faces.webapp.FacesServlet is thrown on WSO2 AS. I have 3 questions;
For further details I'll paste the error log here.

Since others can benefit from this answer, I will post my findings;
This exception is thrown because WSO2 AS is not bundled with JSF. JSF comes as an additional feature that can be installed from the online Carbon p2 repository.
Name: WSO2 Carbon - J2EE Runtime Environment Identifier: org.wso2.carbon.as.runtimes.j2ee.feature
Refer this link for more details.
Already answered. Tomcat doesn't support it natively.
TomEE could have used. But not all web applications are using Java EE packages. WSO2 AS provides a way to enabling additional packages only for selected webapps through a webapp-classloading.xml.
For example if you put a webapp-classloading.xml file inside the META-INF folder, you will override the default settings and only the classloading environments defined in that XML file are exposed to the web application.
