Answer 1

<dependency>
<groupId>com.sun.faces</groupId>
<artifactId>jsf-impl</artifactId>
<version>2.1.6</version>

is worked for me, you can change version as it release new versions.

Answer 2

Had the same problem. You probably used NetBeans to auto add this dependency with default 'compile' scope and it broke tomcat:

   <dependency>
        <groupId>javax</groupId>
        <artifactId>javaee-api</artifactId>
        <version>6.0</version>
    </dependency>

Use provided scope like here https://stackoverflow.com/a/10156854/1051834 If it does not help install a fresh tomcat and redeploy your project once again.
