thanks help!

using mvn clean install -u

just add javax.servlet api compile time dependencies. don't need include in build, it's provided target servlet container.

your current pom suggests you're deploying barebones servlet container (tomcat, jetty, etc) instead of full fledged java ee application server (wildfly, tomee, glassfish, liberty, etc), otherwise you'd have run classloading-related trouble providing jsf along webapp instead of using container-provided one.

in case, adding below dependency should servlet 3.1 container tomcat 8:

<dependency>     <groupid>javax.servlet</groupid>     <artifactid>javax.servlet-api</artifactid>     <version>3.1.0</version>     <scope>provided</scope> </dependency> 

or if you're targeting older servlet 3.0 container tomcat 7, change <version> 3.0.1 (note: there's no 3.0 due mistake on side).

if happen deploy java ee 7 application server wildfly 8, use below dependency instead. covers entire java ee api, including javax.servlet (and javax.faces, you'd remove individual jsf api/impl dependencies):

<dependency>     <groupid>javax</groupid>     <artifactid>javaee-api</artifactid>     <version>7.0</version>     <scope>provided</scope> </dependency> 

also here, if you're targeting older java ee 6 application server jboss 7, change <version> 6.0.
