JSF project in Eclipse with Maven gives ClassNotFoundException for FacesServlet

I have created a Maven project in Eclipse. From the Project Aspects menu, I selected Dynamic Web Module, Java, and Java Server Faces. Added some dependencies from pom.xml like jsf-api and servlet-api. Then I wrote a simple Java bean and xhtml page that uses the bean.

When I create a war file with "maven clean install" and manually deploy it to Tomcat, it works as expected. But when I select Run on Server from Eclipse it gives the following error:

SEVERE: Servlet /testjsf1 threw load() exception

It seems the jsf libraries are not bundled as expected when run from Eclipse. Do you have any idea about the reason for this behavior?
