Pom Dependency in a JSF project with Richfaces and MyFaces

Question

I want to build a JSF project with MAVEN. I tried to add the all dependencies i needed. Each time I get the errors.

<dependencies>
    <dependency>
        <groupId>org.richfaces</groupId>
        <artifactId>richfaces-bom</artifactId>
        <type>pom</type>
        <version>4.2.2.Final</version>
    </dependency>
    <dependency>
        <groupId>org.apache.myfaces.core</groupId>
        <artifactId>myfaces-impl</artifactId>
        <version>2.0.2</version>
    </dependency>
    <dependency>
        <groupId>org.apache.myfaces.core</groupId>
        <artifactId>myfaces-api</artifactId>
        <version>2.0.2</version>
        <scope>compile</scope>
    </dependency>

</dependencies>

What should I add to this POM so that my project works as a real JSF project?

P.S I added the right richfaces dependencies. I got deploy problems on websphere like.

Caused by: javax.faces.FacesException: java.lang.UnsupportedOperationException
    at com.sun.faces.config.ConfigureListener.contextInitialized(ConfigureListener.java:387)

The Richfaces dependency you are using is just a bom - it lists a set of compatible "real" dependencies and should be used in the dependencyManagement section of your pom:

  <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>org.richfaces</groupId>
        <artifactId>richfaces-bom</artifactId>
        <version>4.2.2.Final</version>
        <type>pom</type>
      </dependency>
    </dependencies>
</dependencyManagement>

In the dependencies, you should have the implementation, like this:

<dependencies>
  <dependency>
    <groupId>org.richfaces.ui</groupId>
    <artifactId>richfaces-components-ui</artifactId>
    <!--version>4.2.2.Final</version-->
  </dependency>

  <dependency>
    <groupId>org.richfaces.core</groupId>
    <artifactId>richfaces-core-impl</artifactId>
    <!--version>4.2.2.Final</version-->
  </dependency>
<dependencies>

The version element of the dependencies is redundant, if you are using the bom. You are better off removing it, as you may unwillingly overrride the bom setting.

EDIT: the error you are getting looks like a configuration issue to me. Not sure what may have caused it. My advice is to start with a working webapp example and then add additional dependendcies. My favorite way is to let maven geneare a webapp from archetype:

mvn archetype:generate

you will then see a long list of possibl archetypes. Try something with a JSF in it, like jsf-weld-servlet-webapp or weld-jsf-jee or richfaces-archetype-simpleapp. These are known to work, and you can sample the pom and the rest of the project to see what may be missing.
