Somos três pessoas desenvolvendo um projeto JSF e não estamos no JSF antes. Estranhamente, com os mesmos dados verificados no SVN, um dos membros da equipe recebe um erro 404 toda vez usando o Tomcat 7.0.27.

No momento em que o Tomcat (usado dentro do Eclipse) é iniciado, o seguinte log é gravado:

Estamos usando o Mojarra 2.0.3 como JSF-Implementation que foi incluído pelo Eclipse no projeto (e presumivelmente no caminho de classe).

Na verdade, há uma entrada paracom.sun.faces.config.ConfigureListener emweb.xml

<listener>
     <listener-class>com.sun.faces.config.ConfigureListener</listener-class>
</listener>

Alguém tem algum ponto de partida para procurar o erro? Além disso, se informações adicionais forem necessárias, por favor me avise.
