Senhores,

Sou iniciante em maven e estou penando pra resolver um problema com webapp.

O erro que está ocorrendo é o seguinte:


Grave: Servlet.service() for servlet [Faces Servlet] in context with path [/ViewSgp] threw exception
java.lang.UnsupportedOperationException
	at javax.faces.application.Application.getResourceHandler(Application.java:282)
	at javax.faces.webapp.FacesServlet.service(FacesServlet.java:303)

Isso ocorre quando eu acesso http://localhost:8080/App, parece que o sistema não está reconhecendo o welcome -file do web.xml, talvez pelo formato das páginas.

Se eu gerar um projeto e deixar o web.xml default e pagina index.jsp acessa normalmente.

Segue web.xml para análise:

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

	</servlet-mapping>
	<welcome-file-list>
		<welcome-file>home.jsf</welcome-file>
	</welcome-file-list>
</web-app>

Peço à ajuda de vocês pra resolver isso.

Grato.
