JSF + Tiles

Ola pessoal.

Estou desenvolvendo(ou tentando) um portal onde possui um layout com paginas jsp pra cada parte do layout ou seja,
uma pagina chamada head.jsp, conteudo.jsp e fooder.jsp
que montam o layout.

minha pagina index.jsp chama a pagina welcome.jsp onde soh tem o Bem vindo, q teria ser mostrada na parte do conteudo.

Mas quando rodo soh mostra o bem vindo e mais nada.
Meu tiles-defs.xml

meu web.xml
