Olá Pessoal,
Estou criando uma aplicação que utilize JPA e JSF, pesquisei alguns exemplos no google e acabei construindo minha aplicação conforme o artigo do Urubatan, estou utilizando tomcat 6 + java 6 e jsf 1.2.
Tambem copiei os arquivos do toplink para a pasta lib do tomcat e editei o arquivo annotations-api.jar conforme explicado no artigo.
Ao executar minha aplicação(http://localhost:8080/lojateste/home.jsf) surge o seguinte erro:
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception

Alguem aqui já passou por isso?
Segue abaixo os arquivos de configuração:
