mande uma imagem com todas suas bibliotecas… acho que esta faltando alguma!
Opa JonathanSSantos! Coloquei a foto do meu diretorio lib.
caso fique muito pequena ai vai o link da foto no picasa:
http://picasaweb.google.com.br/lh/photo/kuMFKlPI3eISWcjDyCRpCA?feat=directlink
Verifica se as bibliotecas do apache estao corretas e se possui todas libs 
Opa JonathanSSantos! Foi mal a demora em responder, é que aqui na empresa estamos com o prazo apertado aí tive que dar prioridade a outras coisas.
Eu adicionei as bibliotecas do apache tanto no ditretório lib como no build path e não mudou o erro.
