Olá pessoal,

Estou iniciando meus estudos de JSTL, e estou tendo alguns problemas para avançar.

Não consigo listar meus contatos pelo JSTL.

Erro:

Ha muitos erros ai, mas pelo q pude ver sao erros de nao axar as propriedades, vc mapeio certinho?

bffermino 9 de jan. de 2011

Ola Luxu,

Referente a mapeamento acredito não ter feito.
Como estou iniciando meus estudos não sabia de mapeamento, acreditava que era necessário somente adicionar os .jar na lib e então no Build Path, e rodar o serviço tom cat normalmente.
Apenas o que eu fiz.
