Boa dia galera!
estou tendo um problema no meu projeto, pois estou seguindo a apostila da Caelum java web fj 21!
mas estou tendo problema no exercicio 9.7 - Exercícios: Criando nossas lógicas e servlet de controle
fiz as classes mas no console aprece o seguinte erro!
Servlet.service() for servlet [controlador] in context with path [/fj21-agenda] threw exception [Servlet execution threw an exception] with root cause
Desde de já o muito obrigado!
Rafael, blz!
Já fiz os exercícios desta apostila, não tive esse problema.
Posta o código pra eu tentar te ajudar.
Abs.
