isso acontece somente quando roda pelo apache… rodando o projeto pelo eclipse tudo vai normal…
a pergunta que faço a vocês é:
como posso adicionar linhas no log do apache? como quando usamos o System.out.printl(“ex”);
dei uma olhada e vi que tem o java.util.logging, mas pelo oq eu entendi eu crio um log/arquivo a parte… o que eu queria mesmo era adicionar linhas no log do propio apache
acredito que isso me ajude a ver aonde esta o meu problema mais facil… pq o nullpointer simplismente nao diz nada ;x
abraço
agradeço desde ja
