Alterar sistema de log do hibernate[Resolvido]

Mikhas 19 de fev. de 2010

O SLF4J é uma “interface” para frameworks, como o hibernate, poderem usar Logs sem se preocupar com o Framwork de log que esta sendo utilizado. É como se fosse um adaptador de logs.

Da uma olhada nesse link
http://www.slf4j.org/manual.html#swapping

nathanpsouza:
galera eu queria mudar o slf4j que eh padrao do hibernate para commons-logging, que eh oq a minha aplicação toda ta usando, ja googlei a respeito mas não axei algo relevante de como fazer

Outra opção é deixar de usar o commons-logging na sua aplicação e usar o slf4j que é mais moderno , simples, e rápido.

nathanpsouza 19 de fev. de 2010

como eh uma aplicação de testes, fiz isso, e mudei a versao do slf4j para a versao 1.5.2, funcionou perfeitamente :}
