Olá.
Ao fazer o login na minha aplicação com o JAAS, gostaria de realizar algumas operações antes de entrar na página propriamente dita, e para isto uso um Filter.
Só que de vez em quando dá um erro 404, “the requested resource (/aplicacao/j_security_check) is not available”.
Coloquei um breakpoint nesta classe Filter e antes de terminar de executar totalmente o código dela, o browser já direciona para a página de erro.
web.xml
<filter>
<filter-name>securityFilter</filter-name>
