Redirect com JSF 2.2 não funciona quando tenho compilo Rest WS [RESOLVIDO]

AlexSlender · Fevereiro 26, 2016, 11:11pm

Boa noite pessoal, gerei um projeto com Maven pra utilizar wildFly e JSF, mais tarde integrei também o primefaces. Escolhi a opção no maven que gerar as classes de exemplo, testei a comunicação do Rest, e tudo certo. Comecei a desenvolver, mas acontece que minha classe de Login só redireciona se eu não compilar a minha class Rest. OBS.: não estou usando web.xml

Consegui entender o problema. Eu tinha um filtro servlet também escutando todas requisições no diretório /restricted, quando eu não compilava o filtro, também estava funcionando, daí bastou em renomear o meu diretório restricted para home, e mudar no filtro para “/home”. Dessa forma funcionou! Não entendi bem, mas é como se quando eu estava com filtro o webservice “/rest” estava entrando em conflito com o “/restricted” por começar com os caracteres “rest” também. Enfim se alguém puder explicar isso, seria grato.

RESOLVIDO!

Alex, blza? Estou com o mesmo problema no Struts 2 com RestEasy. Não consigo executar o web service, o Struts está “interceptando” todas as chamadas. Esses filtros que você falou, estão no web.xml?
