Ao criar um domínio com WebCenter, se ao invés de utilizar às configurações padrões, resolver instalá-lo sem o managed server para economizar memória, você poderá ter o seguinte erro:

É porque o WebCenter entra em conflito com a aplicação de boas vindas. Para corrigir esse problema, é só realizar o undeploy da aplicação "FMW Welcome Page Application". Depois realize o redeploy da aplicação webcenter ou reinicie o servidor. Era um problema que já tive antes, mas tinha esquecido de repassar o conhecimento.
