Glassfish console admin

Não estou conseguindo entrar no console admin do glassfish. Instalei o glassfish e configurei a porta de admin 4848, padrão de instalação. Consigo startar o glassfish, mas ao tentar acessar o console admin pelo localhost:4848, ele entra mas só aparece uma mensagem de copyright: Copyright © 2005, 2011, Oracle and/or its affiliates.
