JBoss SeamAction: Could not instantiate Seam component. NEED HELP

mpsantos · Janeiro 21, 2009, 10:03pm

Olá pessoal!

Eu estou a criar uma web application com a framework JBoss Seam e estou com problemas a criar uma Seam Action. Estou a utilizar o Eclipse 3.4 Ganymed, o servidor aplicacional JBoss AS 4.2.3 e o JBoss Seam 2.1.1. Como meio de deployment estou a utilizar WAR file. Utilizei os JBoss Tools para criar o projecto e criei a action Ping que o manual de referencia diz para criar. E correu tudo direitinho Mas como eu queria utilizar a Action para persistir dados, acrescentei a anotação “@Stateless” para poder utilizar o EntityManager para poder persistir uma Entity.

@Stateless
@Name("ping")
public class Ping implements IPing { .... }

@Local
public interface IPing {....}

quando faço isso recebo a seguinte excepção:
