Bean declaring a passivating scope must be passivation capable.

Estou com problemas para levantar o Tomcat. Um erro é causado no TemaBean:

caused by: org.jboss.weld.exceptions.DeploymentException: WELD-000072: Bean declaring a passivating scope must be passivation capable. Bean: Managed Bean [class br.com.caelum.livraria.bean.TemaBean] with qualifiers [@Default @Any @Named]

Meu TemaBean:

package br.com.caelum.livraria.bean;

import javax.enterprise.context.SessionScoped; import javax.inject.Named;

@Named @SessionScoped //javax.enterprise.context.SessionScoped public class TemaBean {

private String tema = "vader";

public String getTema() { return tema; }

public void setTema(String tema) { this.tema = tema; }

public String[] getTemas() { return new String[]{"afterdark","afternoon","afterwork","aristo", "black-tie","blitzer","bluesky","bootstrap","casablanca", "cupertino","cruze","dark-hive","delta","dot-luv","eggplant", "excite-bike","flick","glass-x","home","hot-sneaks", "humanity","le-frog","midnight","mint-choc","overcast", "pepper-grinder","redmond","rocket","sam","smoothness", "south-street","start","sunny","swanky-purse","trontastic", "ui-darkness","ui-lightness","vader"}; }

}

Alguém com alguma idéia?

No aguardo,

Marcelo
