Pessoal,
Estou tendo alguns problemas para configurar um framework de DI + VRaptor + Shiro, tentei o Spring acabou que tive problemas e resolvi alterar para Guice, que estou tendo problemas tambem.
O Problema é o seguinte:
Criei um Provider como diz na documentação do Vraptor:
public class OpenGuiceProvider extends GuiceProvider {
ServletContext context;
@Override
protected void registerCustomComponents(ComponentRegistry registry) {
}
@Override
protected Module customModule() {
final Module module = super.customModule();
return new ServletModule() {
@Override
protected void configureServlets() {
super.configureServlets();
module.configure(binder());
install(new OpenShiroWebModule(context));
}
};
}
@Override
public void start(ServletContext context) {
this.context = context;
super.start(context);
}
}Neste Provider, instalo o modulo de integração do Shiro com o Guice.
[code]
public class OpenShiroWebModule extends ShiroWebModule {
public OpenShiroWebModule(ServletContext sc) {
super(sc);
}
@Override
protected void configureShiroWeb() {
bindRealm().to( OpenRealm.class );
bindConstant().annotatedWith(Names.named("shiro.loginUrl")).to("/index.html");
}
}[/code]
Porem ao executar o código, recebo o seguinte erro:
Grave: Exception starting filter vraptor

A parte do código onde da problema é no Shiro Modulo do jar de integração do shiro na linha 77:
bind(DestroyableInjectionListener.DestroyableRegistry.class).toInstance(registry);
Alguem poderia me ajudar a sanar esse problema?
Obrigado
