http://www.guj.com.br/posts/list/6.java JForum - http://www.jforum.net Instancio uma Interface :
[code]
public interface GenericAction {
public String init();
public String save();
public String edit();
public String remove();
}
}[/code]

logo tento utiliza-la em minha Action:
[code]
public class PaisAction extends ActionSupport implements Preparable, GenericAction{
private PaisService paisService;
public PaisAction(PaisService paisService) {
super();
this.paisService = paisService;
}
...

}[/code]
Logo crio tambem uma interface para o service ..
[code]
public interface GenericService<Reg extends Identifiable<ID>, ID extends Serializable> {
public void save(Reg row);
public List<Reg> findAll();
public List<Reg> findAllByName();
public void delete(Reg row);
public void merge(Reg row);
public Long count();
}
[/code]
A referencia a ela no codigo:
[code]
public class PaisService implements GenericService<Pais, Integer>{
...
}
[/code]
Segue o applicationContext.xml:
[code]
<bean id="paisService" class="service.config.PaisService" scope="prototype"/>
<bean id="paisAction" scope="prototype" class="action.config.PaisAction">
<constructor-arg ref="paisService" />
</bean>
[/code]

quando tento chamar uma action da o seguinte erro:
[code]
Struts has detected an unhandled exception:

alguem sab como lidar com esse "problema" (ou soluçao)???????
Ja tentei instanciar o metodo GenericService no construtor de PaisAction e receboi a mensagem de erro dizendo que o metodo nao pode ser instanciado por ser uma interface (logica).. mas foi soh uma tentativa sem sucesso..
