Question

    ....        
    @OneToMany(mappedBy=\"menu\", fetch=Fetc         


        

Answer 1

The elements of a Set cannot be accessed by index. You will need to add methods which return a List wrapping your set.

@Component
@Entity
@Table(name="menu")
@Configurable
public class Menu implements Serializable{      
    ....        
    @OneToMany(mappedBy="menu", fetch=FetchType.EAGER)
    private Set voceMenus; 

    public Set getVoceMenus() {
        return voceMenus;
    }

    public void setVoceMenus(Set voceMenus) {
        this.voceMenus = voceMenus;
    }

    //bind to this
    public List getVoceMenusAsList(){
        return new ArrayList(voceMenus);
    }
    .....   
}

JSP:

 
     Menu id
       
     ...... 
                
        
             .....
