Manipulate a List inside a foreach in a view

I have a doubt that it should be simple to solve, but I am not able to develop a logic, or even be doing the wrong thing.

Well, I have a table in which I scroll through a table called "categories" within this table. I have a relationship with another named "targets" as you can see below in the bean:

Destination.java

@Entity
@Table(name="destination")
@Multitenant
@TenantDiscriminatorColumn(name="tenant_id", discriminatorType=DiscriminatorType.INTEGER, contextProperty=PersistenceUnitProperties.MULTITENANT_PROPERTY_DEFAULT)
@NamedQuery(name="Destination.findAll", query="SELECT d FROM Destination d")
public class Destination implements Serializable {
    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    @Column(name="id_destination")
    private Long idDestination;

    @Column(name="tenant_id", insertable=false, updatable=false)
    private Long tenantId;

    @Column(name="appear_website")
    private Boolean dtAppearWebsite;

    @Lob
    @Column(name="description")
    private String dtDescription;

    @Column(name="highlight_website")
    private Boolean dtHighlightWebsite;

    @Column(name="name")
    private String dtName;

    @OneToOne(cascade=CascadeType.PERSIST)
    @JoinColumn(name="fk_streetview")
    private StreetView streetView;

    @OneToOne(cascade=CascadeType.PERSIST)
    @JoinColumn(name="fk_video")
    private Video video;

    @ManyToOne(cascade=CascadeType.REFRESH)
    @JoinColumn(name="fk_category")
    private Category categories;


    //Getters and Setters

Category.java

@Entity
@Table(name="category")
@Multitenant
@TenantDiscriminatorColumn(name="tenant_id", discriminatorType=DiscriminatorType.INTEGER, contextProperty=PersistenceUnitProperties.MULTITENANT_PROPERTY_DEFAULT)
@NamedQuery(name="Category.findAll", query="SELECT c FROM Category c")
public class Category implements Serializable {
    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    @Column(name="id_category")
    private Long idCategory;

    @Column(name="ct_active")
    private int ctActive;

    @Column(name="ct_name")
    private String ctName;

    @Column(name="tenant_id", insertable=false, updatable=false)
    private Long tenantId;

    @OneToMany(mappedBy="categories")
    private Set<Destination> destination;

    //Getters and Setters

Right! In my view I have a field in which I displayed the number of destinations linked to each category:

<c:forEach items="${category}" var="c">
    <tr>
        <td><a href="editCategory?id=${c.idCategory}">${c.ctName}</a></td>
        <!-- Campo no qual o numero de destinos é exibido por categoria-->
        <td>${categoryHasDestination}</td>
        <c:choose>
            <c:when test="${c.ctActive=='1'}">
                <td><span class="label label-success">Ativo</span></td>
            </c:when>
            <c:otherwise>
                <td><span class="label label-warning">Desativo</span></td>
            </c:otherwise>
        </c:choose>
    </tr>
</c:forEach>

So I've created a method that returns me the categories and also a list of the number of linked destinations in each category.

@RequestMapping("category")
public String getMenuCategory(Model mv) {
    List<Category> category = dashboardFacade.getCategoryList();
    List<Integer> size = new ArrayList<Integer>();

    for (Category categories : category) {
        Set<Destination> destinationList = categories.getDestination();
        int s = destinationList.size();
        size.add(s);
    }

    /Retorna uma lista com o numero de destinos para cada categoria
    mv.addAttribute("categoryHasDestination", size);

    //Me retorna todas as categorias
    mv.addAttribute("category", category);
    return "category/categoryList";
}

The problem is that in my view I have a foreach, that is, for each record the list is returned and not the number itself. The image below illustrates what I mean:

Thank you all for the help
