Error "java.lang.ClassNotFoundException: org.springframework.core.enums.LabeledEnum" when creating select via spring form tags

Question

In my current spring project, I am genarating a form fot data input based on this jsp code:

<jsp:include page="../../common/cadastrar.jsp">
    <jsp:param name="entity" value="Pagina"/>
    <jsp:param name="arguments" value="nome"/>
    <jsp:param name="arguments" value="titulo"/>
    <jsp:param name="arguments" value="descricao"/>
    <jsp:param name="file" value="capa"/>
    <jsp:param name="select" value="Pagina"/>
    <jsp:param name="select" value="Produto"/>
</jsp:include>

the param select is translated in common/cadastrar.jsp as:

            <c:forEach var="item" items="${paramValues.select}">
                <p>
                    <label for="${item}">${item}</label>
                    <form:select path="${item}.id" class="form-control">
                        <form:option value="" label="" />
                        <c:forEach var="option" items="${values[item]}">
                            <form:option value="${option.id}" label="${option.nome}" class="form-control"/>
                        </c:forEach>
                    </form:select>
                </p>
            </c:forEach>

but right now, when I run the application and try open this page, I get this error:

the entity class associated to this view is that:

@Entity
@Table(name="pagina")
public class Pagina extends Entidade {

    @Id
    @Column(name = "id")
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    private Integer Id;

    @Column(name = "nome", unique=true)
    private String nome;

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

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

    @OneToOne( fetch = FetchType.EAGER )
    @JoinColumn(name="parent_page")
    private Pagina pagina;

    @OneToOne( fetch = FetchType.EAGER )
    @JoinColumn(name="parent_product")
    private Produto produto;
}

Anyone can tell me why is this happening and how to solve?

you are missing spring-core library in your runtime classpath

I recheck my pom.xml and this library is listed correctly. ALso, inside the generated war file, this library is inside the web-inf/lib directory. – Kleber Mota Jul 17 '14 at 19:53
can you see it available at runtime ? – jmj Jul 17 '14 at 19:54
as I said, the library is available in the WEB-INF/lib directory. what you mean about available at runtime? – Kleber Mota Jul 17 '14 at 19:56
if you expand that jar and try to find this class, does it exist in that jar / – jmj Jul 17 '14 at 19:59
Note that spring-core v3 has it but v4 does not. In my case another dep was bumping spring-core to v4. – Ben Challenor Aug 29 '14 at 17:06

I solve this problem adding this lines to my pom.xml:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>4.0.3.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-oxm</artifactId>
            <version>4.0.3.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>4.0.3.RELEASE</version>
        </dependency>
    </dependencies>
</dependencyManagement>
