@Size annotation not recognized (JPA)

问题

I want to validate the length of a String before trying to insert/update the entity to the Database.

@Size(min = 1, max = 45)
@Column(name = "name", nullable = false, length = 45)
private String name;

My problem is the @Size annotation is not being recognized using NetBeans 7.3, JDK 1.6, EclipseLink (JPA 2.0).

Is there an alternative to this ?

Try to include

<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>1.1.0.Final</version>
</dependency>
