Validation constraint in @Embedded class

Hi all.

I need to validate the fields of an embedded-annotated class.

I have the following structure:

Code:

@Entity
@Table(name = "table_A", schema = "my_schema")
public class A implements Serializable {

   private B b = null;

   @Embedded
   public B getB() {
      return b;
   }

   public void setB(B b) {
      this.b = b;
   }
}

@Embeddable
public class B implements Serializable {

   private String field = null;

   @Column(name = "b_field")
   @Length(min = 5, max = 10)
   public String getField() {
      return field;
   }

   public void setField(String field) {
      this.field = field;
   }
}

When I create an A object with a B object with a 'field' field length less than 5 or greater than 10, validator does not detect the constraint violation... Example:

Code:

A a = new A();
B b = new B();
b.setField("");
//b.setField("string longer than 10 characters");
a.setB(b);

I know my validation configuration is right because if I try to validate other fields in A class, but not @Embeddable, it rights fine.
Is there any problem with @Embeddable fields validation?

Hi,

have you tried to add the @Valida annotation to getB(). You will have to tell validator that this object reference have to be validated as well.

Yes. I have annotated getter method with @Valid.

But it still failing.

Any idea?

Ummmm, I must be stupid...

I have tried it again, and now it works (with @Valid annotation). i don't know why the last time I tried it did not work... Perhaps I was drunked...

Thanks.

Good to hear that it works now. I was about to ask for log messages, etc ;-)

It doesn't get run from the JSF validation phase but only via JPA just before persist. Is there any way to get it to run via JPA validation?
