In MyEclipse 6.0.1, the JPA validator does not seem to validate entities that are inner classes of other entities. In the code below, the comments show the warnings raised by the validator. This code represents a valid entity relationship, and is handled correctly by Hibernate. If the Inner class is moved outside of the Outer class, the validator works correctly.

Outer.java

import java.util.*;
import javax.persistence.*;

@Entity public class Outer {
    @Entity public static class Inner {
        @Id @GeneratedValue protected Long id;

        @ManyToOne protected Outer outer;

        public Long getId() {
            return id;
        }

        public Outer getOuter() {
            return outer;
        }

        public void setOuter(Outer outer) {
            this.outer = outer;
        }
    }

    @Id @GeneratedValue protected Long id;

    // MappedBy specified for inners does not exist on the target entity class
    // Target Outer.Inner.class is not an entity
    @OneToMany(mappedBy = "outer") protected Set<Inner> inners;

    public Long getId() {
        return id;
    }

    public Set<Inner> getInners() {
        return inners;
    }

    public void setInners(Set<Inner> inners) {
        this.inners = inners;
    }
}

I was able to reproduce this warning at my end as well. I have logged this for my dev team. I’ll get back to you with an update as soon as possible. Thank you for bringing this up.

While doing some additional testing, I noticed that the validator also ignores fully-qualified annotations. The code below generates no errors or warnings from the validator.

Outer.java

import java.util.*;

@javax.persistence.Entity public class Outer {
   @javax.persistence.Entity public static class Inner {
      @javax.persistence.Id @javax.persistence.GeneratedValue protected Long id;

      @javax.persistence.ManyToOne protected Outer outer;

      public Long getId() {
         return id;
      }

      public Outer getOuter() {
         return outer;
      }

      public void setOuter(Outer outer) {
         this.outer = outer;
      }
   }

   @javax.persistence.Id @javax.persistence.GeneratedValue protected Long id;

   @javax.persistence.OneToMany(mappedBy = "outer") protected Set<Inner> inners;

   public Long getId() {
      return id;
   }

   public Set<Inner> getInners() {
      return inners;
   }

   public void setInners(Set<Inner> inners) {
      this.inners = inners;
   }
}

Can you go to MyEclipse > Installation Summary > Installation Details and paste the installation information here for me as well. I just want to make sure all this is being tested on the same version of MyEclipse as yours.

Thanks for your help. I’ll try to get this fixed asap.

[Erik Mattheis]

Any update on this issue?

[Loyal Water]

IronDuck,
Some other high priority items had to go into 6.5 that may cause this to get pushed out to the next release, sorry about that.
