Hibernate Interceptor in Seam

[bvphadnis.bvphadnis.gmail.com]

Hi,

I am trying to write an interceptor for Entity beans to log CRUD actions. Can someone tell me how to implement a Hibernate interceptor in Seam?

Thanks for your time

The way I did it:

- Create a class that extends org.hibernate.EmptyInterceptor.

package myapp.service.util;

import java.io.Serializable;

import org.hibernate.CallbackException;
import org.hibernate.EmptyInterceptor;
import org.hibernate.type.Type;

public class EntityInterceptor extends EmptyInterceptor {

     @Override
     public void onCollectionUpdate(Object collection, Serializable key)
               throws CallbackException {
          super.onCollectionUpdate(collection, key);
     }
     
     @Override
     public boolean onSave(Object entity, Serializable id, Object[] state,
               String[] propertyNames, Type[] types) {
          boolean changed = false;
          /*
            put any changes on save here
          */
          return changed;
     }
}

- Configure it in your persistence file with the following line:

<property name="hibernate.ejb.interceptor" value="myapp.service.util.EntityInterceptor" />
