Mysql + hibernate duvida

opa! Pessoal,

fiz uma aplicacao pequena para testar apenas um recurso com o hibernate + java, porem estou tendo prolema no foreign, alguem sabe dizer o que fiz de errado, abaixo a mensagem de erro:

SEVERE: Cannot add or update a child row: a foreign key constraint fails (`beginhibernate/advert`, CONSTRAINT `FK_advert_user` FOREIGN KEY (`aduser`) REFERENCES `advert` (`aduser`) ON DELETE CASCADE ON UPDATE CASCADE) org.hibernate.exception.ConstraintViolationException: could not insert: [br.com.bean.Advert] at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:71) at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:43) at org.hibernate.id.insert.AbstractReturningDelegate.performInsert(AbstractReturningDelegate.java:40) at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:2108) at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:2588) at org.hibernate.action.EntityIdentityInsertAction.execute(EntityIdentityInsertAction.java:48) at org.hibernate.engine.ActionQueue.execute(ActionQueue.java:248) at org.hibernate.event.def.AbstractSaveEventListener.performSaveOrReplicate(AbstractSaveEventListener.java:290) at org.hibernate.event.def.AbstractSaveEventListener.performSave(AbstractSaveEventListener.java:180) at org.hibernate.event.def.AbstractSaveEventListener.saveWithGeneratedId(AbstractSaveEventListener.java:108) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.saveWithGeneratedOrRequestedId(DefaultSaveOrUpdateEventListener.java:186) at org.hibernate.event.def.DefaultSaveEventListener.saveWithGeneratedOrRequestedId(DefaultSaveEventListener.java:33) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.entityIsTransient(DefaultSaveOrUpdateEventListener.java:175) at org.hibernate.event.def.DefaultSaveEventListener.performSaveOrUpdate(DefaultSaveEventListener.java:27) at org.hibernate.event.def.DefaultSaveOrUpdateEventListener.onSaveOrUpdate(DefaultSaveOrUpdateEventListener.java:70) at org.hibernate.impl.SessionImpl.fireSave(SessionImpl.java:535) at org.hibernate.impl.SessionImpl.save(SessionImpl.java:523) at org.hibernate.impl.SessionImpl.save(SessionImpl.java:519) at br.com.dao.AdvertDAO.create(AdvertDAO.java:13) at br.com.teste.PostAdvert.main(PostAdvert.java:32)

aqui minhas tables com o foreign key:

CREATE TABLE `link_category_advert` ( `category` int(10) unsigned NOT NULL default '1', `advert` int(10) unsigned NOT NULL default '1', PRIMARY KEY (`category`,`advert`), KEY `category` (`category`), KEY `advert` (`advert`), CONSTRAINT `FK_link_advert_category` FOREIGN KEY (`category`) REFERENCES `link_category_advert` (`category`) ON DELETE CASCADE ON UPDATE CASCADE, CONSTRAINT `FK_link_category_advert` FOREIGN KEY (`advert`) REFERENCES `link_category_advert` (`advert`) ON DELETE CASCADE ON UPDATE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=latin1

CREATE TABLE `advert` ( `id` int(10) unsigned NOT NULL auto_increment, `message` varchar(45) default NULL, `title` varchar(45) default NULL, `aduser` int(10) unsigned NOT NULL default '1', PRIMARY KEY (`id`), KEY `aduser` (`aduser`), CONSTRAINT `FK_advert_user` FOREIGN KEY (`aduser`) REFERENCES `advert` (`aduser`) ON DELETE CASCADE ON UPDATE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=latin1

alguma dica?
