Hi Everyone,
I am using ManyToMany bidirectional relationship, fragment of code is given
below for help:
In One Entity i am coding as:
@ManyToMany(cascade=CascadeType.REFRESH, fetch=FetchType.EAGER)
@JoinTable(name="trd_t_sess_nommem",joinColumns =
@JoinColumn(name="trs_trnsessnid_n_fk"),inverseJoinColumns =
@JoinColumn(name="tnm_nommemid_n_fk"))
public Set getNominatedmembersentity(){
return nominatedmembersentity;
}
/**
* @param nominatedmembersentity the nominatedmembersentity to set
*/
public void setNominatedmembersentity(
Set nominatedmembersentity) {
this.nominatedmembersentity = nominatedmembersentity;
}
At other entity i am coding as given below:
@ManyToMany(mappedBy="nominatedmembersentity")
public List getTrainingsessionentity() {
return trainingsessionentity;
}
But at the built time i am receiving the following error:
--- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM ---
ObjectName: persistence.units:ear=training.ear,jar=training.jar,unitName=intro
State: FAILED
Reason: javax.persistence.PersistenceException:
org.hibernate.HibernateException: cannot simultaneously fetch multiple bags
I Depend On:
jboss.jca:service=DataSourceBinding,name=PostgresDS
