Do you mean
@ManyToMany(cascade={CascadeType.PERSIST, CascadeType.MERGE})
@JoinTable(name="user_group", joinColumns=@JoinColumn(name="uName",
referencedColumnName="id", nullable=false) @Column(length=128)),
inverseJoinColumns=@JoinColumn(name="gName", referencedColumnName = "id")
@Column(length=256)) private Set<Group> groupsField;
It's not correct. Could you tell me the correct one?
