Hi,

I have three entities ClassA, ClassB and ClassC.

ClassA {
 ...
 @Id
 @GeneratedValue
 @Column(name = "a_id")
 private long id;
 ...
 @OneToMany(cascade={CascadeType.ALL})
 @JoinColumn(name="a_id")
 private List<ClassB> bbb;
 ...
}

ClassB {
 ...
 @ManyToOne
 private ClassC ccc;
 ...
}

ClassC {
 ...
 private String name;
 ...
}

I want to filter by hibernate criteria ClassA by 'name' member of ClassC. So I want to obtain by hibernate criteria list of ClassA objects which have inside ClassC objects with specified name. Problem is that access to ClassC objects is through ClassB list.

I tried something like this but it does not work:

crit.createCriteria("bbb").createCriteria("ccc").add(Restrictions.ilike("name", name, MatchMode.ANYWHERE));

I will be grateful for help.
