Hi

I have 3 entities(EntityA,EntityB,EntityC).

EntitiyA has a composite primary key (id,version,instance)
EntitiyC has a composite primary key (id,version,instance)

EntitiyB has a composite primary key of the other two entities (EntitiyA .id,EntitiyA .version,EntitiyC.id ,EntitiyC .version,EntityB.version);

So entityB has composite primary key pointing to 2 entities.Also it has its own column (EntityB.version) as part of the same composite primary key.

I tried like this on entityA:
@OneToMany(mappedBy = "entityA", cascade = CascadeType.ALL, fetch = FetchType.EAGER)
private List<EntitiyA > entityList = new ArrayList<EntitiyA >();

On EntityB:
It is manytoOne relationship from EntityB to EntityA
@ManyToOne
@JoinColumns({
@JoinColumn(name="id", referencedColumnName ="id", insertable=false, updatable=false),
@JoinColumn(name="version", referencedColumnName ="version", insertable=false, updatable=false)
})
private EntitiyA entityA;

It is a onetoone relationship from entityB to entityC
@OneToOne(fetch=FetchType.EAGER)
@JoinColumns({
@JoinColumn(name="id", referencedColumnName="id", insertable=false, updatable=false),
@JoinColumn(name="version", insertable=false, referencedColumnName="version", updatable=false)
})


But it give me mapping error.It asks me that all primary key should be part of foreign key.

Please help.
