        Collection<RuleGroupRelation> attachedRuleGroupRelationCollection = new ArrayList<RuleGroupRelation>();
        for (RuleGroupRelation RuleGroupRelationCollectionRuleGroupRelationToAttach : RuleApplGroupMst.getRuleGroupRelationCollection()) {
            RuleGroupRelationCollectionRuleGroupRelationToAttach = em.getReference(RuleGroupRelationCollectionRuleGroupRelationToAttach.getClass(),RuleGroupRelationCollectionRuleGroupRelationToAttach.getRgrSrgKey());

I got the answer,

In My Case, i have created the user defined method in JPAController Class as below,

public void create_custom(RuleApplGroupMst RuleApplGroupMst) {
    EntityManager em = null;
    try {
        utx.begin();
        em = getEntityManager();
        em.persist(RuleApplGroupMst);
        utx.commit();
    }  catch (Exception ex) {}

and then declare OneToMany Relationship in Entity Bean as,

@OneToMany(cascade = CascadeType.ALL,mappedBy = "ragmSrgKey")

and then i call create_custom method by managed bean.

It works with all type(including BigDecimal) of Primary/Reference Key.
