Answer 1

In my case, using Oracle 12 and jboss 7.3, I solved using an empty String as param value. I don't understand why, but it works. This is my code:

String sql = "insert into customer (id,name,age) values (?1,?2,?3);
em = getEntityManager();
Query query = em.createNativeQuery(sql);
query.setParameter(1, getId());
query.setParameter(2, getName());
if (getAge() != null) {//getAge() return BigDecimal and map a NUMBER column type
    query.setParameter(3, getAge());
} else {
   query.setParameter(3, "");
}
