Hi Folks,
I am using Hibernate and Spring 1.2.1 for trying to map an one-to-many association between two simple classes (composition) and navigable in both sides. I mean, Person<->---------*PersonDetails.
The following lines, it shows the Java code I am testing.
Set<PersonDetail> personDetailSet = new HashSet<PersonDetail>();
PersonDetail personDetail1 = PersonDetail.Factory.getInstance();
personDetail1.setAddress("Lane1");
personDetail1.setEmail("xxxx@yyyyy.zz");
personDetail1.setTelf("112233");
personDetail1.setMobile("77777");
personDetailSet.add(personDetail1);
PersonDetail personDetail2 = PersonDetail.Factory.newInstance();
personDetail2.setAddress("Lane2");
personDetail2.setEmail("aaaa@bbbbbbb.cc");
personDetail2.setTelf("112233-2");
personDetail2.setMobile("777772");
personDetailSet.add(personDetail2);
Person person = Person.Factory.getInstance();
person.setName("Joe");
person.setSurname("Smith");
person.setAge(new Integer(33));
person.setCcnumber("11334112");
person.setSs(new Integer(33442222));
person.setPersonDetails(personDetailSet);
Person response = personDao.create(person);
When I run the code I always get the same stack trace and I have no clue where to start.
Please, drop a few words if you have any idea what's going on in my example.
Thanks.
NOTE: This is ONLY a sample test and my idea was test the cascade functionality.
