Greetings!
Say I have a class MyClass it looks like this:
public class MyClass {
private int id;
private String name;
private List<Integer> myIntegers = new ArrayList<Integer>;
/* getters and setters omitted ... */
}
What options do I have if I want to persist this class using OJB?
The List<Integer> is causing me problems since it is not a pesistent
entity class.
Requirements impede me from just putting it into one field and use a
IntList2VarcharFieldConversion.
Requrements want me to have the List<Integer> data in a separate
database table.
But I just cant figure out how to map this.
Here's my tables (I am using MySQL):
CREATE TABLE `MY_CLASS` (
`id` int(10) unsigned NOT NULL auto_increment,
`name` varchar(255) NOT NULL,
PRIMARY KEY (`id`)
);
CREATE TABLE `ITEMS` (
`my_class_id` int(10) unsigned NOT NULL,
`item_id` int(10) unsigned NOT NULL,
PRIMARY KEY (`my_class_id`, `item_id`)
);
Thankful for any suggestions.
