Well...
>From the tutorial...
public class Product
{
/** Artificial primary-key */
private Integer id;
/** price per item*/
private Double price;
/** stock of currently available items*/
private Integer stock;
/** product name*/
private String name;
/* Getters and Setters not shown for tutorial */
}
CREATE TABLE product
(
id INTEGER PRIMARY KEY,
name VARCHAR(100),
stock INTEGER,
price DOUBLE
)
<class-descriptor
class="org.apache.ojb.tutorials.Product"
table="PRODUCT"
>
<field-descriptor
name="id"
column="ID"
primarykey="true"
autoincrement="true"
/>
<field-descriptor
name="name"
column="NAME"
/>
<field-descriptor
name="price"
column="PRICE"
/>
<field-descriptor
name="stock"
column="STOCK"
/>
</class-descriptor>
...
Then after you have stored a product using transction.commit() (you said you were
using odmg) you should be able to get the unique id/primary key from myProduct.id...
See the tutorials at http://db.apache.org/ojb/user-docs.html for more info :)
Good Luck,
Rob :)
