Following the model in tutorial1 I created a my persistent object as
follows:
public class OJBUser {
public int id;
protected String FirstName;
protected String LastName;
protected String Email;
protected String UserLogin;
}
In my DB, I the collumn is named "pkUserID" and thus I have mapped it in
the repository_user.xml:
<field-descriptor id="1"
name="id"
column="pkUserID"
jdbc-type="INTEGER"
primarykey="true"
autoincrement="true"
/>
Now, I am getting this error when running the the example, as it seems
the reflection code cannot find my id parameter in the object. Why?
