My Java code...
Code:
public class Task {
private long id;
private String name;
private String code;
private Date expirationDate;
private List taskAttributes;
public Task() {
}
public String getCode() {
return code;
}
public Date getExpirationDate() {
return expirationDate;
}
public long getId() {
return id;
}
public String getName() {
return name;
}
public List getTaskAttributes() {
return taskAttributes;
}
public void setCode(String string) {
code = string;
}
public void setExpirationDate(Date date) {
expirationDate = date;
}
public void setId(long l) {
id = l;
}
public void setName(String string) {
name = string;
}
public void setTaskAttributes(List list) {
taskAttributes = list;
}
}
Code:
public class TaskAttribute {
private long id;
private Date expirationDate;
private Attribute attribute;
private Task task;
public TaskAttribute() {
}
public Attribute getAttribute() {
return attribute;
}
public Date getExpirationDate() {
return expirationDate;
}
public void setAttribute(Attribute attribute) {
this.attribute = attribute;
}
public void setExpirationDate(Date date) {
expirationDate = date;
}
public long getId() {
return id;
}
public Task getTask() {
return task;
}
public void setId(long l) {
id = l;
}
public void setTask(Task task) {
this.task = task;
}
}
Code:
public class Attribute {
private long id;
private String name;
private Date expirationDate;
public Attribute() {
}
public Date getExpirationDate() {
return expirationDate;
}
public long getId() {
return id;
}
public String getName() {
return name;
}
public void setExpirationDate(Date date) {
expirationDate = date;
}
public void setId(long l) {
id = l;
}
public void setName(String string) {
name = string;
}
}
My Test main class...
Code:
public class Test {
public static void main(String [] args) throws Exception {
Task task = new Task();
task.setName("cucho");
task.setCode("abc");
task.setExpirationDate(new Date(20040512));
Attribute attribute = new Attribute();
attribute.setName("cuchoAttribute");
attribute.setExpirationDate(new Date(20040512));
TaskAttribute taskAttribute = new TaskAttribute();
taskAttribute.setExpirationDate(new Date(20040512));
taskAttribute.setAttribute(attribute);
taskAttribute.setTask(task);
List taskAttributes = new ArrayList();
taskAttributes.add(taskAttribute);
task.setTaskAttributes(taskAttributes);
Configuration cfg = new Configuration().addClass(Task.class).addClass(TaskAttribute.class).addClass(Attribute.class);
SessionFactory sf = cfg.buildSessionFactory();
Session session = sf.openSession();
System.out.println("Saving instance");
session.saveOrUpdate(task);
System.out.println("Instance just saved");
}
}

and the output when I run the test...

Saving instance
Instance just saved
so... everything seems to be ok, i can connect to the db and create the tables using SchemeExport, etc, etc but when i check the tables in the database after executing the Test.java nothing is saved... they are all empty.
I'm not a DB specialist, so i neither don't know if the db desing is ok.
Thanks all for any possible hand !
