I think you are trying to enter the ID of an Employee record and have
that id become the Employee object when the User is processed by
Struts. What you have now is Struts will create a blank Employee
object and call user.setEmployee() and then will set the id property
of that Employee, employee.setId(). I am not sure about your
@JoinColumn annotation, I would have to look it up to see if there is
something there that could be messing things up. I usually just use
@OneToOne(mappedBy = "xxx") on one side and just a plain @OneToOne on
the other side and let Hibernate figure out the column names. But you
may need your column names to follow a specific convention or they are
existing database tables.
If you are trying to associate an Employee with a User with your form
then I suggest the following:
* Create a TypeConverter that can convert an Employee to a String by
doing (String)employee.getId(). The other side of the conversion to
an Employee takes the String id and looks up the Employee record in
the database.
* Register your TypeConverter for the Employee class
* Now your field name is just user.employee and you enter the ID
value. (It could be a select list with names as the value and ids as
the key that gets submitted)
I suppose it is possible that you want to create a new employee
record, set its id manually and have the new employee record save with
the User, but I doubt it. That would require some fancy id
annotations on the Employee class. Most likely you need to look up
TypeConversion in Struts. I think there are older posts here or on
the Struts list that I have described the process in more detail.

Hi
Please Help me out here
What Iam trying to do is one-to-one Mapping in Appfuse2 Struts type
Steps that I did
I have an Employee model
and im trying to map this employee to User.
I have created in User as follows
---
-------
Private Employee employee;
@OneToOne(cascade=CascadeType.All)
@JoinColumn
(name="Fk_Employee_Id",referencedColumnName="Pk_Employee_id")
public Employee getEmployee {
return employee;
}
public void setEmployee(Employee employee {
this.employee = employee;
}
----
----------------
in the UserForm page I have added as follows
<s:textfield key="user.employee.id" cssClass="text large"
required="true"/>
when i open the userForm and try to add new record the record is
saving fine
and it shows user object as saved successfully but the value which i
entered
in the employee feild was not saving in the database.
Iam unable to figure it out.
Please Help me whether iam missing any thing
or
Please Can you send me an example for One-to-One Mapping .
Thanks For ur help in advance
