j.sunilkumar,
You need to use a getter to retrieve the value. You seem to using a setter. I would suggest you go through a Java tutorial to understand how to user getters and setters.

thanks for your good response my problem is Aftergenenerating artifacts two classes are produced by the eclipse
those are
1)Employee
2)EmployeeID
if i wirte .java file on that package explorer then how i can set the values through Employee class or EmployeeId.
plz suggest if any tutorials. i did not understand about configuration in eclipse tutorials plz.

if i create Employee emp=new Employee() —–>in this class eclipse not defined setters and gettters only empid related methods are defined.
if i create Employeeid empid=new EmployeeId()—>then i am gettig error is displaying that invalid employeeid entity.

how i can set values from which object .what is wrong in my code.this is simple but by defalut eclipse giving two classes.

anyconfiguration data is wrong?
