after debuging, the problem is here :

{
depbool = false;
}
if(depbool){

exactely here :
dbD.create(departement);

this is what i want to do (UML): imgur
this is the link of my last error for more infos : Link
can some one help ?
回答1:
Your question is a real mess... but if you read the exception:
Provided id of the wrong type. Expected: class java.lang.Integer, got class java.lang.String
Anf after you take a look to your Departement class, it has only 2 fields and one set (according to the hibernate mapping):
int id;
String nomDepartament;
Set employees;
That only can mean, youre passing the nomDepartament field instead of id somewhere in your code...
But as far as you are not providing, the Departement class or DepartementImplMetier.create() method, that is the one causing the exception I cannot say more...
So... start here focus your problems, and provide only important parts of the code.
