Cannot process submitted foreign keys - spring

Question

There are 3 one-to-many relationships into an entity Pta :
#Entity
#Table(name = "pta")
public class Pta {
#Id()
#SequenceGenerator(name="s_pta", sequenceName="pta.s_pta", allocationSize=1)
#GeneratedValue(strategy=GenerationType.SEQUENCE, generator="s_pta")
#Column(name="pta_code")
private Integer code;
#Column(name="pta_intitule")
private String lib;
#ManyToOne
#JoinColumn(name = "obj_code")
private Objectif objectif;
#ManyToOne
#JoinColumn(name = "struct_code")
private Structure structure;
#ManyToOne
#JoinColumn(name = "exer_code")
private Exer exercice;
public Pta() {
super();
}
public Pta(Integer code) {
super();
this.code = code;
}
// getters and setters
}
#Entity
#Table(name = "objectif")
public class Objectif {
#Id
#SequenceGenerator(name="s_objectif", sequenceName="pta.s_objectif", allocationSize=1)
#GeneratedValue(strategy=GenerationType.SEQUENCE, generator="s_objectif")
#Column(name = "obj_code")
private int code;
#Column(name="obj_intitule")
private String lib;
#ManyToOne
#JoinColumn(name = "prog_code")
private Programme programme;
#ManyToOne
#JoinColumn(name = "nat_obj_code")
private NatureObjectif nature_objectif;
public Objectif() {
super();
}
public Objectif(int code) {
super();
this.code = code;
}
public Objectif(int code, String lib) {
super();
this.code = code;
this.lib = lib;
}
// getters and setters
}
#Entity
#Table(name = "structure")
public class Structure {
#Id()
#Column(name="struct_code")
private String code;
#Column(name="struct_sigle")
private String sigle;
#Column(name="struct_lib")
private String lib;
public Structure() {
super();
}
public Structure(String code) {
super();
this.code = code;
}
// getters and setters
}
#Entity
#Table(name = "exercice")
public class Exer {
#Id()
#Column(name="exer_code")
private String exerCode;
#Column(name="exer_lib")
private String exerLibelle;
public Exer(){
super();
}
public Exer(String exer_code) {
super();
this.exerCode = exer_code;
}
// getters and setters
}
I want to insert a record into the Pta.
controller for page jsp :
modelView.addObject("exercices",exerDao.list());
modelView.addObject("structures",structureDao.list());
HashMap<String, String> criteres = new HashMap<String, String>();
criteres.put("nat_obj_code", "DdP");
modelView.addObject("docs_perf", objectifDao.lireParCritere(criteres));
criteres.clear();
criteres.put("nat_obj_code", "ODD");
modelView.addObject("odds", objectifDao.lireParCritere(criteres));
criteres.clear();
criteres.put("nat_obj_code", "PRO");
modelView.addObject("produits", objectifDao.lireParCritere(criteres));
modelView.addObject("action", request.getContextPath().concat("/elaboration/savePtaEtDetails"));
modelView.addObject("pta_formulaire", new Pta());
return modelView;

In the controller target :
#RequestMapping(value = "/savePtaEtDetails", method = RequestMethod.POST)
public ModelAndView savePtaEtDetails(#ModelAttribute("pta_formulaire") Pta pta, #RequestParam String exercice, #RequestParam int objectif,
#RequestParam String structure) {
System.out.println("eeeeeeeeeeeeeeee");
return new ModelAndView("redirect:/accueil");
}
At runtime when submitting the form then I got the error The request sent by the client was syntactically incorrect. So what is wrong ?

Answer 1

I found it :) The solution was to not set the attribute in the constructor of the "master" entities :
public Exer(String exer_code) {
super();
}
public Structure(String code) {
super();
}
public Objectif(String code) {
super();
}
