Why CriteriaQuery is putting dot in hibernate string?

I have a problem with my multiselect. I'm using it as an Specification with multiple joins. I don't know why hibernate decides to put a dot in the query. the error is shown below in the query. this is the constructor I'm using
public HelperOutput(Long id,
String personName,
Long helperTypeId,
String helperTypeTitle,
String agencyTitle,
String regionalOfficeTitle,
String basketPartTitle,
YesNo allowedToOperate,
YesNo hasFlatTirePack,
Long fleetRescueId,
Long cityId,
String cityName,
Long skillLevel,
String helperRankTitle,
Long personId,
Long helperRate,
String personelId,
Long regionalOfficeId,
Long basketPartId,
String mobile,
String fleetName,
ExpertType expertType,
Long maxConcurrentWork,
Set<Long> dutyCityIds
) {
this.id = id;
this.helperTypeId = helperTypeId;
this.helperTypeTitle = helperTypeTitle;
this.agencyTitle = agencyTitle;
this.regionalOfficeId = regionalOfficeId;
this.regionalOfficeTitle = regionalOfficeTitle;
this.basketPartTitle = basketPartTitle;
this.fleetRescueId = fleetRescueId;
this.cityId = cityId;
this.helperRankTitle = helperRankTitle;
this.personId = personId;
this.basketPartId = basketPartId;
this.mobile = mobile;
this.fleetName = fleetName;
this.cityName = cityName;
this.personName = personName;
this.allowedToOperate = allowedToOperate;
this.hasFlatTirePack = hasFlatTirePack;
this.skillLevel = skillLevel;
this.helperRate = helperRate;
this.personelId = personelId;
this.expertType = expertType;
this.maxConcurrentWork = maxConcurrentWork;
this.dutyCityIds = dutyCityIds;
}
this is the multiselect which is similar to the constructor.
cq.multiselect(root.get(Helper_.ID),
personName,
helperHelperTypeJoin.get(HelperType_.ID),
helperHelperTypeJoin.get(HelperType_.TITLE),
helperAgencyJoin.get(Agency_.TITLE),
helperRegionalOfficeJoin.get(RegionalOffice_.TITLE)
, helperBasketPartJoin.get(Basket_.TITLE),
root.get(Helper_.ALLOWED_TO_OPERATE),
root.get(Helper_.HAS_FLAT_TIRE_PACK),
fleetRescueJoin.get(HelperFleet_.ID),
helperCityJoin.get(City_.ID) ,
helperCityJoin.get(City_.NAME),
root.get(Helper_.SKILL_LEVEL),
helperRankJoin.get(HelperRank_.NAME),
helperPersonJoin.get(Person_.ID),
root.get(Helper_.helperRate),
root.get(Helper_.personelId),
helperRegionalOfficeJoin.get(RegionalOffice_.ID),
helperBasketPartJoin.get(Basket_.ID),
helperPersonJoin.get(Person_.MOBILE),
HelperFleetJoin.get(Fleet_.NAME),
root.get(Helper_.EXPERT_TYPE),
root.get(Helper_.MAX_CONCURRENT_WORK),
root.get(Helper_.DUTY_CITIES)
);
this is the hibernate query which I don't know why it has a dot.

I answered it in a comment in Helper entity. the answer is you shouldn't make a mistake in mappedBy attribute in #OneToMany annotation. so I changed dutyCityId to helper now it's working.
before it was joining with another condition helper.ID = helperDutyCity.dutyCityId which was wrong now it joins with this condition helper.ID = helperDutyCity.helperId which is correct.

hibernate session save method not working?

I 'm new in spring and hibernate. i have a sample project that not work properly. when i try to save new order from user, i get no error or exceprion, but record not inserted into database.
here my code

}
when i try to add new order i get no exception. why my service not work?
i have another controller in my project, that manage users. in that controller and dao implementation add and remove user working properly.
i think i have logic error in my code for one to many and many to many. please help me to overcome this fail.

Embeddable/ ManyToOne/ OneToMany not working

I' m quite knew to Java and currently I am working on a ChatProgramm.
So I want to create a table Messages embedded with the ID (USERNUMBER) of my table Contacts using Injections.
Here' s the class of my Message:
#Embeddable
#Entity(name = "MESSAGE")
public class Message implements Serializable {
#ManyToOne
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "INCOME_MESSANGE", nullable = false)
private String incomingMessage;
#EmbeddedId
#JoinColumn(name = "USERNUMBER", nullable = false)
private Contact contact;
ChatApplicationRemote chatApplicationRemote;
public Message(String ip, String msg) throws IOException {
incomingMessage = msg;
contact = chatApplicationRemote.getcontactByIP(ip.toString());
}
public Message(){
}
public String getIncomingMessage() {
return incomingMessage;
}
public Contact getContact() {
return contact;
}
And here my contacts:
#Entity(name = "CONTACTS")
#Embeddable
public class Contact implements Serializable {
/**
*
*/
private static final long serialVersionUID = -6855140755056337926L;
#Column(name = "NAME", nullable = false)
private String name;
#Column(name = "PRENAME", nullable = false)
private String vorname;
#Column(name = "IP", nullable = false)
private String ip;
#Column(name = "PORT", nullable = false)
private Integer port;
#Id
#OneToMany(mappedBy = "Message.incomingMessage")
#Column(name = "USERNUMBER", nullable = false)
private String usernumber;
public Contact(String usernumber, String name, String vorname, String ip, String port) {
super();
this.usernumber = usernumber;
this.name = name;
this.vorname = vorname;
this.ip = ip;
this.port = Integer.parseInt(port);
}
public Contact(){
}
public String getUsernumber() {
return usernumber;
}
//......
So in my Message, I get two errors:
#ManyToOne throws : Target entity "java.lang.String" is not an Entity
#EmbeddedID throws : de.nts.data.Contact is not mapped as an embeddable
So I googled for a while.. and found something abouta orm.xml which I hadn't have. And even if I create one, #EmbeddedID throws:Embedded ID class should include method definitions for equals() and hashcode() and the orm.xml Attribute "usernumber" has invalid mapping type in this context.
Can anyone please help?

Try
#Entity
public class Message implements Serializable {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private Long id;
#Column(name = "INCOME_MESSANGE", nullable = false)
private String incomingMessage;
#ManyToOne
#JoinColumn(name = "USERNUMBER", nullable = false)
private Contact contact;
#Transient
ChatApplicationRemote chatApplicationRemote;
..
}
#Entity
public class Contact implements Serializable {
private static final long serialVersionUID = -6855140755056337926L;
#Column(name = "NAME", nullable = false)
private String name;
#Column(name = "PRENAME", nullable = false)
private String vorname;
#Column(name = "IP", nullable = false)
private String ip;
#Column(name = "PORT", nullable = false)
private Integer port;
#Id
#Column(name = "USERNUMBER", nullable = false)
private String usernumber;
#OneToMany(mappedBy = "incomingMessage")
private LIst<Message> messages;
..
}
maybe as a starting point, but as JB Nizet suggested, start with some simple JPA/Java demos to get the basics first and build up. Your example has many more errors then just what the exception was showing, none of which are solved by just throwing in an ORM.xml.

JPA incompatible mapping in ManyToMany relationship. Cardinality does not correspond with the cardinality of its backpointer

Any help would be valuable, thank you

Remove #Basic from all of your association mappings. #Basic is intended to be used with primitive fields. From http://en.wikibooks.org/wiki/Java_Persistence/Basic_Attributes
A basic attribute is one where the attribute class is a simple type such as String, Number, Date or a primitive. A basic attribute's value can map directly to the column value in the database.

OneToMany between 2 classes with Hibernate

I'm trying to get the hang of Hibernate.
After getting my project to compile, I've started to convert my classes to be "Hibernate-enabled"
Currently, I'm having 2 classes
1) Person (id, name, firstname, ...)
2) Task (Id, name, description, idOwner)
I would like to have a OneToMany relationship between Person(id) and Task (idOwner)
So when the users gets the List from the Person class, they would get all the tasks linked to that.
After some trying and failing, here's my current code:
Person.java
#Entity
#Table(name = "people", uniqueConstraints = {
#UniqueConstraint(columnNames = "PERSON_ID")
})
public class Person implements Serializable {
private int id;
private String firstName;
private String name;
private String function;
private String email;
private String password;
private RoleEnum role;
private List<Task> lstTasks;
public Person(String firstName, String name, String function) {
this.firstName = firstName;
this.name = name;
this.function = function;
this.email = "";
this.password = "";
this.setRole(RoleEnum.User);
}
// <editor-fold defaultstate="collapsed" desc="Getters">
#Id
#GeneratedValue(strategy = IDENTITY)
#Column(name = "PERSON_ID", unique = true, nullable = false)
public int getId() {
return id;
}
#Column(name = "PERSON_FIRSTNAME", unique = false, nullable = false, length = 30)
public String getFirstName() {
return firstName;
}
#Column(name = "PERSON_NAME", unique = false, nullable = false, length = 30)
public String getName() {
return name;
}
#Column(name = "PERSON_FUNCTION", unique = false, nullable = false, length = 30)
public String getFunction() {
return function;
}
#Column(name = "PERSON_EMAIL", unique = false, nullable = false, length = 30)
public String getEmail() {
return email;
}
#Column(name = "PERSON_PASSWORD", unique = false, nullable = false, length = 30)
public String getPassword() {
return password;
}
#Column(name = "PERSON_ROLE", unique = false, nullable = false, length = 30)
public RoleEnum getRole() {
return role;
}
#OneToMany(fetch = FetchType.LAZY, mappedBy = "idOwner")
public List<Task> getLstTasks() {
return lstTasks;
}
//Setters
}
Task.java
#Entity
#Table(name="tasks", uniqueConstraints =
#UniqueConstraint(columnNames = "TASK_ID"))
public class Task implements Serializable {
private int id;
private String name;
private String description;
private int idOwner;
public Task(int id, String name, int idOwner) {
this.id = id;
this.name = name;
this.idOwner = idOwner;
}
// <editor-fold defaultstate="collapsed" desc="Getters">
#Id
#GeneratedValue(strategy = IDENTITY)
#Column(name = "TASK_ID", unique = true, nullable = false)
public int getId() {
return id;
}
#Column(name = "TASK_NAME")
public String getName() {
return name;
}
#Column(name = "TASK_DESCRIPTION")
public String getDescription() {
return description;
}
#Column(name = "TASK_ID_OWNER")
public int getIdOwner() {
return idOwner;
}
// </editor-fold>
//Setters
}
Can somebody tell/show/explain me what I have to do exactly, to make this work?

Currently your mapping should linking ownerId instead of Task class.
Change your Task class to this
private Person person;
#ManyToOne
#JoinColumn(name = "TASK_ID_OWNER")
public Person getPerson() {
return person;
}

In your Person entity you have declared one-to-many relationship with Task entity like this:
#OneToMany(fetch = FetchType.LAZY, mappedBy = "idOwner")
public List<Task> getLstTasks() {
return lstTasks;
}
Here you have given idOwner to mappedBy attribute, it means you are telling hibernate that there is property in Task class called idOwner which is of type Person.
So you have to modify your Tasks class like this (Changing the variable type from int to Person):
private Person idOwner;
#ManyToOne
#JoinColumn(name = "TASK_ID_OWNER")
public Person getIdOwner() {
return idOwner;
}
public void setIdOwner(Person idOwner) {
this.idOwner=idOwner;
}
If you remove the #JoinColumn annotation then hibernate will create a Join table for your relationship, else it will just create a foreign key in Task table with foreign key column name as TASK_ID_OWNER.
