Context: Jboss5.1, MySql 5.0

I've tried a lot of possibilities .. a simple @GeneratedValue or other solution specifing explicitly the sequence generator, but also have the same problem... There is the stack trace

Actual entity code for the interesting part:

@Entity
public class Lavoro implements Serializable {
    private static final long serialVersionUID = 1L;


    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private long id;

    private String nome;

    private String sede;

    private String stato;

Code in which I encounter the error:

Lavoro lavoro = new Lavoro();
        lavoro.setNome(formLavoro.getNome());
        lavoro.setSede(formLavoro.getSede());
        lavoro.setStato("PENDENTE");
        lavoro.setPersona(p);
        lavoro.setAbilitas(listaAbilita);
        lavoro.setRichiestapartecipazionelavoros(new ArrayList<Richiestapartecipazionelavoro>());
        lavoro.setPersonas(new ArrayList<Persona>());
        lavoro.setFeedbacks(new ArrayList<Feedback>());
        System.out.println("Prima del persist");
        manager.persist(lavoro);

NB:manager is the entity manager.

MySQL for the ID field is set to NOT_NULL and AUTO_INCREMENT.

Maybe you should check the mappings. There can be some problem with ID used in other table as a foreign key?

Shirline answered 24/1, 2013 at 22:41 Comment(1)
checked again! Resolved adding other individual 'id' to all entity linked... Not using anymore a foreign key. – Megrims

Are you using a sequence on MySQL? MySQL supports value generation usinf a AUTO_INCREMENT field on your database. You dont need to specify a SequenceGenerator.

Like this:

@Id
@GeneratedValue(strategy = GenerationType.AUTO)

MySQL field definition:

YOUR_FIELD BIGINT(20) NOT NULL AUTO_INCREMENT

Trying... Not working... i've putted '@Id @GeneratedValue(strategy = GenerationType.AUTO)' and I've setted AutoIncrement for the field in mysql... but the problem is still here – Megrims
Thanks, it's work. but can I insert random id in a database? because I don't want auto increment an id. – Rimarimas

make sure that you are not using setter for your primary key in model class. package com.example.models;

@Entity
public class BlogDetails {
@Id
@GeneratedValue
@Column(name="B_Id",nullable=false)
private int b_Id;
@Column(name="EmailId")
private String emailId;
@Column(name="Title")
private String title;
@Column(name="BriefDetail")
private String briefDetail;
@Column(name="Detail")
private String detail;

public BlogDetails() {
}

public BlogDetails(String EmailId, String Title, String BriefDetail, String      

Detail) {
this.emailId=EmailId;
this.title=Title;
this.briefDetail=BriefDetail;
this.detail=Detail;
}

public int getB_Id() {
return b_Id;
}

public String getEmailId() {
return emailId;
}

public void setEmailId(String emailId) {
this.emailId = emailId;
}

public String getTitle() {
return title;
}

public void setTitle(String title) {
this.title = title;
}

public String getBriefDetail() {
return briefDetail;
}

public void setBriefDetail(String briefDetail) {
this.briefDetail = briefDetail;
}

public String getDetail() {
return detail;
}

public void setDetail(String detail) {
this.detail = detail;
}


}

This throws an error: org.hibernate.PropertyNotFoundException: Could not find a setter for property id in class – Drawshave

Try this:

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
