RussianQuestion
I'm using Glassfish 4 and JPA 2.1 ans Netbeans 7.
In order to generate the table I have these beans :
@Entity
public class Myuser implements Serializable{
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long myuserId;
@Column(name = "firstname")
private String firstName;
@Column(name = "lastname")
private String lastName;
@Column(name = "mail")
private String mail;
@Column(name = "password")
private String password;
@OneToMany @JoinColumn(name = "user", insertable=false, updatable=false)
private Collection<Course> courses;
//...
}
@Entity
public class Course implements Serializable{
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long courseId;
@Column(name = "coursename")
private String courseName;
@Column(name = "duration")
private int duration;
@Column(name = "description")
private String description;
@ManyToOne @JoinColumn(name="myuserId", insertable=false, updatable = false)
private Myuser user;
@OneToMany @JoinColumn(name ="course", insertable=false, updatable = false)
private Collection<Mymodule> modules;
//...
}
And I got this server Database log message :
Avertissement: Local Exception Stack:

Solution
It looks like the the column "user" is the problem. "USER" is a reserved word in Derby and as such should probably not be used as a column name. If you MUST use it as a column name make sure to enclose it in quotes as shown in this question.
OTHER TIPS
I guess 'user' is a database keyword and cannot be used! You must change your mapping to use a different column name.
