Here is my code for both entities:
@Entity(name = "StudentUni")
public class Student implements Serializable {
private int id;
private String name;
private Collection courses = new ArrayList();
public Student(){
id = (int) System.nanoTime();
}
@Id
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@ManyToMany
public Collection getCourses() {
return courses;
}
public void setCourses(Collection courses) {
this.courses = courses;
}
}
@Entity(name = "CourseUni")
public class Course implements Serializable {
private int id;
private String courseName;
private Collection students = new ArrayList();
public Course(){
id = (int) System.nanoTime();
}
@Id
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getCourseName() {
return courseName;
}
public void setCourseName(String courseName) {
this.courseName = courseName;
}
@ManyToMany(mappedBy = "courses")
public Collection getStudents() {
return students;
}
public void setStudents(Collection students) {
this.students = students;
}
}
Please help!!
