Hello Please Help me quickly
i`ve written a many-to-one mapping it create correctly oracle tables but when i`m going to set courseid {thestudent.setCourseid(1L);} it ocures error see below :
Class Student :
public class Student {
private Long id;
private String name;
private String family;
private Long courseid;
public Student() {
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getFamily() {
return family;
}
public void setFamily(String family) {
this.family = family;
}
public Long getCourseid() {
return courseid;
}
public void setCourseid(Long courseid) {
this.courseid = courseid;
}
}
