First post to stackoverflow, so please excuse if I did not post correctly. I posted a follow-up question with code on an old thread Mapping value in junction table to Entity as I am not able to get the recommended solution to function properly. I am using OpenXava and receive error "Impossible to execute Save action: org.hibernate.PropertyAccessException: could not set a field value by reflection setter of org.openxava.invoicing.model.CourseAssignmentId.course". Any help is appreciated. My code:
User Class:
@Entity @Table(name="users") public class User { @Id @Column(name="pk1") private Long id; public Long getid() { return id; } public void setid(Long id) { this.id = id; } @Column(name="user_id") private String userID; public String getuserID(){ return userID; } public void setuserID(String userID) { this.userID = userID; } @OneToMany(mappedBy="user") private Collection<CourseAssignment> courseAssignments; public Collection<CourseAssignment> getcourseAssignments() { return courseAssignments; } public void setcourseAssignments(Collection<CourseAssignment> courseAssignments) { this.courseAssignments = courseAssignments; } } Course Class:
@Entity @Table(name="courses") public class Course { @Id @Column(name="pk1") private Long id; public Long getid() { return id; } public void setid(Long id) { this.id = id; } @Column(name="course_name") private String name; public String getname() { return name; } public void setname(String name) { this.name = name; } @OneToMany(mappedBy = "course") private Collection<CourseAssignment> courseAssignments; public Collection<CourseAssignment> getcourseAssignments() { return courseAssignments; } public void setcourseAssignments(Collection<CourseAssignment> courseAssignments) { this.courseAssignments = courseAssignments; } } CourseAssignment Class:
@Entity @Table(name="course_users") @IdClass(CourseAssignmentId.class) public class CourseAssignment { @Id @ManyToOne @JoinColumn(name="user_pk1") private User user; public User getuser() { return user; } public void setuser(User user) { this.user = user; } @Id @ManyToOne @JoinColumn(name="crsmain_pk1") private Course course; public Course getcourse() { return course; } public void setcourse(Course course) { this.course = course; } @Column(name="role") private String role; public String getrole() { return role; } public void setrole(String role) { this.role = role; } } CourseAssignmentId Class:
@Embeddable public class CourseAssignmentId implements java.io.Serializable { private static final long serialVersionUID = 1L; @Column(name="user_pk1") private Long user; public Long getuser() { return user; } public void setuser(Long user) { this.user = user; } @Column(name="crsmain_pk1") private Long course; public Long getcourse() { return course; } public void setcourse(Long course) { this.course = course; } }
