I have 2 class are Person and Book. a book will have an author. Book will have relationship one - one with Person and Person will have relationship one - many with Book. 2 class as below :

Person.java

package quickstart.model;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.OneToMany;

import org.hibernate.mapping.Set;
import org.hibernate.search.annotations.*;

@Entity
@Indexed(index="indexes/Person")
public class Person {

@Id
@GeneratedValue
@DocumentId
private Integer id;

@Field(index=Index.TOKENIZED, store=Store.NO)
private String firstName;

@Field(index=Index.TOKENIZED, store=Store.NO)
private String lastName;

@ContainedIn
@OneToMany(mappedBy = "Person")
private Set<Book> books;


public String getFirstName() {
return firstName;
}

public void setFirstName(String firstName) {
this.firstName = firstName;
}

public String getLastName() {
return lastName;
}

public void setLastName(String lastName) {
this.lastName = lastName;
}

public Integer getId() {
return id;
}

public void setId(Integer id) {
this.id = id;
}
}

and Book.java

package quickstart.model;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.OneToOne;
import javax.persistence.CascadeType;

import org.hibernate.search.annotations.*;
import quickstart.model.Person;

@Entity
@Indexed(index="indexes/Book")
public class Book {

@Id
@GeneratedValue
@DocumentId
private Integer id;

@Field(index=Index.TOKENIZED, store=Store.NO)
private String name;

@OneToOne( cascade = { CascadeType.PERSIST, CascadeType.REMOVE } )
@IndexedEmbedded
private Person author;

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public Person getAuthor() {
return author;
}

public void setAuthor(Person author) {
this.author = author;
}

public Integer getId() {
return id;
}

public void setId(Integer id) {
this.id = id;
}
}

but it throw 3 errors as below:
-MappedBy specified for books does not exist on the target entity class
-Target null.class is not an entity
-The type Set is not generic; it cannot be parameterized with arguments <Book>

can you show me the problem????
thx

at least it should be mappedBy="author" ie the name of the property on the other side.

I replace mappedBy = "person" with mappedBy = "author" but the error don't change.it still have that 3 error.
