Answer 1

I solved my problem. Here is what I did in order to make it work: Firstly I changed dependency to jackson2

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
    <version>2.4.3</version>
</dependency>

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>
    <version>2.4.3</version>
</dependency>

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.4.3</version>
</dependency>

Then I annotated my Book class with @JsonProperty and @JsonIgnore. Here is my updated Book class

 @Entity
    @Table(name="Book")
    @Indexed
    public class Book {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "bookId")
    @JsonIgnore
    private Long id;
    @Column(nullable = false)
    @Field(index = Index.YES, analyze=Analyze.YES, store=Store.NO)
    @JsonProperty("title")
    private String title;
    @Column(nullable = false, unique = true)
    @JsonProperty("ISBN")
    private String ISBN;
    @Column(nullable = false)
    @Field(index = Index.YES, analyze=Analyze.YES, store=Store.NO)
    @JsonProperty("author")
    private String author;
    @JsonProperty("publisher")
    private String publisher;
    @Column(length = 1000)
    @JsonProperty("description")
    private String description;
    @JsonProperty("publicationYear")
    private int publicationYear;
    @JsonProperty("pages")
    private int pages;
    @Enumerated(EnumType.STRING)
    @Column(nullable = false)
    @JsonIgnore
    private BookStatus bookStatus;
    @ManyToMany(mappedBy = "booksWant", cascade = CascadeType.ALL)
    @JsonIgnore
    private List<User> user = new ArrayList<User>(0);
    @OneToMany(mappedBy = "book", cascade = CascadeType.ALL)
    @JsonIgnore
    private List<UserBook> bookList = new ArrayList<UserBook>(0);

    public Book(String title, String ISBN, String author, String publisher, String description,
                int publicationYear, int pages, BookStatus bookStatus) {
        this.title = title;
        this.ISBN = ISBN;
        this.author = author;
        this.publisher = publisher;
        this.description = description;
        this.publicationYear = publicationYear;
        this.pages = pages;
        this.bookStatus = bookStatus;
    }
     getters and setters

}

Answer 2

Remove "'contentType: 'application/json'," from the ajax call
