The jar deployed without any problems. The EJBPU is defined in persistrence.xml:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
  <persistence-unit name="EJBPU" transaction-type="JTA">
    <jta-data-source>jdbc/funnyJNDI</jta-data-source>
    <properties/>
  </persistence-unit>
</persistence>

The line 27 is this one:

lib.setIsbn(isbn);

in the method addBook.

The entity bean looks as follows:

/*

 * and open the template in the editor.
 */

package entity;

import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.NamedQueries;
import javax.persistence.NamedQuery;
import javax.persistence.Table;

/**

 * @author Nupek
 */
@Entity
@Table(name = "book")
@NamedQueries({_at_NamedQuery(name = "Book.findByIsbn", query = "SELECT b FROM Book b WHERE b.isbn = :isbn"), @NamedQuery(name = "Book.findByAuthor", query = "SELECT b FROM Book b WHERE b.author = :author"), @NamedQuery(name = "Book.findByTitle", query = "SELECT b FROM Book b WHERE b.title = :title")})
public class Book implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @Column(name = "isbn", nullable = false)
    private String isbn;
    @Column(name = "author")
    private String author;
    @Column(name = "title")
    private String title;

    public Book() {
    }

    public Book(String isbn) {
        this.isbn = isbn;
    }

    public String getIsbn() {
        return isbn;
    }

    public void setIsbn(String isbn) {
        this.isbn = isbn;
    }

    public String getAuthor() {
        return author;
    }

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

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    @Override
    public int hashCode() {
        int hash = 0;
        hash += (isbn != null ? isbn.hashCode() : 0);
        return hash;
    }

    @Override
    public boolean equals(Object object) {
        // TODO: Warning - this method won't work in the case the id fields are not set
        if (!(object instanceof Book)) {
            return false;
        }
        Book other = (Book) object;
        if ((this.isbn == null && other.isbn != null) || (this.isbn != null && !this.isbn.equals(other.isbn))) {
            return false;
        }
        return true;
    }

    @Override
    public String toString() {
        return "entity.Book[isbn=" + isbn + "]";
    }
