Não grava livro - mensagem que a tabela não foi criada

Bom dia pessoal, criei minha datasource, e ao entrar no painel administrativo do wildfly, entro em datasources e ta tudo legalzinho. Testei a conexão e funcionou legal como pode ser visto nesse print link : http://prntscr.com/g0istl

Ao tentar cadastrar o livro, no debug, todas as informações digitadas vem normalmente, porém ele da a mensagem de erro que a tabela Livros não pode ser encontrada:

Reparei que ao subir o projeto, ele não criou a tabela como aconteceu na aula. O que pode ser?

segue o código da minha classe

package br.com.alura.casadocodigo.models;

import javax.persistence.*;
import java.math.BigDecimal;

@Entity
public class Livro {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer id;
    private String titulo;
    @Lob
    private String descricao;
    private int numeroPaginas;
    private BigDecimal preco;

    public String getTitulo() {
        return titulo;
    }

    public void setTitulo(String titulo) {
        this.titulo = titulo;
    }

    @Override
    public String toString() {
        return "Livro{" +
                "titulo='" + titulo + '\'' +
                ", descricao='" + descricao + '\'' +
                ", numeroPaginas=" + numeroPaginas +
                ", preco=" + preco +
                '}';
    }

    public String getDescricao() {
        return descricao;
    }

    public void setDescricao(String descricao) {
        this.descricao = descricao;
    }

    public int getNumeroPaginas() {
        return numeroPaginas;
    }

    public void setNumeroPaginas(int numeroPaginas) {
        this.numeroPaginas = numeroPaginas;
    }

    public BigDecimal getPreco() {
        return preco;
    }

    public void setPreco(BigDecimal preco) {
        this.preco = preco;
    }
}
