<?xml version="1.0" encoding="UTF-8"?>


<persistence-unit name="site" transaction-type="RESOURCE_LOCAL">

<provider>org.hibernate.ejb.HibernatePersistence</provider>

<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect"/>


</properties>

</persistence-unit>

o maven está assim

a classe assim:

package br.com.pousadadobicao.modelo;

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

@Entity
public class Preco{

@Id
@GeneratedValue
private int idPreco;
private String mes;


public int getIdPreco() {
	return idPreco;
}
public void setIdPreco(int idPreco) {
	this.idPreco = idPreco;
}
public String getMes() {
	return mes;
}
public void setMes(String mes) {
	this.mes = mes;
}

}

e qndo levanto o tomcat não aparece as classes no meu BD
