Spring Hibernate JPA HSQL Table not found in statement - spring

Question

I'm training Spring persistence with LocalContainerEntityManagerFactoryBean and getting error:
Caused by: java.sql.SQLException: Table not found in statement [insert into PERSON (ID, email, name) values (null, ?, ?)]
Don't really know what I did wrong
My Main class (for test only)
package com.me.test;
import com.me.model.Person;
import com.me.service.PersonService;
import java.util.List;
import java.util.logging.Logger;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Main {
/**
*
*/
public static final Logger log = Logger.getLogger(Main.class.getName());
public static void main(String[] args) {
log.info("************** BEGINNING PROGRAM **************");
ApplicationContext context = new ClassPathXmlApplicationContext("WEB-INF/spring-config.xml");
PersonService personService = (PersonService) context.getBean("personService");
Person person = new Person();
person.setName("name");
person.setEmail("name#name.com");
personService.addPerson(person);
log.info("Person : " + person + " added successfully");
List<Person> persons = personService.fetchAllPersons();
log.info("The list of all persons = " + persons);
log.info("************** ENDING PROGRAM *****************");
}
}
My application context:

What's wrong here guys?
edit:
adding person class:
package com.me.model;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name = "PERSON")
public class Person implements Serializable{
private Integer id;
private String name;
private String email;
#Id
#GeneratedValue
#Column(name = "ID")
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
#Override
public String toString() {
return "Person [id=" + id + ", name=" + name + ", email=" + email + "]";
}
}
and persistence.xml
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
version="1.0">
<persistence-unit name="personPersistenceUnit" transaction-type="RESOURCE_LOCAL" >
<class>com.me.model.Person</class>
</persistence-unit>
</persistence>

Answer 1

The problem is that you have not told Hibernate anywhere that it needs to create the tables when it loads.
An easy way to do that would be to add
<properties>
<property name="hibernate.hbm2ddl.auto" value="create-drop"/>
</properties>
inside persistence.xml after <class>
