How to store Company simple entity to database

Create Company entity class

import javax.persistence.Column;
import javax.persistence.Id;
import java.io.Serializable;

/**
 * Company
 */
public class Company {
    /**
     * Idendificator
     */
    @Id
    @Column(name = "company_id")
    public long getId() {
        return theId;
    }

    public void setId(long aId) {
        theId = aId;
    }

    /**
     * Company name
     */
    @Column(name = "name")
    public String getName() {
        return theName;
    }

    public void setName(String aName) {
        theName = aName;
    }

    private String theName;
    private long theId;

}

Create ICompanyDao

import com.googlecode.jdbcproc.daofactory.annotation.AStoredProcedure;

import java.util.List;

/**
 * Test dao
 */
public interface ICompanyDao {

    /**
     * Creates company
     *
     * @param aCompany company to create
     */
    @AStoredProcedure(name = "create_company")
    void createCompany(Company aCompany);
}

Create mysql stored procedure

delimiter $$

create procedure create_company (
     out o_company_id int(10)
   , i_name varchar(60)
)
begin
    insert into company( name ) values (i_name);
    set o_company_id = last_insert_id();
end
$$

       theCompanyDao = aCompanyDao;
   }

   public void testCreateCompany() {
        Company company = new Company();
