Hibernate Mapping Issue Tomcat8

Question

I'm having problem with mapping in hibernate and tomcat 8.

When I deploy the application(through manager/html or creating a new folder and putting the whole project) there is not problem but if I try to put the classes into WEB-INF of another existing application and run it, log says:

org.hibernate.hql.internal.ast.QuerySyntaxException: Telefonos is not mapped [FROM Telefonos where canal = :canal and (fechaTomado is null or (fechaTomado + 90) >= getdate())]

Caused by: org.hibernate.hql.internal.ast.QuerySyntaxException: Telefonos is not mapped

Teléfonos entity

package operaciones.telefonoscvts.dao;

import java.io.Serializable;
import javax.persistence.*;

@Entity
@Table(name = "telefonos_cvts")
public class Telefonos implements Serializable {

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "id")
private int id;

@Column(name = "telefono")
private String telefono;

@Column(name = "modalidad")
private String modalidad;

@Column(name = "canal")
private String canal;

@Column(name = "fechaCarga")
private String fechaCarga;

@Column(name = "fechaTomado")
private String fechaTomado;

public Telefonos() {
}

//get and set methods

I tried many ways to make work it, the packages are fine, hibernate.cfg.xml it's read, I don't know why the app it's losing its mappings. Anny help is appreciated.

Hibernate: 4.3

Thanks!!

Answer 1

I see your mapping is correct. The most probable solution is to check whether you have included the entity to Hibernate configuration:

@Bean
public LocalSessionFactoryBean sessionFactory() {
    LocalSessionFactoryBean lsfb = new LocalSessionFactoryBean();
    lsfb.setDataSource(this.dataSource());
    lsfb.setPackagesToScan(new String[] { 
        "operaciones.telefonoscvts.dao"
    });
    lsfb.setHibernateProperties(this.hibernateProperties());
    return sessionFactory;
}

The same effect you can achieve using xml based configuration. However I find annotations better in this case.

<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" >
    <property name="dataSource" ref="dataSource"/>
    <property name="packagesToScan">
        <list>
            <value>operaciones.telefonoscvts.dao</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">${hibernate.dialect}</prop>
            <prop key="hibernate.show_sql">${hibernate.show_sql:false}</prop>
            <prop key="hibernate.format_sql">${hibernate.format_sql:false}</prop>
        </props>
    </property>       
</bean>

Moreover, I recommend you to more the file Telefonos.java to the package operaciones.telefonoscvts.entity (or model ) separately from the classes responsible to communication with database.
