package-info.java using JPA persistence.xml

Hello,

I define global metadata with hibernate annotations in visualcontrol.model.entity.package-info.java

This is my persistence.xml:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
  <persistence-unit name="VCModelPU" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>

    <class>visualcontrol.model.entity.CliFor</class>
    <class>visualcontrol.model.entity.Cliente</class>
    <class>visualcontrol.model.entity.CondicaoPagamento</class>
    <class>visualcontrol.model.entity.Cor</class>
    <class>visualcontrol.model.entity.DeclaracaoImportacao</class>
    <class>visualcontrol.model.entity.Estoque</class>
    <class>visualcontrol.model.entity.EstoqueProgramado</class>
    <class>visualcontrol.model.entity.EstoqueProjetado</class>
    <class>visualcontrol.model.entity.Familia</class>
    <class>visualcontrol.model.entity.Fornecedor</class>
    <class>visualcontrol.model.entity.Kardex</class>
    <class>visualcontrol.model.entity.LocalCobranca</class>
    <class>visualcontrol.model.entity.Loja</class>
    <class>visualcontrol.model.entity.Natureza</class>
    <class>visualcontrol.model.entity.PedidoCompra</class>
    <class>visualcontrol.model.entity.PedidoVenda</class>
    <class>visualcontrol.model.entity.PedidoVendaItem</class>
    <class>visualcontrol.model.entity.Produto</class>
    <class>visualcontrol.model.entity.Transportadora</class>
    <class>visualcontrol.model.entity.UF</class>
    <class>visualcontrol.model.entity.Usuario</class>
    <class>visualcontrol.model.entity.Vendedor</class>
    
    <properties>
      <property name="hibernate.connection.username" value=""/>
      <property name="hibernate.connection.driver_class" value="org.firebirdsql.jdbc.FBDriver"/>
      <property name="hibernate.connection.password" value=""/>
      <property name="hibernate.connection.url" value="jdbc:firebirdsql://localhost:3050/D:\DataBase\ERP_VCONTROL_LIEX.FDB"/>
      <property name="hibernate.cache.provider_class" value="org.hibernate.cache.NoCacheProvider"/>
      <property name="hibernate.dialect" value="org.hibernate.dialect.FirebirdDialect"/>
    </properties>
  </persistence-unit>
</persistence>

When I try to create the EntityManagerFactory I get this error:

Quote:

org.hibernate.MappingException: Could not determine type for: SimNaoChar, at table: LOCALCOB, for columns: [org.hibernate.mapping.Column(MOSTRAR_SITE)]

The type definition of SimNaoChar is inside package-info.java.

How do I tell to hibernate to search this package using persistence.xml? Something like <mapping package="visualcontrol.model.entity"/>?

Thanks

This is the content of package-info.java

Code:

@org.hibernate.annotations.TypeDefs({
    @org.hibernate.annotations.TypeDef(name = "SimNaoChar",
        typeClass = visualcontrol.model.BooleanCharUserType.class,
        parameters = {
            @org.hibernate.annotations.Parameter(name = "stringNull", value = "N"),
            @org.hibernate.annotations.Parameter(name = "stringTrue", value = "S"),
            @org.hibernate.annotations.Parameter(name = "stringFalse", value = "N")
    }),
    @org.hibernate.annotations.TypeDef(name = "SimNaoChar_NullSim",
        typeClass = visualcontrol.model.BooleanCharUserType.class,
        parameters = {
            @org.hibernate.annotations.Parameter(name = "stringNull", value = "S"),
            @org.hibernate.annotations.Parameter(name = "stringTrue", value = "S"),
            @org.hibernate.annotations.Parameter(name = "stringFalse", value = "N")
    })
})

package visualcontrol.model.entity;

And the mapping class:

Code:

@Entity
@Table(name = "LOCALCOB")
public class LocalCobranca implements Serializable{
//(...)
    @Column(name="MOSTRAR_SITE")
    @Type(type="SimNaoChar")
    private boolean mostrarSite;

add <class>visualcontrol.model.entity</class>

It should work

Emmanuel,

I'm testing using the property hibernate.ejb.cfgfile and in hibernate.cfg.xml I define a <mapping package see:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">

      <property name="hibernate.ejb.cfgfile" value="hibernate.cfg.xml"/>
    </properties>
  </persistence-unit>
</persistence>

hibernate.cfg.xml

Code:

<!DOCTYPE hibernate-configuration SYSTEM
  "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<!-- Arquivo para conexão do iReport ao hibernate -->  
<hibernate-configuration>
  <session-factory>
      <mapping package="visualcontrol.model.entity"/>
  </session-factory>
</hibernate-configuration>

But, after I did this I'm getting a NPE. Take a look in this post: http://forum.hibernate.org/viewtopic.php?t=984012

Thanks
