Hello
I have a problem with my configuration of Annotations.

with Hibernate 3.6.1, Im taying to map a Mysql 5.5 database, in a Liferay 6 Portlet
I can do de mapping with HBM files and everithing works fine, but when I try to doit with annotations I get the error:

Code:

Initial SessionFactory creation failed.org.hibernate.AnnotationException: @OneToOne or @ManyToOne on com.timestamp.database.datatypes.Freguesia.concelho references an unknown entity: com.timestamp.database.datatypes.Concelho
08:15,625 ERROR [PortletRequestDispatcherImpl:107] org.apache.jasper.JasperException: An exception occurred processing JSP page /view.jsp at line 19

   List<Distrito> studentResult=null;
   List<Categoria> categResult=null;
   try{
      Session sessions = HibernateUtil2.getSession();
      sessions.beginTransaction();
      
    studentResult = sessions.createQuery("from Distrito").list();

The bean code is the following:

Code:

package com.timestamp.database.datatypes;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;

@Entity
@Table(name = "CIOFE_FREGUESIA")
public class Freguesia
{
   @Id
   @Column(name = "ID")
   @GeneratedValue(strategy = GenerationType.IDENTITY)
   public Integer   id;
   @Column(name = "CODE", unique = true, length = 10)
   public String   code;
   @Column(name = "NAME", length = 100)
   public String   name;
   @ManyToOne
   @JoinColumn(name = "ID_CONCELHO")
   public Concelho   concelho;

   public Integer getId()
   {
      return id;
   }

   public void setId(Integer id)
   {
      this.id = id;
   }

   public String getCode()
   {
      return code;
   }

   public void setCode(String code)
   {
      this.code = code;
   }

   public String getName()
   {
      return name;
   }

   public void setName(String name)
   {
      this.name = name;
   }

   public Concelho getConcelho()
   {
      return concelho;
   }

   public void setConcelho(Concelho concelho)
   {
      this.concelho = concelho;
   }
}

Code:

package com.timestamp.database.datatypes;

import java.util.Vector;

import javax.persistence.Column;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;

import org.hibernate.annotations.Entity;

@Entity
@Table(name = "CIOFE_CONCELHO")
public class Concelho
{
   @Id
   @Column(name = "ID")
   @GeneratedValue(strategy = GenerationType.IDENTITY)
   public Integer   id;
   @Column(name = "CODE", length = 10)
   public String   code;
   @Column(name = "NAME", length = 100)
   public String   name;
   @ManyToOne
   @JoinColumn(name = "ID_DISTRITO")
   public Distrito   myDistrito;

   public Integer getId()
   {
      return id;
   }

   public void setId(Integer id)
   {
      this.id = id;
   }

   public String getCode()
   {
      return code;
   }

   public void setCode(String code)
   {
      this.code = code;
   }

   public String getName()
   {
      return name;
   }

   public void setName(String name)
   {
      this.name = name;
   }

   public Distrito getMyDistrito()
   {
      return myDistrito;
   }

   public void setMyDistrito(Distrito myDistrito)
   {
      this.myDistrito = myDistrito;
   }

   public Vector getMyFreguesia()
   {
      return myFreguesia;
   }

   public void setMyFreguesia(Vector myFreguesia)
   {
      this.myFreguesia = myFreguesia;
   }

   /**
    * 
    * @element-type Freguesia
    */
   public Vector   myFreguesia;
}

the configuration is the following (I have some part of it commented so I can switch from annotations to HBM files)

Code:

<?xml version='1.0' encoding='utf-8'?>

</session-factory>
</hibernate-configuration>

and the HBM files are the following

Code:

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="com.timestamp.database.datatypes">
    <class name="Concelho" table="CIOFE_CONCELHO">
        <id name="id" column="ID">
            <generator class="native"/>
        </id>
        <property name="code" column="CODE" length="10"/>
        <property name="name" column="NAME" length="100"/>
         <many-to-one name="myDistrito"
            column="ID_DISTRITO"
            class="Distrito" />
    </class>
</hibernate-mapping>

Code:

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="com.timestamp.database.datatypes">
    <class name="Freguesia" table="CIOFE_FREGUESIA">
        <id name="id" column="ID">
            <generator class="native"/>
        </id>
        <property name="code" column="CODE" length="10"/>
        <property name="name" column="NAME" length="100"/>
         <many-to-one name="concelho"
            column="ID_CONCELHO"
            class="Concelho" />
    </class>
</hibernate-mapping>

Im really lost here, because I really whanted do use anotations but had to switch to hbm beacause I was stuck

Thanks for the help
