entity class not found problem

Eclipse and hibernate versions: the latests.

When i try to execute my project, while creating a new session factory, my project trows a entity class not found exception. Let's see:

entity class not found: Usuarios

Caused by: org.hibernate.MappingException: entity class not found: Usuarios

However, everything seems ok for me. The mapping file:

Code:

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<!-- Generated 08-abr-2007 17:22:01 by Hibernate Tools 3.2.0.b9 -->
<hibernate-mapping>
    <class name="Usuarios" table="USUARIOS" schema="PUBLIC">
        <id name="nombreUsuario" type="string">
            <column name="NOMBRE_USUARIO" length="20" />
            <generator class="assigned" />
        </id>

        <property name="contrasenya" type="string">
            <column name="CONTRASENYA" length="10" not-null="true" />
        </property>
        <property name="tipoUsuario" type="string">
            <column name="TIPO_USUARIO" length="10" not-null="true" />
        </property>
    </class>
</hibernate-mapping>

is placed on the same package than the .java file

Code:

package negocio;

public class Usuarios {

   private String nombreUsuario;
....

and the hibernate config file is placed on the src root

Code:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
      "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
      "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.driver_class">org.hsqldb.jdbcDriver</property>
        <property name="hibernate.connection.url">jdbc:hsqldb:hsql://localhost/serviciomantenimiento</property>
        <property name="hibernate.connection.username">sa</property>
        <property name="hibernate.dialect">org.hibernate.dialect.HSQLDialect</property>
        <mapping resource="negocio/Usuarios.hbm.xml"/>
    </session-factory>
</hibernate-configuration>

I made some searchs about it and i guess the problem is related with classpath or alike, but i've been unable to solve it, so finally i am here asking for help.
Thanks in advance.

put the whole package name in the Usuarios.hbm.xml file

Code:

...
<hibernate-mapping> 
    <class name="negocio.Usuarios" table="USUARIOS" schema="PUBLIC"> 
      ...

hi, I am also encount this problem just like you, can you tell me how to solve this?
try{
// Create a configuration based on the properties file we've put
// in the standard place.
Properties prop=new Properties();
prop.load(new FileInputStream(propertyFileName));

Configuration config = new Configuration().addProperties(prop);
config.addClass(com.whu.iss.server.entity.MyGood.class);
config.addClass(com.whu.iss.server.entity.MyGoodclass.class);
config.addClass(com.whu.iss.server.entity.MyIndent.class);
config.addClass(com.whu.iss.server.entity.MyIndentlist.class);
config.addClass(com.whu.iss.server.entity.MyUser.class);
config.addClass(com.whu.iss.server.entity.MyGoodadminuser.class);
// Get the session factory we can use for persistence
sessionFactory = config.buildSessionFactory();
}catch(Exception e){
throw e;
}

}
this is my code, when execute to this line:
sessionFactory = config.buildSessionFactory();
it throw the
entity class not found: com.whu.iss.server.entity.MyGoodadminuser
exception
