Solución: "org.hibernate.hql.ast.querysyntaxexception is not mapped from" en español

Ya entrado en esto del Hibernate, me he dado cuenta que metí completamente la pata al querer realizar una consulta en HQL (Hibernate Query Languaje), como sabrán, si vamos a hacer una consulta equivalente al SQL por ejemplo: 

select * from registro_usuarios;

Su equivalente en HQL es:

from RegistroUsuarios  

OJO por favor, en la consulta HQL escribimos "RegistroUsuarios" en lugar de "registro_usuarios", esto es porque se hace referencia al bean (o bien a la clase RegistroUsuarios.java, para los no natos) que mapea a la tabla "registro_usuarios". Si comenten el error de escribir la consulta HQL de la manera:

from registro_usuarios

entonces obtendrán la espantosa excepción:

org.hibernate.hql.ast.querysyntaxexception registro_usuarios is not mapped from Registro_Usuarios

Bueno espero que les haya sido de ayuda, saludos...

The survey of recruiters and human resource professionals also found very high demand for C#, .Net, Oracle, Sharepoint, and SAP skills, as well as security analysts, people with federal security clearances, and database administrators. New York leads the way with more than 8,200 openings, followed by Washington, D.C., with 7,400, Silicon Valley with 4,400, and Chicago and Los Angeles with more than 2,800 each. Atlanta, Seattle, and Dallas have more than 2,000 IT job openings each, and Philadelphia has more than 1,600 openings.
