Hi all,
Is the first time that I use Hibernate in a web application project, I have a problem using "HQL Query".
The "Hibernate Mapping Files and POJOs" and HibernateUtil are created by wizard.

IDE:
NetBeans 6.5.1

Frameworks used:
Spring web MVC 2.5
Struts 2
Hibernate 3.2.5

Informix drivers:
ifxjdbc.jar
ifxjdbcx.jar
ifxlang.jar
ifxlsupp.jar
ifxsqlj.jar
ifxtools.jar

hibernate.cfg.xml:
<?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.dialect">org.hibernate.dialect.InformixDialect</property>
<property name="hibernate.connection.driver_class">com.informix.jdbc.IfxDriver</property>
<property name="hibernate.connection.url">jdbc:informix-sqli://atmsrv26:1526/dbprova:informixserver=csaol1tcpw</property>
<property name="hibernate.connection.username">XXXX</property>
<property name="hibernate.connection.password">YYYYYYYY</property>
<property name="hibernate.show_sql">true</property>
<property name="hibernate.current_session_context_class">thread</property>
<mapping resource="hib/Tbutenti.hbm.xml"/>
<mapping resource="hib/Tbcenlav.hbm.xml"/>
<mapping resource="hib/Tbprofil.hbm.xml"/>
</session-factory>
</hibernate-configuration>

hibernate.reveng.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-reverse-engineering PUBLIC "-//Hibernate/Hibernate Reverse Engineering DTD 3.0//EN"

"http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd">

<table-filter match-name="tbcenlav"/>
<table-filter match-name="tbprofil"/>
<table-filter match-name="tbutenti"/>
</hibernate-reverse-engineering>

query:
from Tbutenti

SQL:
select tbutenti0_.idutente as col_0_0_ from dbprova.DBPROVA.tbutenti tbutenti0_

error:
