error in hibernate query

my hibernate.cfg.xml is this :

<?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">

<mapping class="entities.MisurazioneOraria"/>
<mapping class=....
    ....>
<listener type="post-insert" class="MisurazioneOrariaInsertListener"/>

</session-factory>

</hibernate-configuration>

i try to do query from this line code that is the listener :

ArrayList<MisurazioneOraria> mis =  (ArrayList<MisurazioneOraria>)    session.createQuery("from (misurazione_oraria) where sensore_idsensore = :idsensore").setParameter("idsensore", m.getSensore().getIdSensore()).list();

and the error is that :

mag 27, 2012 6:30:33 PM org.hibernate.event.def.AbstractFlushingEventListener   performExecutions
Grave: Could not synchronize database state with session
org.hibernate.QueryException: in expected: misurazione_oraria [from (misurazione_oraria) where sensore_idsensore = :idsensore]

my mysql version is 5.5.23. thanks for the help.

change it to 

List<MisurazioneOraria> mis = session.createQuery("from MisurazioneOraria where idSensore = :idsensore").setParameter("idsensore", m.getSensore().getIdSensore()).list();

Your entity class is named MisurazioneOraria, not misurazione_oraria. HQL uses entities and fields/properties. It doesn't use table and column names.

Read the HQL documentation.

Moreover, Query.list() returns a List, and not necessarily an ArrayList. You shouldn't cast the result of the query to ArrayList.
