Problems in Hibernate executing stored procedure

Hi everyone,
first of all, i will say that i've looked during 2 days now in internet to find a solution but i couldn't find anyone.
my problem is: i cant run a stored procedure, my files are:
HBM:
<hibernate-mapping>
<class name="com.allence.opcapl.alpha2.common.model.dossieradherent.DossierAdherentList" >
<meta attribute="extends" inherit="false">com.allence.commons.model.BusinessObject</meta>

</id>

</return>
{call SEARCH_ADHERENT()}

</sql-query>
