Hi,

I'm having a "no persistent classes found" error and this error not always occur.

I have the following mapping:

<class name="DemographicAssociation" table="demographic_association">

<composite-id name="demographicAssociationPK"
class="top.demography.core.DemographicAssociationPK" >

<key-property name="demographicGroupId"
column="demographic_group_id" type="java.lang.Integer" />
<key-property name="userId" column="user_id" type="java.lang.Integer" />
</composite-id>

</class>

In a test class i'm doing the next query:


....
Query query = session.createQuery ( "select b.demographicAssociationPK.demographicGroupId from top.spectaris.demography.core.DemographicAssociation as b where b.demographicAssociationPK.userserId = ?" );

query.setParameter ( 0, new Integer ( 50 ) );
Collection collection = query.list ();
userEntry.addGroups ( collection );
....

This code and query in the testing class works fine!

Now in the real application i've the same query (with the same mapping/s) and when i execute that query i get the error:

"no persistent classes found for query"


Any, ideas?

Regards,

Diego.
