I have a many-to-one association. When I get the first object, I evict it from the session (I use session.clear() to evict all objects). Because I set lazy="no-proxy" for the association, the object associated is not loaded. I want to use my service to populate the associated object but I have some difficulties because hibernate initializes a proxy on it and load the object from database when I use setter methods on this object. (I use hibernate 3.1.2)

-------------------------------------------------------

Here are the mapping files :

<hibernate-mapping package="com.cwsoft.commons.model.businessobject">
<class name="Ccd01" table="CCD01">
<id name="numcpt" type="java.lang.String" column="NUMCPT" >
<generator class="assigned"/>
</id>
<property name="numcli" column="NUMCLI" type="string"/>
<many-to-one name="typcpt" column="TYPCPT" class="Tad01" lazy="no-proxy" cascade="evict"/>
</class>
</hibernate-mapping>

<hibernate-mapping package="com.cwsoft.commons.model.businessobject">
<class name="Tad01" table="TAD01">
<id name="argtbl" type="java.lang.String" column="ARGTBL" >
<generator class="assigned"/>
</id>
<property name="numtbl" type="string" column="NUMTBL" />
<property name="libel1_1" column="LIBEL1_1" type="string" />
</class>
</hibernate-mapping>

----------------------------------------------------------------------

And the test :

Session session = HibernateUtil.currentSession();
Transaction tx = session.beginTransaction();

Ccd01 ccd01 = (Ccd01)session.get(Ccd01.class,"999000000171");
session.clear();
Tad01 tad01 = ccd01.getTypcpt();
System.out.println("jba argtbl "+tad01.getArgtbl());
System.out.println("jba setNum");
tad01.setNumtbl("300");
System.out.println("jba setNum is set");

tx.commit();
HibernateUtil.closeSession();

-----------------------------------------------------------------------

And here are the logs between System.out.println("jba argtbl "+tad01.getArgtbl()); and System.out.println("jba setNum is set");
