Hi,
I'm trying to access db Oracle by simple query:

String query = "from it.app.iniziative.Progetto";

where mapping file is

<hibernate-mapping>

<class name="it.app.iniziative.Progetto" table="PROJECTS">

<id name="idPRG" type="int" unsaved-value="null" >
<column name="KCODE" sql-type="number(12)" not- null="true"/>
<generator class="sequence" >
<param name="sequence">S_PROJECT</param>
</generator>
</id>

<property name="replanningQuantity" >
<column name="REPLANNINGQUANTITY" sql-type="number(12)"/>
</property>

<property name="status" sql-type="number(1)>
<column name="STATUS" />
</property>
</class>

</hibernate-mapping>


As the column STATUS has no value in db, in the log appears:

ERROR [http8070-Processor7] - [SYSTEM] Null value was assigned to a property of primitive type setter of it.app.iniziative.Progetto.status


ERROR [http8070-Processor7] - [SYSTEM] No persister for: java.lang.Integer


What can I do? Why doesn't the system find a class persister for Integer?
Thanks,
Anna

Use a custom UserType which maps null to some default value.
