Hi,

I am just trying to do a simple insert with a many-to-one association. I am getting an association references an unmapped class exception.



Hibernate version: 3.0.5

Mapping documents:

hibernate-cfg.xml
<session-factory>

<property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="connection.url">jdbc:oracle:thin:@skanchirajulptp:1521:TEST</property>
<property name="connection.username">scott</property>
<property name="connection.password">scott</property>
<property name="connection.schema">scott</property>

<property name="dialect">org.hibernate.dialect.OracleDialect</property>

<property name="show_sql">true</property>

<property name="hbm2ddl.auto">create-drop</property>

<mapping resource="Imdscannedconfig.hbm.xml"/>
<mapping resource="Net.hbm.xml"/>

net.hbm.xml
<class name="com.hibernate.example.pos.Net" table="NETS">

<id name="id" >
<column name="NET_ID" not-null="true"/>
<generator class="sequence"/>
</id>

<property name="name">
<column name="NET_NAME"/>
</property>

<set name="imdscannedconfig"
inverse="true"
cascade="save-update">
<key column="NET_ID"></key>
<one-to-many class="Imdscannedconfig"/>
</set>

</class>

imdscannedconfig.hbm.xml
<class name="com.hibernate.example.pos.Imdscannedconfig" table="IMDSCANNED">

<id name="id">
<column name="IMDS_ID" not-null="true"/>
<generator class="sequence"/>
</id>

<property name="configName">
<column name="IMDS_NAME" length="16" not-null="true"/>
</property>

<many-to-one name="net"
column="NET_ID"
class="Net"
not-null="true"/>
</class>



Code between sessionFactory.openSession() and session.close():

Net testnet = new Net();
testnet.setName("Net 1");
Imdscannedconfig candConfg = new Imdscannedconfig();
candConfg.setConfigName("Test Canned Configuration");
testnet.addImdscannedconfig(candConfg);
sess.save(testNet);

code for addImdscannedconfig()
public void addImdscannedconfig(Imdscannedconfig imdscand)
{
imdscand.setNet(this);
this.getImdscannedconfig().add(imdscand);

}

Name and version of the database you are using:
Oracle 10g

Thanks in advance for the help.

in net.hbm.xml change

Thanks Nathan.

Missed that package details.

Could be a best practice to give the package name at the top of the mapping file.
