I am a newbie and am attempting to configure the Cat example program working with Oracle9ias app server (actually within JDeveloper, but hopefully that won't matter) and an Oracle9i database (using the JDBC OracleDriver from classes12.jar)

Contents of the hibernate.cfg.xml file:

<hibernate-configuration>
<!-- a SessionFactory instance listed as /jndi/name -->
<session-factory name="java:comp/env/intelinoDS">

<!-- properties -->
<property name="connection.datasource">jdbc/intelinoDS</property>
<property name="dialect">net.sf.hibernate.dialect.Oracle9Dialect</property>
<property name="show_sql">true</property>

<!-- mapping files -->
<mapping resource="ex/cat.hbm.xml"/>
</session-factory>

</hibernate-configuration>

============================================

Contents of the Cat.hbm.xml file:

<hibernate-mapping>

<class name="ex.Cat" table="CATS" discriminator-value="C">
<id name="id" column="id" >
<generator class="sequence"/>
</id>

<discriminator column="subclass" type="character"/>

<property name="birthdate" type="date"/>
<property name="color" not-null="true"/>
<property name="sex" not-null="true" update="false"/>
<property name="weight"/>

<subclass name="ex.DomesticCat" discriminator-value="D">
<property name="name" type="string"/>
</subclass>
</class>

</hibernate-mapping>

============================================

Here are the results:

Unfortunately this results in the following backtrace:

===========================================

Any help would be appreciated.

thanks, pugmaster

You forgot to copy cglib.jar to your classpath. Is it mentioned in the tutorial? :)

My bad.

I had copied all of the library jar files (as specified in the manual) into a central library location. But because JDeveloper is an IDE, it ALSO needs them copied to its central library repository.

I got confused because the beginning of the path (sf.net) is the same as for Hibernate. So I thought that the path for these libraries was being dynamically constructed (or in this case mangled) and was only looking for it within hibernate2.jar. Just never occurred to me to check elsewhere.

Thanks
