What did you put in the dialect property in your hibernate.cfg.xml file?

Thanks,

You made it clear that i have defined the dialect as net.sf
and now i changed it org.hibernate. Its working fine now...

I have another doubt , i.e In my hibernate.cfg.xml file i have more than 10 hbm.xml files and is it mandatory to change the DTD version to 3.0 in all my hbm.xml files...?

here is my hibernate.cfg.xml file

<?xml version='1.0' encoding='utf-8'?>

</session-factory>

</hibernate-configuration>

Right now i changed the DTD version for only one file named hotlink.hbm.xml...
plz tell me when migrating from hibernate 2.0 to 3.0 is it needed to change all the
hbm.xml's DTD..? Thanks in advance...

This is the dialect property which i've used in hibernate.cfg.xml
and it is mentioned below.


<property name="dialect">org.hibernate.dialect.Oracle9Dialect</property>


Still the same error is occuring...
