Hi all,

I'm a new user of Hibernate so I tried to use a simple application bur I have a probem wih the Dialect. I use an Oracle 9i Database and when I run the programm I have this error :

If someone can help me.
Thanks

Looks like you have <generator class="identity"/> somewhere, which is not supported in Oracle.

Ok but where I can find the problem?
My configuration is :

hibernate.dialect net.sf.hibernate.dialect.Oracle9Dialect
hibernate.connection.driver_class oracle.jdbc.driver.OracleDriver
hibernate.connection.username hybernate
hibernate.connection.password hybernate
hibernate.connection.url jdbc:oracle:thin:@MCS-SRV-LD-01:1521:MCSDBDEV

In the jar hibernate2.jar I have find the good class but aulways the same problem.

Thanks

Ok Thanks a lot, I have find the problem :
the
<generator class="native"/> must be native and not identity
