Oracle install problem

[Toto Cottugno]

Hi,
I'm new to OpenReports
I'm installing release 1.0-M1  on Oracle 9.

-I've
-built from source and created War file.
-created all tables & hib sequence in a dedicated schema.
- manually created admin user.
- set dialect to net.sf.hibernate.dialect.Oracle9Dialect in hibernate properties file.

- now :
   I can connect with admin user but I always receive this message when I create any kind of object: org.efs.openreports.providers.ProviderException: Could not save object

The log show this kind of message :
java.sql.SQLException: ORA-00942: table or view does not exist
    at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134)
    at oracle.jdbc.ttc7.TTIoer.processError(TTIoer.java:289)
    at oracle.jdbc.ttc7.Oall7.receive(Oall7.java:582)

To solve , I just added the dialect declaration in hibernate.cfg.xml file.

<property name="dialect">   
   net.sf.hibernate.dialect.Oracle9Dialect
</property>

But why dialect is also declared in hibernate.properties ? is it required ?
