I am getting the following error, when a call is made at session.flush()

I am using Oracle9. I am not using oracle thin driver. On windows, I configure JDBC-ODBC bridge and datasource name is - test.

When, I ran following code it woked fine for me.

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection conn = DriverManager.getConnection ("jdbc dbc:test","scott","tiger");

Below is my configuration file.
-------------------------------------------------------------------------------------------
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="hibernate.connection.url">jdbc dbc:test</property>
<property name="hibernate.connection.username">scott</property>
<property name="hibernate.connection.password">tiger</property>
<property name="hibernate.connection.pool_size">1</property>
<property name="show_sql">true</property>
<property name="dialect">org.hibernate.dialect.Oracle9Dialect</property>
<property name="hibernate.hbm2ddl.auto">update</property>
<!-- Mapping files -->
<mapping resource="myemp.hbm.xml"/>
</session-factory>
</hibernate-configuration>

The error

I think, there is problem with Driver/Dialect class but not sure.

Hi Ghulam,

Your error log is also giving the following error, as root cause

----------------------------------------------------------
Caused by: java.sql.SQLException: No suitable driver
-----------------------------------------------------------

Please check for the appropriate driver to connect to Oracle 9 database from java.

Thanks
DJDON

Tahnks, Its problem with the driver. Does Hibernate support Type-1 JDBC driver?

It worked, when I changed my URL to jdbc racle:thin:@localhost:1521:actualdbname from jdbc dbc:test. Where test is the JDBC-ODBC configuration from control center .....
I am not sure whether Hibernet supports Type-1 driver, which requires client configuration on client machine.

Thanks
