Question

I am getting this error when trying to start up my hibernate. I am a hibernate newbie so was hoping someone could point out the mistake I made with my cfg. I included the error, hope it is an easy fix, thanks.

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

    <!-- Database connection settings -->
    <property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
    <property name="connection.url">jdbc:oracle:thin:@localhost:1521:orcl"</property>
    <property name="connection.username">scott</property>
    <property name="connection.password">tiger</property>
    <property name="hibernate.dialect" value="org.hibernate.dialect.OracleDialect"/>
    <!-- Echo all executed SQL to stdout -->
    <property name="show_sql">true</property>
</session-factory>

Try using
<property name="hibernate.dialect">org.hibernate.dialect.OracleDialect</property>

As a newbie, you can read entire hibernate documentation at
