I'm using an older Spring 2 application with Tomcat and Hibernate. I was under the impression that I could change some settings in hibernate.cfg.xml, restart Tomcat, and the new settings (like a database connection) would take effect. Yet the old settings persist. What do I have to do to make these new changes go through? Here is an example of the xml:

```
<property name="connection.username">career</property>
    <property name="connection.url">jdbc:oracle:thin:@192.168.76.46:1521:ISDD</property>
    <property name="dialect">org.hibernate.dialect.Oracle9Dialect</property>
    <property name="myeclipse.connection.profile">my-careers</property>
    <property name="connection.password">farcri</property>
    <property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>

```

Let me know if more information is required.
