Network adapter connection error

[Gina vernon]

Hi,
I am unable to connect to oracle via hibernate. This is the stack trace I get:

the connection properties are

  <property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="hibernate.connection.url">jdbc:oracle:thin:@locahost:1521:inst</property>  

The code runs on the same machine as the database. I bounced the database, including the extended connection URL. I have done everything but nothing seems to work. The driver I am using is Ojdbc6.jar.
Any help is appreciate.
Thanks.
