Problem Getting Started with oracle database from Hibernate ?

[signor Rhena]

Any idea ?
I am following every steps on
http://www.hibernate.org/152.html
Getting Started
Day 1: Download and Install Hibernate
a. Download Hibernate and extract the archive
(Done succesfully Hibernate 3.0.5, expand in C dir so hibernate
is in C:\hibernate-3.0 )

b. Place your JDBC driver jar file in the lib directory
(I am using oracle database so I did copy classes12.jar file to
C:\hibernate-3.0\lib)

c. edit etc/hibernate.properties, specifying connection settings for your database (Hibernate will create a schema for the demo automatically)
I just did this for Oracle

#hibernate.dialect org.hibernate.dialect.OracleDialect
hibernate.dialect org.hibernate.dialect.Oracle9Dialect
hibernate.connection.driver_class oracle.jdbc.driver.OracleDriver
hibernate.connection.username scott
hibernate.connection.password tiger
hibernate.connection.url jdbc racle:thin:@GRDP01USG74053:1521:rambodb

I got error ? saying

Are you sure your connection url is correct?

[signor Rhena]

Yes it is ? I did test using some Java test program? It did work?
hibernate.connection.url jdbc oracle:thin:@GRDP01USG74053:1521:rambodb
