Core/examples/sessions/Broker example not working

Question

Guys
I am trying the example with Oracle database instead of the HSQL database. I replaced the driver & url strings and put the classes12.jar in the classpath
But I continue to get the following error. Can someone please tell me what I am missing.

One more thing to add:
I am not able to get any of the examples to work with Oracle database. Again the only thing I suppose I need to change are the folloowing lines in the EmployeeProject.java
     login.usePlatform(new oracle.toplink.internal.databaseaccess.OraclePlatform());
     login.setDriverClassName("oracle.jdbc.driver.OracleDriver");
     login.setConnectionString("jdbc:oracle:thin:@localhost:1522:fims");
     login.setUserName("kumarv");
     login.setEncryptedPassword("7AD96CD575D1A7FCAA504BA7E4FC");
Also one line change in the sessions.xml file to use the OraclePlatform instead of the HSQLPlatform.
Has any one got these to work with Oracle, Any help is really appreciated.
classes12.jar is in the classpath so I don;t understand why I get the execption that:
[java] EXCEPTION DESCRIPTION: Configuration error. Class [oracle.jdbc.driver.OracleDriver] not found.
[java] oracle.toplink.exceptions.DatabaseException oracle.toplink.exceptions.DatabaseException.configurationErrorCla
ssNotFound(java.lang.String)
Thanks
