Java Database Connectivity (JDBC)

Hi,

I am using NetBeans6.0.1 and added iReports3.0 plugin.
while creating a report it is asking for the Database JDBC connection details to test the connection.
I provided the correct information(URL,username,password) and the oracle driver is also in the CLASSPATH.

But while testing, it is giving error like.

ClassNotFoundError!
Msg: oracle.jdbc.driver.OracleDriver
Possible not found class: oracle.jdbc.driver.OracleDriver
...
