I am developing Jasper reports.
I know how to write the xml file.I have the required java file.
But my problem is with connecting to the database.
I am getting the error

java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver

I am using oraclethin which is running on Tom cat server.

Can you help me out where to place the driver files and also the syntax for driver,url,user and password....

Or else can you suggest some tool from which we can build our jasper reports easily...

Thanking you,
