Your Oracle driver jar file is not on the runtime classpath.
How you run this will determine how it gets fixed.

As a note, code should be posted in code tags to retain formatting.
And do not eat exceptions. At the very least printStackTrace().
And finally you should close your resources (resultset, stetamenet, connection) in a finally block.
