Hi,
I think you have not provided the path of you MysqlConnector. jar to the class path. Try this.

Hi,
When I run your code in my system ..... It worked properly. So again I vil suggest you to check all your classpaths. Are you running your application from command prompt or in some IDE ?

1.) Use code tags
2.) How did you specify the path to the connector jar?

1.) Use code tags
2.) How did you specify the path to the connector jar?

What is meant by code tags?

D:\mysql-5.0.45-win32\mysql-connector-java-3.1.14\mysql-connector-java-3.1.14-bin.jar;%CLASSP ATH%

Hi,
I will suggest you to read some tutorials on classpath. I have found these, suitable for you ...
