Running jdbc methods from my application

I have a jdbc.class which executes queries etc.

I also have an application class.

When the app runs I'd like to to execute some methods in the jdbc to perform queries, how do I go about doing this?

I know how to call methods but I have to pass the connection paramter which has not been setup in my applicatoin class.

Thanks,

Jacob,
I would recommend having a separate class that handles creating the connection. Then your class containing the JDBC can call it and you don't need to pass the connection around all over.
