Why am I getting these runtime errors? Cannot connect to database (Netbeans with sql db)

Ok,

1. The database is present. I have successfully run the sql query file开发者_高级运维.

2. I have included the bin.jar reference library to connect to the db.

When I run the program i get:

Cannot connect to database server

Can someone construe from this or have any ideas why I can't connect to the db server?

A NULL Pointer exception means that a reference has not been initialized. Did you forget to call "New" on something? You probably need a db connection object instance of some sort.
