API and Database updates

Question

Greetings!
I've searched the archives for the forum and I can't find anything relating to my issue, so hopefully someone will have an idea of how I can get started on a new project.
I have an SQL database that contains a row for each hour of each day. Every row contains a date (obviously for every one day there are 24 rows), an hour interval (1:00pm), the day of the month, the day of the week (Saturday), the Meridian, the Military time conversion (13:00), the week of the year, etc. This database is used for reporting purposes and it runs out of rows as of next week. I have been tasked with adding enough rows to last us another 2 years, which is about 17,000 rows.
My colleague mentioned that I might be able to find what I need in the API and then write a little Java program that interfaces with my database to update the rows. Being completely new, I'm a little unsure as to how to go about researching this.
I did poke in the API and I found the DateFormat class in the java.text package. It seems to have just about everything I need except for the military conversion.
Does anyone have any thoughts on how I could use this class to write out these future rows to the database? One thing I should mention is that each row has a unique row-identifier that increments sequentially.
If I have been unclear, please let me know and I will try to clarify. Any help or a nudge in the right direction would be greatly appreciated!
Thank you!

Java can acces SQL databases through JDBC. Here is a
JDBC tutorial that can help you get started:
http://java.sun.com/docs/books/tutorial/jdbc/index.htm
i have looked at this tutorial yet there is a problem that i cant really deal with:-
* am using net beans (windows xp), mysql server, and j/connector driver.
* in net beans, in the RealTime Tab i can access my database in MySQL, but every time i write my code (in java)so i can connect with it and manipulate its tell me :
SQLException: No suitable driver
SQLState: 08001
VendorError: 0
my question is why can i access my database through 'Databases' in 'RealTime' tab, and not be able to make a simple connection with it when i run a simple code like this:
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class LoadDriverP {
public static void main(String[] args) {
try {
Class.forName("com.mysql.jdbc.Driver");
} catch (Exception ex) {
// handle the error
try {
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/world"," user", "pass");
// Do something with the Connection
} catch (SQLException ex) {
// handle any errors
System.out.println("SQLException: " + ex.getMessage());
System.out.println("SQLState: " + ex.getSQLState());
System.out.println("VendorError: " + ex.getErrorCode());
could it be anything to do with CLASSPATH if it is please tell me what is this CLASSPATH and how can i change it.
any help would be greatly apreaciated.
