JDBC talking to MySQL

Question

Hi all,
I'm using NetBeans 4 as an IDE and i'm having some trouble with MySQL.
My program runs fine and i can update field on the MySQL when i'm running the program from within NetBeans but when i run the .jar file externally, there is an error that is caught that says as written below:
com.mysql.jdbc.driver
This is my code..... it's not very big but it's in 3 classes and i'm pretty new to coding so it's all over the place. I'll show the class that does the SQL work only because the others only call functions and parse in things for this class to do.
Any help would be appreciated i know i'm a little vague!!!

import javax.swing.JOptionPane;
import java.math.*;
import java.sql.*;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class SQLAccess
public SQLAccess()
//empty constructor
public SQLAccess(String name, int age)
String userName = "root";
String password = "root";
String url = "jdbc:mysql:///Storage";
Connection conn = null;
try
Class.forName("com.mysql.jdbc.Driver").newInstance();
conn = DriverManager.getConnection(url, userName, password);
if(!conn.isClosed())
System.out.println("Successfully connected to " +
"MySQL server using TCP/IP...");
Statement stmt = conn.createStatement();
//SQL command sequence to place a new entry into the table
String input = ("INSERT INTO info VALUES('" +
name + "' , '" + age + "')");
stmt.executeUpdate(input);
catch(Exception e)
System.err.println("Exception: " + e.getMessage());
JOptionPane.showMessageDialog(null, e.getMessage());
finally
try
if(conn != null)
conn.close();
catch(SQLException e) {}

Answer 1

i put
-classpath .;"C:\Program
Files\Java\jdk1.5.0_02\jre\lib\extmysql-connector-java
-3.1.8-bin.jar" but it still don't work.
it just ain't goin well for me today...but i do agree
about the windows classpath part.....that would add
the path for every future compile so thanks for the
tip :)
Presumably you are still getting the class not found exception.
The above is not a complete command line. As a guess you are still running it as an executable jar.
You have a choice. You will need to do one of the following.
1. Run it as a jar, not an executable jar.
2. Figure out how manifests work. An executable jar ignores all forms of external class path (command line and env vars.) Basically you have to include the driver jar in the executable jar and create a manifes that tells the jar that the driver is in there. There are examples of this in the forums somewhere.
