I made a simple MySQL connection program but it doesn't work.
package main;
import java.sql.*;
public class Main {
static Connection con = null;
static Statement stmt = null;
static ResultSet rs = null;
static String url = "jdbc:mysql://localhost:3306/phpmyadmin";
static String user = "root";
static String password = "(i dont show this ;)";
public static void main(String[] args) {
try {
System.out.println("Connecting database...");
con = DriverManager.getConnection(url, user, password);
System.out.println("Database connected!");
} catch (SQLException e) {
throw new RuntimeException("Cannot connect the database!", e);
} finally {
System.out.println("Closing the connection.");
if (con != null) try { con.close(); } catch (SQLException ignore) {}
}
}
}
I got this error:
Connecting database...
Closing the connection.
Exception in thread "main" java.lang.RuntimeException: Cannot connect the database!
at main.Main.main(Main.java:22)
Caused by: java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/phpmyadmin
at java.sql.DriverManager.getConnection(Unknown Source)
at java.sql.DriverManager.getConnection(Unknown Source)
at main.Main.main(Main.java:19)
I made the buildpath, and I moved the files (from the connector) from the lib folder to \xampp\mysql\lib
. I also started tomcat (I didn't change any configs) and it is still not working.

You are missing some important steps like following
Class.forName("com.mysql.jdbc.Driver");
You can use the below link for complete instructions
http://www.mkyong.com/jdbc/how-to-connect-to-mysql-with-jdbc-driver-java/
import java.sql.DriverManager;
import java.sql.Connection;
import java.sql.SQLException;
public class JDBCExample {
public static void main(String[] argv) {
System.out.println("-------- MySQL JDBC Connection Testing ------------");
try {
Class.forName("com.mysql.jdbc.Driver");
} catch (ClassNotFoundException e) {
System.out.println("Where is your MySQL JDBC Driver?");
e.printStackTrace();
return;
}
System.out.println("MySQL JDBC Driver Registered!");
Connection connection = null;
try {
connection = DriverManager
.getConnection("jdbc:mysql://localhost:3306/mkyongcom","root", "password");
} catch (SQLException e) {
System.out.println("Connection Failed! Check output console");
e.printStackTrace();
return;
}
if (connection != null) {
System.out.println("You made it, take control your database now!");
} else {
System.out.println("Failed to make connection!");
}
}
}
