Connecting to MySQL Database - GAE - AWS - Maven

I am receiving data in a Java Servlet (maven) and want to store it in a MySQL database that is hosted at Amazon. The application is hosted at Google.

I receive the error message "no suitable driver found for..."

I already added the mysql-connector-java-5.1.18-bin.jar to the folder WEB-INF/lib

This is my code:

package com.example.mail;

import java.io.IOException; 
import java.util.Properties; 
import javax.mail.Session; 
import javax.mail.internet.MimeMessage; 
import javax.servlet.http.*; 
import javax.mail.Address;
import java.sql.Statement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.util.logging.Logger;

public class MailHandlerServlet extends HttpServlet { 
    @Override
    public void doPost(HttpServletRequest req, HttpServletResponse resp) 
            throws IOException { 
                Properties props = new Properties(); 
                Session session = Session.getDefaultInstance(props, null); 

            try{    
                MimeMessage message = new MimeMessage(session, req.getInputStream());
                String summary = message.getSubject();
                Address[] addresses = message.getFrom();
                String text = message.getContent().toString();
                System.out.println("Subject: " + summary);
                System.out.println("Sender: " + addresses);
                System.out.println("Text: " + text);   

            } catch (Exception e) {
                e.printStackTrace();
            }

            String connectionUrl = "jdbc:http://mysqlaws-address:port/table";
            String dbUser = "user";
            String dbPwd = "pw";
            Connection conn = null;

            try {
                conn = (Connection) DriverManager.getConnection(connectionUrl, dbUser, dbPwd);
                System.out.println("conn Available");
            } catch (SQLException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
                System.out.println("fetch otion error"+e.getLocalizedMessage());
            }
    }
}

Thank you for your help!
