import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;

public class Register extends HttpServlet{
    public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException{

        response.setContentType("text/html");
        PrintWriter out=response.getWriter();

        String n=request.getParameter("name");
        String p=request.getParameter("password");
        String e=request.getParameter("email");
        String c=request.getParameter("userCountry");

        try{
            Connection con=DriverManager.getConnection(
                    "jdbc:mysql://localhost:8888/login", "root", "1234"
            );

            PreparedStatement ps=con.prepareStatement("insert into REGISTERUSER values(?, ?, ?, ?)");

            ps.setString(1,n);
            ps.setString(2,p);
            ps.setString(3,e);
            ps.setString(4,c);

            int i=ps.executeUpdate();
            if(i>0){
                out.print("Registered successfully..");
            }

        }catch(Exception d){d.printStackTrace();}
        out.close();
    }

    </select><br><br>

    <input type="submit" value="register">
</form>
</body>
</html>

Solution

In Java web applications, third party libraries go in WEB-INF/lib folder. Copy the jar inside this folder and redeploy your application. Do this in case your application should support these libraries on every application server (Tomcat, Jetty, JBoss, GlassFish, etc.) it will be deployed.

OTHER TIPS

No suitable driver suggests that the class loader found the JAR, but your connection URL is incorrect.

Here are the MySQL docs for Connector/J:

http://dev.mysql.com/doc/refman/5.0/en/connector-j-info.html

The default port for MySQL is 3306. Are you sure your local host is listening on 8888?

Bad code. Scriptlets don't belong in JSP. You don't close any SQL resources in finally blocks.

1)add driver jar file to your build path
2)add Class.forName("com.mysql.jdbc.Driver"); in your code.

eg: 

try{
Class.forName("com.mysql.jdbc.Driver");
        Connection con=DriverManager.getConnection(
                "jdbc:mysql://localhost:8888/login", "root", "1234"
        );
