Answer 1

here a typical code.
it works fine for me (see comments):
import java.sql.*;
public class MySQLTest {
     public static void main(String[] args) {
          Connection c = null;
          Statement stmt = null;
          ResultSet rs = null;
          String db = "your_db";
          String user = "username";
          String password = "password";
          try {
               /* Test loading driver */
               String driver = "com.mysql.jdbc.Driver";
               System.out.println("=> loading driver:");
               Class.forName(driver);
               System.out.println("Loading driver OK");
               /* Test the connection */
               String url = "jdbc:mysql://127.0.0.1:3302/" + db;
               System.out.println("=> connecting:");
               c = DriverManager.getConnection(url, user, password);
               System.out.println("Connecting OK");
               stmt = c.createStatement();
               rs = stmt.executeQuery("show tables");
               // Display result set meta data
               ResultSetMetaData rsmd = rs.getMetaData();
               int cc = rsmd.getColumnCount();
               for (int i = 1; i <= cc; i++) {
                    System.out.println(rsmd.getColumnName(i));
               //Display all tables
               int count = 0;
               while(rs.next()){
                    System.out.println(rs.getString("Tables_in_" + db));
                    count++;
               System.out.println("Found "+count+" Tables");
          } catch (Exception x) {
               x.printStackTrace();
          } finally {
               if (rs != null)
                    try {
                         rs.close();
                    } catch (Exception e) {
                         // TODO: handle exception
               if (stmt != null)
                    try {
                         stmt.close();
                    } catch (Exception e) {
                         // TODO: handle exception
               if (c != null)
                    try {
                         c.close();
                    } catch (Exception e) {
                         // TODO: handle exception
NB: use the correct username, password, url and port.
Hope that helps
