Sample Main.java class for JDBC Driver stand-alone application -

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class Main {
    public static void main(String[] args) {
        String url = "jdbc:opensearch://https://ruh7jos10anqd6bsp844.beta-us-east-1.aoss.amazonaws.com?auth=aws_sigv4_serverless&region=us-east-1";
        try {

            Connection con = DriverManager.getConnection(url);
            Statement st = con.createStatement();

            ResultSet rs = st.executeQuery("SELECT * FROM target_index");
            System.out.println("**************** Execute Query: SELECT * FROM target_index");
            System.out.println("**************** Result set *****************");

            // Get the ResultSet metadata
            java.sql.ResultSetMetaData rsmd = rs.getMetaData();
            int columnsNumber = rsmd.getColumnCount();

            while (rs.next()) {

                for (int i = 1; i <= columnsNumber; i++) {
                    if (i > 1) System.out.print(",  ");
                    String columnValue = rs.getString(i);
                    System.out.print(rsmd.getColumnName(i) + ": " + columnValue);
                }
            }
        } catch (Exception e) {
            System.out.println("Exception :" + e.getMessage());
