Consegui fazer dota parte do prompt, criei as tabelas e tal. quando fui executar o código, do eclipse, de conexão com o banco deu nisso.

Codigo do eclipse:

<red>

 package br.com.caelum.jdbc;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class TestaConexao {
    public static void main(String[] args) throws SQLException {
        Connection connection = DriverManager.getConnection("jdbc:hsqldb:hsql://localhost/loja-virtual", "SA", "");
        System.out.println("Abrindo uma conexao com sucesso");
        connection.close();
    }
}

</red>
