java.sql.Statement; import java.sql.ResultSet; import java.sql.SQLException; import java.util.ArrayList;   public class ClienteListAction extends Action {  protected ArrayList getEmployees() {   Cliente cliente = null;   ArrayList clientes = new ArrayList();   Connection conn = null;   Statement stmt = null;   ResultSet rs = null;   ServletContext context = servlet.getServletContext();   DataSource dataSource = (DataSource) context.getAttribute(Action.DATA_SOURCE_KEY);   try {    conn = dataSource.getConnection();    stmt = conn.createStatement();    rs = stmt.executeQuery("select * from cliente ");    while (rs.next()) {     cliente = new Cliente();     cliente.setCodigo(new Integer(rs.getInt("codigo")));     cliente.setNome(rs.getString("nome"));     cliente.setEndereco(rsgetString("endereco"));     cliente.setUf(rs.getString("uf"));     cliente.setFone(rs.getString("fone"));     cliente.setSexo(rs.getString("sexo"));     clientes.add(cliente);     System.err.println("Cliente : " + cliente.getNome());    }   } catch (SQLException e) {    System.err.println(e.getMessage());   } finally {    if (rs != null) {     try

request,   HttpServletResponse response)   throws IOException, ServletException {   String target = "list";   ArrayList clientes = getEmployees();   return (mapping.findForward(target));  } }   4) Meu
