eu fiz assim
classe para o relatorio

import net.sf.jasperreports.engine.*;   
import net.sf.jasperreports.view.*;   
import java.sql.*;   
import java.util.*;  
/**

 */
public class VendaRel {

    
 public void VendaRel(ResultSet rs) throws JRException  {

            JRResultSetDataSource jrRS = new JRResultSetDataSource( rs );   
                       
            Map parameters = new HashMap();   
 
     JasperPrint jprint = JasperManager.fillReport("C:\teste\relatorios\Cliente.jasper", parameters, jrRS);  //aqui onde esta o .jasper no meu caso Cliente
   
            JasperViewer.viewReport(jprint,false);   

        }   
      
}  

perceba que o construtor dessa classe esta esperando um RESULTSET

a funcao q returna esse resultset
   public ResultSet listarRelCliente(String Nome_Cliente) {
        String sql = "SELECT * FROM Cliente WHERE UPPER(nome_cliente) LIKE ?";
        try {
            PreparedStatement stmt = getConexao().prepareStatement(sql);
            stmt.setString(1, "%" + Nome_Cliente.toUpperCase() + "%");
            ResultSet rs = stmt.executeQuery();
         
            return (rs);
            
        } catch (SQLException sQLException) {
            System.out.println("Erro ao listar Cliente");
        }
        return null;
    } 

retorna todos os clientes que contem a string EX fabio vai retornar todos osclientes fabio se deicharmem branco retorna todos

aqui chamo esses metodos

     ClienteDao cliente = new ClienteDao();
            ClienteRel cli = new ClienteRel();

                ResultSet rs = cliente.listarRelCliente(campo_pra_pesquisaNome.getText()); //aqui pego em um campo texto o nome

                try {

                 cli.ClienteRel(rs);
                } catch (Exception ex) {
                    Logger.getLogger(ConsultarCliente.class.getName()).log(Level.SEVERE, null, ex);
                }


aqui funcionou beleza
