Я пытаюсь получить данные, которые у меня есть в JTable, и распечатать их как отчет с помощью Jasper Reports. Я нашел Usando o JRBeanCollectionDataSource и Java beans как источник данных Jasper Reports с использованием JRBeanCollectionDataSource в качестве примеров для создания моего собственного кода:
package Negocio.Relatorios;
import Negocio.Contato;
import java.io.InputStream;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JasperFillManager;
import net.sf.jasperreports.engine.JasperPrint;
import net.sf.jasperreports.engine.data.JRBeanCollectionDataSource;
import net.sf.jasperreports.view.JasperViewer;
public class DataFromRelatorios{
public void exibirRelatorio(List<Contato> contatos){
String caminhoJasper = "./etiquetas.jasper";
JRBeanCollectionDataSource dataSource = new JRBeanCollectionDataSource(contatos);
Map parameters = new HashMap();
JasperPrint printer;
InputStream relJas = getClass().getResourceAsStream(caminhoJasper);
try {
printer = JasperFillManager.fillReport(relJas, parameters, dataSource);
JasperViewer viewer = new JasperViewer(printer, true);
viewer.setVisible(true);
}
catch (JRException ex) {
ex.printStackTrace();
}
}
}
Этот класс вызывается при возникновении ActionEvent:
private void btnGeraEtiquetasActionPerformed(java.awt.event.ActionEvent evt) {
geradorRelatorios.exibirRelatorio(relatorioTableModel.getDados());
}
Это мой след:

Я думал, что у меня есть все необходимые библиотеки для Jasper Reports, но какой из них мне не хватает?
