Pessoal já gerei iReports usando queries SQL, mas agora me deparei com um problema, terei que gerar um relatório para todos os dados de uma JTable, já pesquisei e encontri um tal de iText, mas isso eu não posso usar com …

Usando JRBeanCollectionDatasource. Cada linha da JTable deve ser formada por atributos de uma classe e, o JRBeanCollectionDatasource deve receber uma coleção destes objetos como argumento.

Alguém tem algum exemplo de como eu uso isso? Devo instanciar na GUI e chamar de lá, criar outra classe, extender alguma classe? Toda ajuda é bem vinda, ainda mais nesses momentos de desespero!

JTable para iReport

Pessoal, fiz essa classe:

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&lt;Contato&gt; 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();
        } 
        
    }
}

que é chamada neste evento:

private void btnGeraEtiquetasActionPerformed(java.awt.event.ActionEvent evt) {                                                 
        geradorRelatorios.exibirRelatorio(relatorioTableModel.getDados());
    }

e tenho este stacktrace:
