Good afternoon Gentlemen!
I have a problem and none of the other posts could help me...
I was checking my TCC and I just came across the following problem: My executable. JAR cannot identify the folder where the reports created by iReport version 5.6.0 are located.
In my project, I have a folder br.integrado.Ports where I keep all of mine . Besides having already imported the iReport libraries to the project.
This is my code for "printing" the report:

public class RelatorioService {

private static final String FOLDER = "/br/integrado/reports";

public void gerarRelatorio(HashMap parametros, String nomeRelatorioJasper) throws JRException {

    String caminhoRelatorio = this.getClass().getResource(FOLDER).getPath();
    String caminhoArquivosJasper = caminhoRelatorio + File.separator + nomeRelatorioJasper + ".jasper";

    JasperReport relatorioJasper = (JasperReport) JRLoader.loadObjectFromFile(caminhoArquivosJasper);

    JasperPrint impressoraJasper = JasperFillManager.fillReport(relatorioJasper, parametros, ConexaoJDBC.getConexao());

    JasperViewer jrv = new JasperViewer(impressoraJasper, false);
    jrv.setVisible(true);
    jrv.toFront();
}

}

In netbeans works perfectly, but in . jar it generates me the following Exception by CMD:

Could someone help me?

java exception netbeans ireport

  • Try String caminhoRelatorio = RelatorioService.class.getResourceAsStream(FOLDER). Please let me know if it works.

  • Good morning! I followed your instructions and in netbeans works perfectly, unfortunately the executable still has Nullpointer error. The following is the code: http://prntscr.com/ln5gyh

  • This is the error generated in cmd next to the file path: http://prntscr.com/ln5hmi

  • And this is the directory of my dist: http://prntscr.com/ln5i20

Solved:

public void gerarRelatorio(HashMap parametros, String nomeRelatorioJasper) {
    try {
        JasperPrint relatorio = null;
        JasperReport jasperReport = null;
        InputStream jasperFile = Thread.currentThread().getClass().getResourceAsStream("/br/integrado/reports/" + nomeRelatorioJasper + ".jasper");
        jasperReport = (JasperReport) JRLoader.loadObject(jasperFile);
        relatorio = JasperFillManager.fillReport(jasperReport, parametros, ConexaoJDBC.getConexao());
        JasperViewer viewer = new JasperViewer(relatorio, false);
        viewer.setTitle("Relatório");
        viewer.setVisible(true);
        viewer.toFront();
    } catch (JRException e) {
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    }
}
