Wie zu Bearbeiten jasper Datei?

wenn Sie einen IReport für die Bearbeitung Ihres .jrxml-Berichte, sollten Sie nur drücken Sie die Schaltfläche "Vorschau". Dann die .jasper report-Datei wird erzeugt, die automatisch in Ordner, die enthält das .jrxml-Datei

versuchen Sie dynamische Bericht.
Sie nicht einen Ort haben problem, wenn Sie erzeugen Ihren eigenen Bericht.
Beispiel;

public JasperDesign createDesign() throws JRException {
    JasperDesign jasperDesign = new JasperDesign();
    jasperDesign.setName("sampleDynamicJasperDesign");
    jasperDesign.setPageWidth(595); //page width
    jasperDesign.setPageHeight(842); //page height
    jasperDesign.setColumnWidth(515);   //column width of page
    jasperDesign.setColumnSpacing(0);
    jasperDesign.setLeftMargin(40);
    jasperDesign.setRightMargin(40);
    jasperDesign.setTopMargin(20);
    jasperDesign.setBottomMargin(20);

    JRDesignExpression expression = new JRDesignExpression();

    //Set style of page.
    JRDesignStyle normalStyle = new JRDesignStyle();
    normalStyle.setName("Sans_Normal");
    normalStyle.setDefault(true);
    normalStyle.setFontName("DejaVu Sans");
    normalStyle.setFontSize(12);
    normalStyle.setPdfFontName("Helvetica");
    normalStyle.setPdfEncoding("Cp1252");
    normalStyle.setPdfEmbedded(false);
    jasperDesign.addStyle(normalStyle);
