questo è il codice del report in pratica ci sta un label con scritto nome : $P{NOME} con questo parametro .

questo è il codice che uso per richiamare il report

        HashMap hm = null;
        Map params = new HashMap();
        hm = new HashMap();
        hm.put("NOME", "123");
            String report = "C:\\Users\\Danilo\\Desktop\\preventivo.jrxml";
            JasperReport jasp_report = JasperCompileManager.compileReport(report);
            JasperPrint jasp_print = JasperFillManager.fillReport(jasp_report, hm);
            JasperViewer.viewReport(jasp_print);
