JasperParameter.put("foo", params.get(k).get(2).toString()) //where "foo" is a field in your iReport. JRDesignQuery query = new JRDesignQuery() Ĭonnection con = db.getConnection() //my own class that creates a sql connectionįor(int k = 0 k jasperParameter = new HashMap() If you put this into a for-loop with a query that updates itself, and fills report with new "jasperParameter"s, you will get several pages in your "test.pdf", with one page pr element/query. JasperPrint = JasperFillManager.fillReport(jasperReport, jasperParameter, con) Įxp.setParameter(JRPdfExporterParameter.JASPER_PRINT_LIST, list) Įxp.setParameter(JRPdfExporterParameter.OUTPUT_FILE, new File("test.pdf")) Make _damn_ sure your iReport and jasper jars are of the same version.version 4.0.0 actually produces ".jrprint" files when "fillReport" is used.
