Empty pdf with Struts 1

[mackensen]

Hello,

I have a web app with Struts 1.2.9 and JasperReport 3.5.2.

The problem is that when I create an Action to generate a pdf I get an empty pdf. I created the .jrxml file with iReport 3.5.2 and I put on it just a static text.

I also tried to export to XML. I get the XML tree but there's only the name of the report so I presume that the path to the report is ok, I mean, the application gets the right report file.

Below is the code:

Thanx,
Mack
 

 

Code:

public ActionForward printPdf(ActionMapping mapping, ActionForm  form,            HttpServletRequest request, HttpServletResponse response)            throws Exception {                      ServletOutputStream out=response.getOutputStream();  //i also tried with OutputStream                response.setContentType( "application/pdf" );              JasperDesign jasperDesign=null;        JasperReport jasperReport=null;        String reportFile="";         reportFile=this.getServlet().getServletConfig().getServletContext().getRealPath("/reports/Print_indComm.jrxml");        Map parameters_header=null;                parameters_header=this.getParametersHeaderPdf(idComm);   //this method and parameter are defined             try {        jasperDesign = JRXmlLoader.load(reportFile);               jasperReport = JasperCompileManager.compileReport(jasperDesign);                JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters_header);                   JasperExportManager.exportReportToPdfStream(jasperPrint, out);                out.flush();        out.close();        }        catch (Exception ex)        {            String connectMsg = "Could not create the report " + ex.toString() + " " + ex.getLocalizedMessage();            response.setContentType("text/html;charset=UTF-8");            PrintWriter out1 = response.getWriter();            out1.println(connectMsg);            out1.close();        }              return mapping.getInputForward();    }

Hi,

 

When you fill your report, you don't provide any data source or DB

connection, do you?

 

In that case, you should set the "whenNoDataType" report property to

"AllSectionsNoDetail" or supply an instance of the JREmptyDataSource.

 

I hope this helps.
