image missing in xml

2003-10-01 14:26

Hello. I'm using jasperreports 0.5.0 with java 1.4.1 on Windows XP. I use IE 6.0.28 to display reports.

 

I export to a xls byte array using JRXmlExporter. Here is the code:

 

--------------------------------------------------

public static byte[] exportReportToXls(JasperPrint jasperPrint)

throws JRException

{

JRXlsExporter exporter = new JRXlsExporter();

 

ByteArrayOutputStream xlsReport = new ByteArrayOutputStream();

exporter.setParameter(JRHtmlExporterParameter.IMAGES_MAP, new HashMap());

exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);

exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, xlsReport);

 

exporter.exportReport();

return(xlsReport.toByteArray());

}

--------------------------------------------------

 

After that, I use this function in a servlet to display the report on screen:

 

--------------------------------------------------

pdf = exportReportToXls(jasperPrint);

response.setContentType("application/vnd.ms-excel");

response.setHeader("Expires", ""); //-IE-

response.setHeader("Cache-Control", "");//-IE-

response.setHeader("Pragma", "");//-IE-

response.setContentLength(pdf.length);

response.getOutputStream().write(pdf);

response.getOutputStream().flush();

response.getOutputStream().close();

 

 

 

--------------------------------------------------

 

The report display images passed by parameters. There is no problem in html or pdf, but the xml result not display any images. What's the problem?

Hi,

 

The POI library that we use to generate XLS

content simply does not support images.

 

Thank you,

Teodor
