Hi.
I made a little report with iReport, then I populated it from java code. I
tested it in the report viewer and everything goes right. Then, I added code
for export to HTML and inmediately send it to the browser, but my report
appears without images, wich are actually a chart. Any idea about the
problem? This is the code I use:
List alumnos = new ArrayList();
for(int i=0;i<5;i++){
AlumnoBean alumno = new AlumnoBean("Marcos"+i,new
Integer(23),new Long(i*2) );
alumnos.add(alumno);
}
JRBeanCollectionDataSource ds =new
JRBeanCollectionDataSource(alumnos);
//Create compiled .jasper:
File reportFile = new
File(servlet.getServletContext().getRealPath("reportes/reporteAlumnos3.jrxml"));
JasperDesign jasperDesign =
JasperManager.loadXmlDesign(reportFile.getPath());
JasperReport jasperReport =
JasperManager.compileReport(jasperDesign);
//create JasperPrint:
JasperPrint
jasperPrint=JasperFillManager.fillReport(jasperReport,new HashMap(),ds);
//exporting:
try{
PrintWriter printWriter=response.getWriter();
JRHtmlExporter htmlExporter=new JRHtmlExporter();
response.setContentType("text/html");
request.getSession().setAttribute(ImageServlet.DEFAULT_JASPER_PRINT_SESSION_ATTRIBUTE,jasperPrint);
htmlExporter.setParameter(JRExporterParameter.JASPER_PRINT,jasperPrint);
htmlExporter.setParameter(JRExporterParameter.OUTPUT_WRITER,printWriter);
Map imagesMap=new HashMap();
request.getSession().setAttribute("IMAGES_MAP",imagesMap);
htmlExporter.setParameter(JRHtmlExporterParameter.IMAGES_MAP,imagesMap);
htmlExporter.setParameter(JRHtmlExporterParameter.IMAGES_URI,"image?image=");
htmlExporter.exportReport();
}catch(JRException e){
e.printStackTrace();
}
