I'm sending you a part of my code:
my web.xml contains:
servlet
servlet-nameImageServlet/servlet-name
servlet-class
net.sf.jasperreports.j2ee.servlets.ImageServlet
/servlet-class
/servlet
servlet-mapping
servlet-nameImageServlet/servlet-name
url-pattern/reportImage/url-pattern
/servlet-mapping
---
and my code is as following:
JasperReport jasperReport = getCompiledReport(reportPath);
JasperPrint jPrint =
JasperFillManager.fillReport(jasperReport, getGraphParameters(), ds);
request.getSession()
.setAttribute(ImageServlet.DEFAULT_JASPER_PRINT_SESSION_ATTRIBUTE, jPrint);
ByteArrayOutputStream out = new
ByteArrayOutputStream();
String imgExtension =
String.valueOf(randomImageExtensionGenerator.nextInt());
exporter = new JRHtmlExporter();
exporter.setParameter(JRExporterParameter.JASPER_PRINT, jPrint);
exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, out);
exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI,
request.getContextPath()
+ /reportImage?rnd= + imgExtension
+ image=);
exporter.exportReport();
i add random parameters to the end of the image path in order to renew the
browser cache for every request.
I hope this helps.

Hi!!
I generated a file jrxml using the iReport 3.0.0 and when I try to print
the report in a servlet the html doesn't show the images of a 3D Chart,
This is the code in my servlet
JasperReport jasperReport =
JasperCompileManager.compileReport(jrxmlPath);
JasperPrint jasperPrint =
JasperFillManager.fillReport(jasperReport, parameters, getConnection());
JRHtmlExporter exporter = new JRHtmlExporter();
request.getSession().setAttribute(ImageServlet.DEFAULT_JASPER_PRINT_SESSION_ATTRIBUTE,
jasperPrint);
exporter.setParameter(JRExporterParameter.JASPER_PRINT,
jasperPrint);
exporter.setParameter(JRExporterParameter.OUTPUT_WRITER, out);
exporter.setParameter(JRHtmlExporterParameter.IS_OUTPUT_IMAGES_TO_DIR,Boolean.FALSE);
exporter.exportReport();
My project uses the library 3.1.3
Thanks
Esau
