I'm sending you a part of my code:
my web.xml contains:
<servlet>
<servlet-name>ImageServlet</servlet-name>
<servlet-class>
net.sf.jasperreports.j2ee.servlets.ImageServlet
</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ImageServlet</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.
Regards
