Generates the report as HTML and setups everything for a clean response (serving images as well). You have to declare JasperReport servlet in web.xml (net.sf.jasperreports.j2ee.servlets.ImageServlet)

Web XML must be configured somehow like this:

<servlet>
<servlet-name>image</servlet-name>
<servlet-class>net.sf.jasperreports.j2ee.servlets.ImageServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>image</servlet-name>
<url-pattern>/reports/image</url-pattern>
</servlet-mapping>


Parameters:

request -

response -

imageServletUrl - the URI to reach net.sf.jasperreports.j2ee.servlets.ImageServlet servlet (in example it would be "reports/image")

dynamicReport -

layoutManager -

ds -

parameters - Parameters for the DynamicReport

exporterParams - Extra parameters for JasperReport's HTML exporter (HTMLJRHtmlExporter)

Throws:

net.sf.jasperreports.engine.JRException

java.io.IOException
