java - Jasper Report : Document root element "jasperReport", must match DOCTYPE root "null"

Question

I have designed jasper report using iReport version (4.7.1). Through iReport it works fine. When I called from java servlet, I get an error:

Error : `Document root element "jasperReport", must match DOCTYPE root "null".`

net.sf.jasperreports.engine.JRException: Document root element "jasperReport", 
must match DOCTYPE root "null".

Answer 1

Assuming that the jrxml file has been added to your jar file, you should load it like this:

InputStream is = ReportServlet.class.getResourceAsStream(themeDesignName);
jasperDesign = JRXmlLoader.load(is);
