nullpx in jasperreport html view

Question

I need a report in my web application.For that i have designed a jrxml in iReport. I had made a blank A4 template. And i had complied that file and then put that jrxml file to my classpath. But when i select that html view, an 'X' image is diplaying in that page. In view source, that element is given as

<td><img alt="" src="nullpx" style="width: 46px; height: 1px;"/></td>

My jsxml file is like

<?xml version="1.0" encoding="UTF-8"?>
<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="myreport" pageWidth="612" pageHeight="792" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20" uuid="a086f896-d28c-413e-8acc-416ff16d190a">

</jasperReport>

Is there anyway that i can use html with out any images in htmlpage..

Answer 1

Set JRHtmlExporterParameter.IS_USING_IMAGES_TO_ALIGN property to 'false'

Answer 2

Set the exporterParameter named net.sf.jasperreports.engine.export.JRHtmlExporterParameter.IS_USING_IMAGES_TO_ALIGN to false:

For example:

<bean id="multiViewReport" class="org.springframework.web.servlet.view.jasperreports.JasperReportsMultiFormatView">
    <property name="url" value="classpath:someJasperReport.jrxml" />
    <!-- Set the ModelMap attribute "reportDataKey" to the JRDataSourceProvider -->
    <property name="reportDataKey" value="reportDSProvider" /> 
    <property name="exporterParameters">
         <map>
             <entry
                key="net.sf.jasperreports.engine.export.JRHtmlExporterParameter.IS_USING_IMAGES_TO_ALIGN">
                <value>false</value>
            </entry>
         </map>
     </property>
</bean>

and my controller method looks like this:

@RequestMapping(value = "/report/{format}", method = RequestMethod.GET)
public String printWelcome(ModelMap model, @PathVariable(value = "format") String format) {
    JRDataSourceProvider jrDataSourceProvider = .....;
    model.addAttribute("format", format);
    model.addAttribute("reportDSProvider", jrDataSourceProvider);
    return "multiViewReport";
}

This controller allows me to produce different report formats by just appending the format type to the base url.

For example: http://yourhost.com:8080/springmvc-jasperreports/report/pdf

PS: I tested this with spring-webmvc 3.2.1.RELEASE and jasperreports 4.5.1.
