Sub Report ".jrxml"/ ".jasper"

[neozerabbit]

When using sub report is it possible (and how) to use sub report jxml file instead of ".jasper" ?

Hi,

The subreportExpression always expects a JasperReport object value. If you need to start from a jrxml file, you have to compile it first, to get a JasperReport object:

<subreportExpression class="net.sf.jasperreports.engine.JasperReport">
 <![CDATA[net.sf.jasperreports.engine.JasperCompileManager.compileReport("<path_to_jrxml_file_here>")]]>
</subreportExpression>

Hope this helps,
sanda

Thanks. It's interesting. It works if I put the complete absolute file path but no the "SUBREPORT_DIR" + xxxx.jrxml file.

I don't know why because there is no problem when I use the xxx.jasper file.

Could you post the jrxml source here?

Usually the subreport expression process with no problems the $P{} syntax.

Thank you,

Your solution gave me an idea

In Java :  I load, compile a report and put it as parameter

......

InputStream inputStreamErrors = Thread.currentThread().getContextClassLoader().getResourceAsStream("Ib-Daily-Errors-Report.jrxml");
JasperReport errorsReport = JasperCompileManager.compileReport(inputStreamErrors);

.......

Map<String, Object> ibReportParam = new HashMap<String, Object>();

ibReportParam.put("errorsReport", errorsReport);

 

In Main report : 

set a parameter "errorsReport" as "net.sf.jasperreports.engine.JasperReport"

Do not check "Use as prompt"

Set sub report as

<subreport>
                <reportElement stretchType="RelativeToBandHeight" isPrintRepeatedValues="false" x="0" y="0" width="2530" height="100"/>
                <dataSourceExpression><![CDATA[$P{ib-report-errors-dataSource}]]></dataSourceExpression>
                <subreportExpression class="net.sf.jasperreports.engine.JasperReport">

                           <![CDATA[$P{errorsReport}]]>

                </subreportExpression>
</subreport>
