How to pass parameter to sub report in JasperReports?

I'm able to pass the parameter to master report but I'm not able pass parameter to its sub report.

Can any one give me the solution for it?

Try using iReport if you are not.

When viewing a report within iReport you can select the properties of the subreport within the main report.

In this there is an option in Subreport properties called Parameters. Using this you can pass parameters to your subreport.

• Select this and click the Add button.

• Then click the button right of the Value expression Box

• Next an option screen will pop up where you can select the parameter from the master report you want to pass.

If you want to do it via xml here's a quick example.

<subreport>
    <subreportParameter name="XML_ID">
        <subreportParameterExpression>
            <![CDATA[$P{MASTER_REPORT_PARAMETER}]]></subreportParameterExpression>
    </subreportParameter>
</subreport>
