How to use Variables in Xpath

[fatsy]

Hallo,

I have master report which has a variable declared in it.The subreport ist using its own data expression i.e (net.sf.jasperreports.engine.data.JRXmlDataSource)$P{REPORT_DATA_SOURCE}).dataSource("/UseCaseGroup/UseCaseGroup/UseCase[@id=$V{ID}]/MainScenario/Step")]]

But unfortunately the subreport part is blank.

So my question did I not correctly my XPath or what i'm I supposed to do to make them visible.

 

Any help or suggestion will be very appreciates

Thanks in advance

You need something like

Code:

<dataSourceExpression>
  ((net.sf.jasperreports.engine.data.JRXmlDataSource) $P{REPORT_DATA_SOURCE}).dataSource("/UseCaseGroup/UseCaseGroup/UseCase[@id='" + $V{ID} + "']/MainScenario/Step"«»)
</dataSourceExpression>

 

HTH,
