Pls help with dataSourceExpression

[fatsy]

Hallo all,

 

I have a question on how to declare dataSourceExpression in JRBeanCollectionDataSource.

For example with Xml xpath I'll declare dataSourceExpression as following

((net.sf.jasperreports.engine.data.JRXmlDataSource)$P{REPORT_DATA_SOURCE}).dataSource("/UseCaseGroup/UseCaseGroup/UseCase[@title="+$F{title}+&quot]/AlternativeScenario/Step")

What I would like to know is how to declare the part([@title="+$F{title}+&quot]) in JRXmlDataSource.

I did declare my dataSourceExpression as following new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{RG}) but the problem is that it will only be displayed once not for all objects.

I think when using for all title them all objects will be displayed as in xml.

 

Help will be really apreciated.I stuck for days on this problem.

Thanks in advance.

 

Regards

Fatma
