How to pass paremeters in subreports?

[ikaaki]

Hi,

 

I'm using xml file as datasource.

 

A.jrxml is the parent report and B.jrxml is the subreport. I left blank for the parameters map expression, $P{REPORT_CONNECTION} for Connection/Data source Expression, and add two subreport parameters. But I don't know how to pass the parameters in the subreport.

 

There are some documents for the subreport, but they always take SQL query as examples.

In the case of SQL query, we use "select * from xxx where abc=$P{Name_Parameter}".

But for the xml datasource, anyone knows how to write an expression for passing parameters?

I think it will be something like ($F{id}==$P{id})?$F{refs_id}:"N/A"

 

Thanks in avance.

Hi,

 

The /demo/samples/xmldatasource folder in the JR distribution package contains a sample with an XML data source and subreports. I think it is what you are looking for.

 

Thanks,
