2004-03-14 22:47

Hi all,

 

Iam using the JRDataSource for my reporting, I passed the parameter from the master report to the subreport using subreport parameter, I don't know what kind of alteration i have to do in subreport with the passed parameter.

 

Please help me!! I need this urgently, give me some sample of code to be altered in subreport.

 

Thanks in advance

You don't need to alter anything in the subreport. the dataSourceExpression that you use (did you?) in the main report will pass the data source directly in to the $P{REPORT_DATASOURCE} default parameter in the subreport.

so... assuming you're using just one single JRDataSource, you'll have this in your main report

 

<subreport...>

...

<dataSourceExpression>

$P{REPORT_DATA_SOURCE}

</dataSourceExpression>

...

</subreport>

 

then in your subreport, you don't have to bother with any data source stuff, just make sure you have all the fields probably declared.
