Pass Parameter Map to Subreport
2002-08-23 09:03
Hi all-

I know its possible to pass the entire set of parameters to the subreport - it was mentioned off-handedly on a post somewhere.

Can anyone tell me how to do this? Its not in the current docs. . .

Thanks,

Eric Everman

Well, I don't have a current sample - I have used this, but have since forgotten which project it was on. But, its very simple, below is an (untested) snippet for a subreport. Also check out the current docs for the subreport
http://jasperreports.sourceforge.net/quick.reference.html#subreport


<subreport isUsingCache="true">
<reportElement x="5" y="25" width="240" height="28" backcolor="#DDFFFF"/>
<parametersMapExpression>
REPORT_PARAMETERS_MAP
<parametersMapExpression>
<subreportParameter name="org_id">
<subreportParameterExpression>
$F{id}
</subreportParameterExpression>
</subreportParameter>
<connectionExpression>
$P{REPORT_CONNECTION}
</connectionExpression>
<subreportExpression class="java.lang.String">
"SubReportName.jasper"
</subreportExpression>
</subreport>

Replace "REPORT_PARAMETERS_MAP" with "$P{REPORT_PARAMETERS_MAP}"
