SubReport Filename as a Parameter

2003-10-08 10:49

Is it possibl to pass the name of a subreport file using a parameter? I'm trying the following (and a couple of different variations) without success. Or I should say, when I try to pass in the parameter I am getting an OutOfMemoryException. However, when I hard code the path, the report is generted correctly.

 

Here is the snippet from the xml definition:

parameter definition:

<parameter name="DIRECTORY" isForPrompting="false" class="java.lang.String"/>

 

subreport definition:

<subreport isUsingCache="true">

<reportElement

mode="Opaque"

x="1"

y="120"

width="543"

height="20"

forecolor="#000000"

backcolor="#FFFFFF"

positionType="Float"

isPrintRepeatedValues="true"

isRemoveLineWhenBlank="false"

isPrintInFirstWholeBand="false"

isPrintWhenDetailOverflows="false"/>

<dataSourceExpression><![CDATA[$F{items}]]></dataSourceExpression>

<subreportExpression class="java.lang.String"><![CDATA[$P{DIRECTORY}+"PackSlipItems.jasper"]]></subreportExpression>

</subreport>

 

Thanks,

Chris....

Yes. It is possible.

You can pass the sub report filename to the main report as an ordinary parametre. From the main report, instead of passing the sub report file name as string you can pass this parametre
