Spring and Jasper Reports subreporting issue

[sudarshan_k]

I am trying to integrate jasper reports with our application. Spring is our main framework and use the Spring MVC for view processing. I have a particular issue with subreports as they don't seem to show up when I use a collection as my datasource. If I use a JDBC datasource the subreports show up on the screen. Here is how i have included the sub reports in my report view:

<subreport isUsingCache="true">
<reportElement
x="0"
y="0"
width="530"
height="20"
key="subreport-1"/>
<subreportExpression class="net.sf.jasperreports.engine.JasperReport">< ![CDATA[$P{headerView}]]></subreportExpression>
</subreport>


I have a parameter called headerView at the top.

I have a bean to display this as shown:


<bean id="accountSummaryView" class="org.springframework.web.servlet.view.jasper reports.JasperReportsMultiFormatView">
<property name="url" value="/WEB-INF/reports/classicRenameMod.jasper"></property>
<property name="reportDataKey" value="accountSummaryBeansList"/>
<property name="subReportUrls">
<map>
<entry key="headerView" value="/WEB-INF/reports/awardHeader.jasper"/>
</map>
</property>

</bean>

The subreport as of now just has a few static text fields with no datasource attached to it, but does not seem to show up in my view. Any help would be widely appreciated.
