Look in the subreport example from jasper reports download. In the .java file you'll see an entry like this:
JasperReport subreport = (JasperReport)JRLoader.loadObjectFromLocation("ProductReport.jasper");
//Preparing parameters
Map parameters = new HashMap();
parameters.put("ProductsSubreport", subreport);
Then in you .jrxml file there will be a section like this. iReport will create this. In iReport the parameter class is net.sf.jasperreports.engine.JasperReport. The subReportParameter Name is the parameter where the data link is passed. This part is from my report since it include the parameter name for the data link between the two. (that and I happened to have it opened :).
<band height="27">
<subreport>
<reportElement x="0" y="0" width="572" height="25"/>
<subreportParameter name="OPPTSOL_LINK">
<subreportParameterExpression><![CDATA[$F{oppt_id}]]></subreportParameterExpression>
</subreportParameter>
<connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]></connectionExpression>
<subreportExpression class="java.lang.String"><![CDATA["SolutionOverview_Solution1.jasper"]]></subreportExpression>
</subreport>
</band>

But this code we can use in our Master.jrxml while designing with ireport or jrxml designing tool.
In fact I want to write this code through java code because master report I am designing by the use of JasperDesign API.
So further I am requesting to Please Provide the Java Code for Adding The sub report (jasper Or jrxml) file .

Hi,
Perhaps it's a classpath matter here. When you are running the report from java, the relative path "./" does not point to the same current directory as when running the report from iReport.
Try to see which is the current directory when running from java, and set the corect path to the netIncomeStatement_subreport0.jasper object.
Hope this helps,

I think i had an answer for this. But it is some sort temp solution.
Basically the fillManager is looking for the compiled object while jrxml is not compiled.
So in the SUBREPORT_DIR should look like:
class="net.sf.jasperreports.engine.JasperReport" isforprompting="false" name="SUBREPORT_DIR"
and the subreportExpression in the subreport tag under main report should be the above SUBREPORT_DIR
for some reason i can not paste my code here, it looks like the HTML editor is messed up here. I am using IE10
