Now, how do I write the java code with XML data sources for Jasper report with sub-report? I tried this:

JasperPrint print = new JasperPrint();
JRPdfExporter exporter = new JRPdfExporter();
JasperDesign design, design1;
JasperReport report, report1;
JasperReport jasperReport;
JasperDesign jd1;


jd1 = JRXmlLoader.load("C:/Users/bferrao/Desktop/jasper/TransactionReport_subreport1.jrxml");
jasperReport = JasperCompileManager.compileReport(jd1);

Map parameters = new HashMap();
parameters.put("Subreport_1", jasperReport);

design = JRXmlLoader.load("C:/Users/bferrao/Desktop/jasper/TransactionReport_subreport2.jrxml");
report = JasperCompileManager.compileReport(design);
parameters.put("Subreport_2", report);

Document document = JRXmlUtils.parse(new File("C:/Users/bferrao/Desktop/jasper/TransactionReport.xml"));
parameters.put(JRXPathQueryExecuterFactory.PARAMETER_XML_DATA_DOCUMENT, document);

JRXmlDataSource jrxmlds = new JRXmlDataSource(new File("C:/Users/bferrao/Desktop/jasper/TransactionReport.xml"), "/Report");
design1 = JRXmlLoader.load("C:/Users/bferrao/Desktop/jasper/TransactionReport.jrxml");
report1 = JasperCompileManager.compileReport(design1);
JasperFillManager.fillReportToFile(report1, "C:/Users/bferrao/Desktop/jasper/master_report.jrprint", parameters, jrxmlds);

exporter.setParameter(JRExporterParameter.JASPER_PRINT, print);
exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, "D:\\temp\\Report3.pdf");
exporter.exportReport();

Looking at your stackoverflow I have modified my main report and java building of report. How do I pass the XML datasource? I'm still getting blank report.

Just for information, in general it is better if you do not modify your initial question because the answer(s) can be totally wrong after your changes. If you want to give an update it is better to comment here (or on the answer) than changing the inital code. Otherwise (but for shorter question) you can add an "UPDATE:" section. – рüффп

In your Java code you are adding the two subReport as parameters Subreport_1 and Subreport_2 but the master report declares only a parameter named "SUBREPORT_DIR".

I did something similar than your Java code (summarized): 

   // first compile the sub reports
   jasperReport = JasperCompileManager.compileReport(jd1);
   jasperReport = JasperCompileManager.compileReport(jd1);
   report = JasperCompileManager.compileReport(design);

   // then add the compiled reports to your parameters
   Map parameters = new HashMap();
   parameters.put("Subreport_1", jasperReport);
   parameters.put("Subreport_2", report);

   // and finally send the sub-reports to the main report as parameters
   JasperFillManager.fillReportToFile(report1, "D:/temp/master_report.jrprint", parameters, jrxmlds);

You have to declare the subreport as parameter like this in the master jrxml: 

<parameter name="Subreport_1" class="java.lang.Object"/>
<parameter name="Subreport_2" class="java.lang.Object"/>

...

<subreport runToBottom="false">
    <reportElement uuid="ce3bf2a2-9131-4d75-800b-25d4a71791c3" 
         positionType="Float"    isPrintRepeatedValues="false" 
         x="0" y="179" width="468" height="28" isRemoveLineWhenBlank="true"/>
    <subreportParameter name="XML_DATA_DOCUMENT">
        <subreportParameterExpression><![CDATA[$P{XML_DATA_DOCUMENT}]]></subreportParameterExpression>
    </subreportParameter>
    <subreportExpression><![CDATA[$P{Subreport_1}]]></subreportExpression>
</subreport>

and the following parameter can be removed as it seems not used in your code:

<parameter name="SUBREPORT_DIR" class="java.lang.String" isForPrompting="false">
        <defaultValueExpression><![CDATA["C:\\Users\\bferrao\\Desktop\\jasper\\"]]></defaultValueExpression>
</parameter>

Another thing you have to be careful is the datasource visibility in the subreport.
