JRException Resource not found at when there is a subreport in Jasper Report

Question

I made a jasper report that includes a subreport using JasperSoft Studio. When i preview it in the studio, it works fine. But when i add it into my java fx project, i have to send the subreport as a parameter to the main report right?

When i do that i keep on getting an error saying that the subreport resource not found. I dont think there is any spelling errors because i hv tried this with almost all the reports that includes subreports.. still keep on getting that error..

These are the things i tried 1. compiled the report again using the jaspersoft studio and includeded them again in the project.. 2. included the jrxml file into the project and compiled it with the Compile Manager.. 3. i read some tutorials and questions saying that to put the expression to the subreport element in the main report as

$P{SUBREPORT_DIR} + "subreport_2.jasper"

but i still keep on getting the same error and i dont know what i am doing wrong Below is my code

method in application used to view the report

@FXML
    public void btnMarkingSchemeClicked(ActionEvent actionEvent) {
        try {

//            JasperReport compiledReport = (JasperReport) JRLoader.loadObject(ViewAssignmentsController.class.getResourceAsStream("/edu/ijse/gdse41/ams/reports/MarkingScheme.jasper"));
            JasperReport compiledReport = JasperCompileManager.compileReport(ViewAssignmentsController.class.getResourceAsStream("/edu/ijse/gdse41/ams/reports/MarkingScheme.jrxml"));
            HashMap<String, Object> parameters = new HashMap<>();
            parameters.put("assignID", aid);
            parameters.put("course", cmbCourse.getSelectionModel().getSelectedItem().toString());
            parameters.put("subject", cmbSub.getSelectionModel().getSelectedItem().toString());
            parameters.put("semester", cmbSem.getSelectionModel().getSelectedItem().toString());
            parameters.put("assign", ctrlAssign.search(aid).getAssignName());
//            JasperReport subReport = (JasperReport) JRLoader.loadObject(ViewAssignmentsController.class.getResourceAsStream("/edu/ijse/gdse41/ams/reports/Answers.jasper"));
            JasperReport subReport = JasperCompileManager.compileReport(ViewAssignmentsController.class.getResourceAsStream("/edu/ijse/gdse41/ams/reports/Answers.jrxml"));
            parameters.put("subReport", subReport);
            JasperPrint fillReport = JasperFillManager.fillReport(compiledReport, parameters, ConnectionFactory.getInstance().getConnection());
            JasperViewer.viewReport(fillReport, false);

        } catch (JRException | SQLException | ClassNotFoundException ex) {
            Logger.getLogger(ViewAssignmentsController.class.getName()).log(Level.SEVERE, null, ex);
        }

    }

Answer 1

It is because even though you have created a parameter called "subReport" it hasn't been used anywhere.

           <subreport>
            <reportElement x="100" y="20" width="440" height="20" uuid="72f8c7c2-82ca-48d3-bb89-d5bb4846e1bc"/>
            <subreportParameter name="qid">
                <subreportParameterExpression><![CDATA[$F{qid}]]></subreportParameterExpression>
            </subreportParameter>
            <connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]></connectionExpression>
            <subreportExpression><![CDATA["Answers.jasper"]]></subreportExpression>
        </subreport>

See? It is still "Answers.jasper" there in the main report. That is why it works fine in Jasper Studio. Let's change it to,

           <subreport>
            <reportElement x="100" y="20" width="440" height="20" uuid="72f8c7c2-82ca-48d3-bb89-d5bb4846e1bc"/>
