Error in Jasper Report

Question

I am using jasper report to generate pdf file from my database.

Here is my code..

ReportGenerator.java

conn = DriverManager.getConnection(
        "jdbc:oracle:thin:@localhost:SID","username","password");
System.out.println("Loading Report Designs");
InputStream input = new FileInputStream(new File("jrxml/EmployeeReport.jrxml"));
JasperDesign jasperDesign = JRXmlLoader.load(input);

System.out.println("Compiling Report Designs");
JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);

System.out.println("Creating JasperPrint Object");
Map<String, String> parameters = new HashMap<String, String>();
parameters.put("ReportTitle", "PDF JasperReport");

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,null,conn);

//Exporting the report
OutputStream output = new FileOutputStream(new File("report/EmployeeReport.pdf"));

JasperExportManager.exportReportToPdfStream(jasperPrint, output);

System.out.println("Report Generation Complete");
conn.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (JRException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {

}
}

public static void main(String[] args) {
new ReportGenerator().generateReport();
}
}

I have added jasperreport.dtd file in my project. Please help me to resolve this issue.

Answer 1

ClassLoader loader = getClass().getClassLoader();

InputStream reportName = new FileInputStream(newFile(
            loader.getResource("reportes/ReporteCalendarizado.jrxml").getFile()));
            JasperDesign jasperDesign = JRXmlLoader.load(reportName);

Answer 2

Sometimes errors are caused because of spaces in paths, so if you check manually that the jasperreport.dtd file exists in the mentioned path then try to use an eclipse workspace without spaces in it (i.e. change Eclipse Projects to EclipseProjects)
