How to access a file from the source folder in Vaadin ?

I am developing an application where I need to print tickets for the customers. In order to do this, I have created a PDF template file and copied that file along with java source files. I have to access this template file and fill the template fields with new values and open a new PDF file in browser which will be printed.
But the problem is, I am not able to access this template file. I am using iText PDF API. I am trying to read the template file, but it gives an exception that, in the given path is not found as a File or Resource.
If I give the complete path it reads with no problem. But I am not able to read it with a reference path.

This is my code:
//String templatePath=VaadinService.getCurrent().getStaticFileLocation(VaadinService.getCurrentRequest()) + File.separator+ “psv-ticket-template.pdf”;

        //String templatePath=VaadinServlet.getCurrent().getServletConfig().getServletContext().getContextPath() + File.separator+ "psv-ticket-template.pdf";
        //String templatePath= "./psv-ticket-template.pdf";
        String templatePath=VaadinServletService.getCurrent().getBaseDirectory().getAbsoluteFile() + File.separator+"member"+File.separator+"psv-ticket-template.pdf";

        PdfReader reader = new PdfReader([b]

[/b]); //This is where I am getting Exception
ByteArrayOutputStream baos = new ByteArrayOutputStream();
PdfStamper stamper = new PdfStamper(reader, baos);

        reader = new PdfReader(baos.toByteArray());
        Document document = new Document(reader.getPageSizeWithRotation(1));
        PdfCopy writer = new PdfCopy(document,new FileOutputStream("psv_ticket.pdf"));;

        PushbuttonField pushbuttonField=null;
        for(BookingDetail bookingDetail:bookingHeader.getBookingDetailSet()){
            reader = new PdfReader(templatePath);
            baos = new ByteArrayOutputStream();
        //.................and so on.

If it is not possible to store a file like that, then where can I store it?
Someone please help me,


To get a file that you have in the source folder, use the Context Class Loader:


The file is in the source root.
