I can´t open a .pdf in my browser by Java

I´m trying to open a pdf that I have created using iText library in my browser, but it fails. This is the code I´m using to send to browser

    File file = new File(path);

    try{
        //InputStream stream=blob.getBinaryStream();
        InputStream streamEntrada = new FileInputStream(file);
        //ServletOutputStream fileOutputStream = response.getOutputStream();
        PrintWriter print = response.getWriter();

        int ibit = 256;
        while ((ibit) >= 0)
        {
            ibit = streamEntrada.read();
            print.write(ibit);
         }

        response.setContentType("application/text");
        response.setHeader("Content-Disposition",  "attachment;filename="+name);
        response.setHeader("Pragma", "cache");
        response.setHeader("Cache-control", "private, max-age=0");
        streamEntrada.close();
        print.close();

        return null;
    }
    catch(Exception e){

        return null;
    }
}

I tried with FileOutputStream but isn´t works开发者_如何学Python. I´m desperate.

Thank you.

Now, I´m trying this way, but it doesn´t work:

public class MovilInfoAction extends DownloadAction{

protected StreamInfo getStreamInfo(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {

    //Here the creation of the PDF

    //Storing data
    PdfData dPdf = pdf.drawPDF(terminal);

    String path = dPdf.getPath();//Path
    String name = dPdf.getName()+".pdf";//Pdf´s name
    String contentType = "application/pdf";//ContentType

    response.setContentType(contentType);
    response.setHeader("Content-Disposition","attachment; filename="+name);
    response.setHeader("Cache-control", "private, max-age=0");
    response.setHeader("Content-Disposition",  "inline"); 

    File file = new File(path);
    byte[] pdfBytes = es.vodafone.framework.utils.Utils.getBytesFromFile(file);

    return new ByteArrayStreamInfo(contentType, pdfBytes);
}

protected class ByteArrayStreamInfo implements StreamInfo {

    protected String contentType;
    protected byte[] bytes;

    public ByteArrayStreamInfo(String contentType, byte[] bytes) {
        this.contentType = contentType;
        this.bytes = bytes;
    }

    public String getContentType() {
        return contentType;
    }

    public InputStream getInputStream() throws IOException {
        return new ByteArrayInputStream(bytes);
    }
}

}

You specify the mimetype as application/text, when it should be application/pdf.

You should set the Header and ContentType before you write the data. And set the Content Type to application/pdf.

change

 response.setContentType("application/text");

to

response.setContentType("application/pdf");

and if you want your pdf to open in browser then make following change

response.setHeader("Content-Disposition",  "inline");

Put the filename in double quote "

response.setHeader("Content-Disposition","attachment; filename=\"" + attachmentName + "\"");

Android Default Browser requires GET Request. It does not understand POST Request and hence cannot download the attachment. You can send a GET request as by sending GET request, it resolved my problem. Android browser generates a GET request on its own and sends it back to server. The response received after second request will be considered final by the browser even if GET request is sent on first time by the servlet.
