Your code works well, it's creating an PDF with the PDF-Standard 1.4 and i assume a length of 216 characters.

But not the sender is the problem.

The receiver (aras) does not understand what is produced by:

        HttpContext.Current.Response.ContentType = "application/octet-stream";
        HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=Datatable.pdf");
        HttpContext.Current.Response.Clear();
        HttpContext.Current.Response.BinaryWrite(mStream.ToArray());
        HttpContext.Current.Response.End();

This does not work, as the aras client expects a SOAP-Message, not a PDF.

You need another way to transfer the file.

Hi,

I tried small piece of sample code below. But still its not creating .PDF file. But same code runs in C# application.

Document myDocument = new Document(PageSize.A4);
PdfWriter.GetInstance(myDocument, new System.IO.FileStream(@"D:abc.pdf", FileMode.Create));
myDocument.Open();
myDocument.Add(new Paragraph("First Pdf File using iText"));
 

Even this is not working. Can you suggest any other method.

Regards,
