Response Output as PDF

[Vishnu Prakash]

How to write the response output as PDF. I tried with the following code.

  
 
 try {
 String string = "Servlet Technology";
 int size = string.length();
 byte[] bite = string.getBytes();
 byte[] data = new byte[size]; // allocate byte array of right size
 ByteArrayInputStream byteStream = new ByteArrayInputStream(bite);
 int in = byteStream.read( data, 0, size ); // read into byte array
 
 byteStream.close();
 response.setContentType("application/pdf");
 
response.setHeader("Content-Disposition","inline; filename=architect.pdf");
response.setHeader("Cache-Control", "no-cache");
 response.setDateHeader("Expires", 0);
 response.setHeader("Pragma", "No-cache"); 
 
 OutputStream OutStream = response.getOutputStream();
 OutStream.write(data);
 OutStream.flush();
 OutStream.close();
 }catch(Exception e ){
 System.out.println(e);
 e.printStackTrace();
 }
 

There was no error (or) Exception in Tomcat server. But the FireFox browser is saying

File does bor begin with '%PDF--';

To send the response as a pdf, you would first need to generate a PDF.
Try a Google search for "Apache FOP" or "itext" to find some libraries for generating PDFs.

Itext is memmory centric. If memmory is a constraint FOP is a beeter choice.
iText is easy to configure and use. For bigger applications FOP is prefered.

Another tool is FDF toolkit. Which also have limitations.
