[iText-questions] Streaming PDFs

[Ben Sinclair]

This isn't exactly an iText-specific question, but so far nobody seems to 
know the answer.

I create PDFs using iText and save them to files, then I want to stream 
them to the browser and open using the Acrobat plugin. This works just fine 
in IE, but in Mozilla 1.5.2 and Firebird 0.6 the Acrobat splash screen 
appears, but no PDF ever loads. I can view source in Firebird and see that 
the PDF looks valid. If I open the file manually from the server, it works, 
so I know the PDF is good.

Has anyone sucessfully streamed PDFs to Mozilla or Firebird?

Here is how I'm currently streaming it:

/**
 * Wait action
 */
package ben.actions;

import org.enhydra.xml.io.DOMFormatter;
import ben.DocumentGenerator;
import ben.bom.Pak;
import ben.html.WaitHTML;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.RandomAccessFile;
public class WaitAction extends Action {

        public static String KEY = "Wait";
        private String clientDir;
        public void execute(HttpServletRequest req, HttpServletResponse 
res) throws Exception {

                WaitHTML html = new WaitHTML();

                Pak pak = (Pak)req.getSession().getAttribute("package");
                addHeaderFooter(html, pak, KEY);
                DocumentGenerator dg = 
(DocumentGenerator)req.getSession().getAttribute("dg");

                if (dg.notDone()) { // Rendering not complete... Wait some 
more
                        new DOMFormatter().write(html, res.getWriter());
                        return;
                }

                // Rendering complete, stream file to user

                System.out.println("Streaming document: " + dg.getFilename());

                res.setContentType("application/pdf");

                RandomAccessFile in = new 
RandomAccessFile(dg.getFilename(), "r");
                ByteArrayOutputStream ba = new ByteArrayOutputStream();

                javax.servlet.ServletOutputStream out = res.getOutputStream();
                res.setHeader("Content-disposition", "inline; 
filename=temp.pdf");
                res.setContentLength((int)new 
File(dg.getFilename()).length());
                byte[] buf = new byte[100];

                int i = in.read(buf);
                while (i != -1) {
                        ba.write(buf, 0, i);
                        i = in.read(buf);
                }
                in.close();

                ba.writeTo(out);
                out.flush();
        }

}
