Display PDF in IE from byte array using Servlet

[Sam Gehouse]

I am using a Servelt to display byte array of PDF into IE browser. Correct number of bytes are returned from existing PDF. Any help with code will be appreciated. I am using code below:

public void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {

resp.setContentType("application/pdf");
resp.setHeader("Expires", "0");
resp.setHeader("Cache-Control","must-revalidate, post-check=0,
pre-check=0");
resp.setHeader("Pragma", "public");

resp.setHeader("Pragma", "no-cache"); //HTTP 1.0
resp.setDateHeader("Expires", 0); //prevents caching at the proxy server
resp.setHeader("Cache-Control", "no-cache"); //HTTP 1.1
resp.setHeader("Cache-Control", "max-age=0");

resp.setHeader("Content-disposition", "inline; filename=stuff.pdf");

byte[] inputBytes = MyTest.getBytesFromFile(new File("C:\\TR.pdf"));
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

if(inputBytes !=null){
outputStream.write(inputBytes);
}
outputStream.flush();
}

File file = new File("Filepath here");
response.setHeader("content-disposition", "inline" );
response.setContentType("application/pdf");       
response.setContentLength((int)file.length());
 
ServletOutputStream out = response.getOutputStream();
FileInputStream stream = new FileInputStream(file);
BufferedInputStream bis = new BufferedInputStream(stream);
BufferedOutputStream bos = new BufferedOutputStream(out);
 
byte[] buff = new byte[2048];
int bytesRead;
 
while(-1 != (bytesRead = bis.read(buff, 0, buff.length))) 
{
bos.write(buff, 0, bytesRead);
}
bis.close();
stream.close();
bos.close();
out.close();

I only get Base64 encoded String that makes up PDF. I do not get the PDF itself as argument. So, my input argument is String. I decode that String into byte array.

So, my goal is to convert byte array back to PDF for display purpose.

Any help with sample code?

try:

import sun.misc.*;
...
...
new BASE64Decoder().decodeBuffer(fileinputstream, servletoutstream);

Note that Sun doesn't recommend to use any classes from misc. However if your app isn't going to last forever, then you can use the package.
