Displaying pdf from file system in OA framework pages

Question

Hi,
If anyone could help me with this I would be very grateful.
We have a number of pdfs containing sensitive information, held on our Unix file system in directories not publicly available.
I want to create an OA framework page which takes the name of a pdf as a parameter and displays the content of that pdf on the user's browser. I cannot simply do a redirect because the pdfs are not publicly available.
I've found some sample java code that allows you to set InputStream and OutputStream and read the content of the file. However, I cannot see how to redirect the output stream to the browser. Of course, this may be entirely the wrong approach.
Can anyone suggest anything or point me to some documentation that might help?
Many thanks,
Mike Thorn.

Hi Shiv,
Thanks for responding. I'm not sure whether I've explained my problem properly, so I've included a code snipet below.
I've got my head around how to stream the contents of a file to an output string but cannot see how to bolt this into the controller region for an OA framework page. In the code below, you'll see I have a dofile which reads from my D: drive and streams to the System.out. I'm calling this from the processRequest for the page controller but do not understand how to get the output stream into the OAHTMLWebBean (my inclusion of Google works just fine).
All this Java is rather new to me I'm afraid.
public static void dofile()
try{
OutputStream outStream = System.out;
String fileName= (String)"index.htm";
String filePath = "D:\\Jdeveloper\\jdevdoc\\";
File f = new File(filePath, fileName);
String fileType = fileName.substring(fileName.indexOf(".")+1,fileName.length());
byte[] buf = new byte[8192];
FileInputStream inStream = new FileInputStream(f);
int sizeRead = 0;
while ((sizeRead = inStream.read(buf, 0, buf.length)) > 0) {
outStream.write(buf, 0, sizeRead);
inStream.close();
outStream.close();
     catch (Exception e) {
          System.err.println(e);
          System.err.println("dofile error");
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
dofile(); //but how do I egt the output to the OAHTMLWebBean?
// the following works fine to include Google
OAHTMLWebBean outRegion = (OAHTMLWebBean)createWebBean(pageContext, HTML_WEB_BEAN, null, "IFRAME");
outRegion.setHTMLAttributeValue("src","http://www.google.co.uk");
outRegion.setHTMLAttributeValue("width", "100%");
outRegion.setHTMLAttributeValue("height", "60%");
outRegion.setHTMLAttributeValue("title","My title");
outRegion.setHTMLAttributeValue("name", "My name");
pageContext.getPageLayoutBean().addIndexedChild(outRegion);
Many thanks again for any help you can offer this Java virgin,
Mike Thorn
