Applet + Serialized Object + PDF == ??

Question

I have an applet that serializes a transport bean to a servlet on tomcat, based on the contents of the bean, the servlet makes a PDF that I want to display on the browser.
I had thought that if I simply set the response MIME type and return the binary data, the browser would know what to do. Silly me, but I forgot that in this case the applet is the one in control, not the browser. The browser screen just sits there. At least this is what I am guessing...
Here is the code that I use to send the serialized object :
    public InputStream sendPostMessage (Properties args) throws IOException
        String argString = "";  // default
        if (args != null)
            argString = toEncodedString (args);  // notice no "?"
        URLConnection con = servlet.openConnection ();
        // Prepare for both input and output
        con.setDoInput (true);
        con.setDoOutput (true);
        // Turn off caching
        con.setUseCaches (false);
        // Work around a Netscape bug
        con.setRequestProperty ("Content-Type", "application/x-www-form-urlencoded");
        // Send headers
        sendHeaders (con);
        // Write the arguments as post data
        DataOutputStream out = new DataOutputStream (con.getOutputStream ());
        out.writeBytes (argString);
        out.flush ();
        out.close ();
        return con.getInputStream ();
    }Here is the question...
Given the fact that I am serializing an object to the servlet, and that the applet is sitting there.. Is there a way to make the Browser display the PDF?
I have my doubts about ShowDocument(URL) as I am generating the PDF on the fly without using a temporary file. (Jasper reports) In addition, aren't there sandbox issues on the server side for creating a file?
Any other ideas?

Answer 1

I think that IS what I will have to do but, I was hoping to use the PDF binary stream coming directly from the servlet.
I guess this isn't possible?
