stream a string to a browser from applet

I have a java applet that gets a string containing html.  I need to stream this to a new browser window, which means using the getAppletContext() method.  At the moment, I write this string to a file on the pc (the applet is signed and is being allowed to do this), creating a new browser window with the getAppletContext, and giving it a URL of file:///c:/temp/myfile.html.  I would much prefer to stream the string to the browser, but I am totally stumped on how to do this.  

Here's what I'm doing now:

try
 {
     BufferedWriter out = new BufferedWriter(new FileWriter(sFileName));
     out.write(mo_Ap.getReport());
     out.close();
 }
 catch (IOException ie)
 {
   System.out.println(ie.getMessage());
 }

 try
 {
   AppletContext browser = getAppletContext();
   browser.showDocument(new URL("file:///" + sFileName), "_blank");

 }
 catch(MalformedURLException ue)
 {
   System.out.println(ue.getMessage());
 }

Any help appreciated.
