service() method called Twice when using creating response with MIME type application/x-shockwave-flash

[Andrew Milkowski]

Using Apache Tomcat/4.1.12 deployment, following sample code in the servlet
used to demonstrate this behavior

public void service (HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {

        final BufferedOutputStream bufferedOutputStream = new
BufferedOutputStream(response.getOutputStream(), 2048);

        ..
        ..
        ..

        response.setContentType("application/x-shockwave-flash");

        schart.encodeAsSWF(bufferedOutputStream);  // (schart here is a carting
package that encodes swf file into the OutputStream)


        response.setHeader("Expires", "-1");
        response.setHeader("nPragma", "no-cache");

        bufferedOutputStream.flush();
        bufferedOutputStream.close();

        response.flushBuffer();
}

in the above service method gets called twice, before rendering browser
output with the Flash MIME content!

Did anyone here had a similar experience? (maybe not necessarily with a
application/x-shockwave-flash) where service
method is called twice before completing response..

Any suggestions/solutions greatly appreciated!
