public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
response.setContentType(“application/jar”);
ServletContext ctx = getServletContext();
InputStream is = ctx.getResourceAsStream(“bookCode.jar”);
int read = 0;
byte[] bytes = new byte[1024];
OutputStream os = response.getOutputStream();
while ((read = is.read(bytes)) != -1) {
os.write(bytes, 0, read);
}
RequestDispatcher view = request.getRequestDispatcher(“result.jsp”);
view.forward(request, response);
os.close();
}
i can't understand why i have an error with this. because i know calling os.flush() before dispatching the request will give me an IllegalStateException. but i don' know if write commits the response too.

The problem isn't that you are writing to the servlet's output stream. The problem is that you are forwarding to a JSP after you finish. Don't do that. You're sending a copy of a jar file as the response; forwarding to a JSP just adds on some HTML at the end which would only make a mess anyway. Don't do that.
