I keep getting this error using Eclipse and Tomcat.  I went over my
code a 100 times and I do not close the output stream or do I make more
than one call here is my code.

I call the method( HttpServletRequest req, HttpServletResponse resp)
then I do a
RequestDispatcher _view = req.getRequestDispatcher("/errorPage.jsp") ;
// return to error
_view.forward(req,resp);
and I get the illegalstateExceptionerror

method( HttpServletRequest req, HttpServletResponse resp)
{

        try{
            // set approriuate data for returning a file ot type .csv
            resp.setContentType("application/vnd.ms-excel");
            resp.setContentLength((int) _outputFile.length());
            resp.setHeader("Content-Disposition","attachment; filename=\"" +
_outputFile.getName() + "\"");
            outStream = resp.getOutputStream();
                byte[] buf =  new byte[8192];
                FileInputStream inStream = new FileInputStream(_outputFile);
                int sizeRead = 0;
                // write to resp stream
                while((sizeRead = inStream.read(buf, 0 , buf.length)) > 0) {
                outStream.write(buf, 0 , buf.length);
            }

        }catch(Exception e) {System.out.println("ERROR");
e.printStackTrace();
        return false;
        }

        return true;
}

// Here is my forward
RequestDispatcher _view = req.getRequestDispatcher("/errorPage.jsp") ;
// return to error
_view.forward(req,resp);

I just can not forward to another page after writing, I did this same
code on a different m achine.
Thanks so much!!  I am dieing over here trying to figure thius forward
out!!!! using newest SDK.
