Downloading PDF files - Does not open file in browser

[2devnull]

clicking on a link for a PDF file just opens a blank page on the browser. If I save the file to a directory and then open it, the file opens without any problem. The exact code works correct outside of Spring framework using a plain servet. Any ideas what needs to change to make it work in Spring?

Here is the code:

public ModelAndView binitemHandler(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		String repId = RequestUtils.getStringParameter(request, "RepID", "");
		BinaryItem binitem = null;
		ModelAndView mav = null;
		String ext = "";

		
			binitem = (BinaryItem) myFacade.getBinItem(repId);

			fileName = binitem.getFilename();
			logger.debug("Filename is: "+fileName);
			if (fileName != null) {
				int dot = fileName.lastIndexOf('.');
				ext = (dot > 0) ? fileName.substring(dot) : "txt";
				logger.debug("Extension is: "+ext);
			}
			response.setContentType(mapFileToMime(ext));
			logger.debug("Extension is setContentType: "+mapFileToMime(ext));
			response.setHeader("Content-disposition", "inline; filename=" + fileName);
			FileCopyUtils.copy(binitem.getBytes(), response.getOutputStream());

		return mav;
}

private String mapFileToMime(String type) {
		if (type.equalsIgnoreCase(".gif")) {
			return "image/gif";
		} else if (type.equalsIgnoreCase(".jpg")) {
			return "image/jpg";
		} else if (type.equalsIgnoreCase(".jpeg")) {
			return "image/jpg";
		} else if (type.equalsIgnoreCase(".doc")) {
			return "application/msword";
		} else if (type.equalsIgnoreCase(".123")) {
			return "application/vnd.lotus-1-2-3";
		} else if (type.equalsIgnoreCase(".prz")) {
			return "application/vnd.lotus-freelance";
		} else if (type.equalsIgnoreCase(".lwp")) {
			return "application/vnd.lotus-wordpro";
		} else if (type.equalsIgnoreCase(".xls")) {
			return "application/vnd.ms-excel";
		} else if (type.equalsIgnoreCase(".ppt")) {
			return "application/vnd.ms-powerpoint";
		} else if (type.equalsIgnoreCase(".vsd")) {
			return "application/vnd.visio";
		} else if (type.equalsIgnoreCase(".pdf")) {
			return "application/pdf";
		} else if (type.equalsIgnoreCase(".wk4")) {
			return "application/vnd.lotus-1-2-3";
		}
		return "application/octet-stream";
}

Well, this is how I hacked around the problem since it seems to be an IE issue requiring the .pdf extension in the URI.

public ModelAndView binitemHandler(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		String repId = RequestUtils.getStringParameter(request, "RepID", "");
		String withHTML = RequestUtils.getStringParameter(request, "withHTML", "0");
		String fileName = RequestUtils.getStringParameter(request, "Filename", "");
		BinaryItem binitem = null;
		ModelAndView mav = null;
		String ext = "";

			binitem = (BinaryItem) myFacade.getBinItem(repId);

			fileName = binitem.getFilename();
			if (fileName.endsWith(".pdf") && !request.getRequestURI().endsWith(".pdf")) {
				response.sendRedirect(request.getContextPath()+"/binitem.pdf?" + request.getQueryString());
			} else {
				if (fileName != null) {
					int dot = fileName.lastIndexOf('.');
					ext = (dot > 0) ? fileName.substring(dot) : "txt";
				}
				response.setContentType(mapFileToMime(ext));
				response.setHeader("Content-disposition", "inline; filename=" + fileName);
				response.setContentLength(binitem.getBytes().length);
				FileCopyUtils.copy(binitem.getBytes(), response.getOutputStream());
			}

		return mav;
}
