    Post problem with uploading an image to server

    Hi everyone

    what seems to be the problem in my code, what i want to do is to upload an image to a folder named "uploadFiles" in my web application.

    here's my code, can you guys please help me. What seems to be the problem?


     boolean isMultiPart = ServletFileUpload.isMultipartContent(request);
            try {
     
                if (!isMultiPart) {
                    out.println("File not found!");
                } else {
     
                    ServletFileUpload servletFileUpload = new ServletFileUpload(new DiskFileItemFactory());
                    List fileItemsList = servletFileUpload.parseRequest(request);
                    Iterator it = fileItemsList.iterator();
     
                    while (it.hasNext()) {
     
                        FileItem fileItem = (FileItem) it.next();
                        if (fileItem.isFormField()) {
                            /* The file item contains a simple name-value pair of a form field */
                        } else {
     
                            /* The file item contains an uploaded file */
                            long fileSize = fileItem.getSize();
                            String fileDirectory = fileItem.getName();
                            String contentType = fileItem.getContentType();
                            String[] temp = fileDirectory.split("\\\\"); /*Just to get the file name only*/
                            String fileName = temp[temp.length-1];
                            out.println(fileName);
                            File saveTo = new File("/uploadFiles/" + fileName ); /*at this line is my problem. It won't Upload the browsed Image*/
     
                            try {
                                fileItem.write(saveTo);
                            } catch (Exception ex) {
                                Logger.getLogger(doInputServlet.class.getName()).log(Level.SEVERE, null, ex);
                            }
                        }
                    }
                }

    It helps if you tell us...does it compile? Are there exceptions? Does it misbehave?

    yes it compile and there are no exceptions occur. I tried to print something before the fileItem.write(saveTo) for debugging purposes and surprisingly yes it prints. but when i print another after the said code it doesn't print... Does it mean there's a logical error in my Code?

    Are you positive there is no exception? The behavior you describe sounds like an exception is thrown, in which case the debugging line after the write method call is not called. When you say you 'print', do you mean you do so to the Logger? If not and the logs are not inspected, you might miss an exception as the prints might be sent to different I/O streams, depending upon the configuration
