Java – Android to servlet image upload to the server

I created a servlet that accepts images from the android app that comes to self. I receive bytes on my servlet, however, I want to be able to save the image with the original name on the server. How do I do it. I don’t want to use Apache Commons. Are there other solutions that work for me?

Thanks

Send it as multipart/form-data to the MultipartEntity built into Android With the help of the class request HttpClient API

HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost("http://example.com/uploadservlet");
MultipartEntity entity = new MultipartEntity();
entity.addPart("fieldname", new InputStreamBody(fileContent, fileContentType, fileName));
httpPost.setEntity(entity);
HttpResponse servletResponse = httpClient.execute(httpPost);

Then in the servlet’s doPost() method, extract the portion using Apache Commons FileUpload.

try {
    List<FileItem> items = new ServletFileUpload(new DiskFileItemFactory()).parseRequest(request);
    for (FileItem item : items) {
        if (item.getFieldName().equals("fieldname")) {
            String fileName = FilenameUtils.getName(item.getName());
            String fileContentType = item.getContentType();
            InputStream fileContent = item.getInputStream();
            // ... (do your job here)
        }
    }
} catch (FileUploadException e) {
    throw new ServletException("Cannot parse multipart request.", e);
}

I dont want to use apache commons

Use this unless you are using Servlet 3.0 that supports multipart/form-data HttpServletRequest #getParts() out of the box, you need to reinvent a multipart/form data parser yourself according to RFC2388. It will only bite you in the long run. Hard. I don’t really see any reason why you don’t use it. Is it simple ignorance? At least not that hard. Just put commons-fileupload.jar and commons-io.jar into the /WEB-INF/lib folder and use the example above. Nothing more. You can find another example here.
