Hello, I'm trying to send a file to a Servlet. Along with this file, I also have to send some parameters (i.e. name/id, date and a few others). I'm using HttpClient on client-side and ServerFileUpload on server-side.
This is the client-side code: ...
String url = "http://localhost:8080/RicezioneServlet/RicezioneServlet";
HttpClient httpclient = new DefaultHttpClient();
HttpPost postMethod = new HttpPost(url);
MultipartEntity mpe = new MultipartEntity();
//I'm sending a .zip file
ContentBody cb = new FileBody(fileToSend,"application/zip");
mpe.addPart("file", cb);
postMethod.setEntity(mpe);
HttpResponse resp = httpclient.execute(postMethod);
HttpEntity respEntity = resp.getEntity();
System.out.println(resp.getStatusLine());
...
on the server side, we've got:
ServletFileUpload sup = new ServletFileUpload();
FileItemIterator it = sup.getItemIterator(request);
FileItemStream item = it.next();
InputStream ios = item.openStream();
//read from ios and write to a fileoutputstream.
Now, I don't know how to add the aforementioned parameters to the request... I tried to use a StringBody and to add it to the MultiPartEntity, but I get a NullPointerException at:
String author = request.getParameter("author");
which means that the parameter isn't seen as a parameter, maybe?
The only was I got it working was setting these parameters as Headers (setHeader and getHeader), but this is not an option.
Any advice? Or maybe can you redirect me to a full example of file+parameter upload?
Thanks,
Alex
