Mongodb/GridFS - Am using reactjs for file upload/download having issue -


am trying upload files , getting error "unable process parts no multi-part configuration has been provided". using reactjs , servlet connect mongodb. please find code below.

upload(data) { ajax({ url: 'api/uploaddocservlet', method: 'post', data: data }, (data) => { console.log("print data::::"+data); if (data.error == null) { this.search({}); } else { alert(data.error); } });  }

api servlet code :

try { system.out.println("uploaddocservlet:::"+request.getpart("data")); (part part : request.getparts()) { string filename = extractfilename(part); object result = service.uploaddoc(filename); response.put("result", result != null ? result : jsonobject.null); } } catch (exception e) { logger.log(level.warning, null, e); response.put("error", e.getmessage()); } resp.setcontenttype("application/json"); resp.setcharacterencoding("utf-8"); resp.adddateheader("expires", 0); printwriter pw = resp.getwriter(); response.write(pw); pw.close(); }  private string extractfilename(part part) { string contentdisp = part.getheader("content-disposition"); string[] items = contentdisp.split(";"); (string s : items) { if (s.trim().startswith("filename")) { return s.substring(s.indexof("=") + 2, s.length()-1); } } return ""; }

file insert in mongodb (java code )

public void uploaddocument(string file) {    string filename = file; filename = new file(filename).getname(); gridfs gfsphoto = new gridfs((db) database, "photo"); gridfsinputfile gfsfile = gfsphoto.createfile(filename); gfsfile.setfilename(filename); gfsfile.save(); system.out.println("saved..."); }

could suggest on same.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
