1) when trying post file simulator null value storing in server database , receiving "upload successfully" response.
2) when trying post file device not getting null value in server.

please me.

thank you

not sure file types, images can upload, btw, have tried possible examples here, none worked (i had $_files array empty), had construct own, based on examples , works:

- (void) uploadlog :(nsstring *) filepath { nsdata *data = [[nsdata alloc] initwithcontentsoffile:filepath]; nsstring *urlstring =[nsstring stringwithformat:@"http://www.yoursite.com/accept.php"]; // use please use real website link. nsmutableurlrequest *request = [[nsmutableurlrequest alloc] init]; [request seturl:[nsurl urlwithstring:urlstring]]; [request sethttpmethod:@"post"];  nsstring *boundary = @"_187934598797439873422234"; nsstring *contenttype = [nsstring stringwithformat:@"multipart/form-data; boundary=%@",boundary]; [request setvalue:contenttype forhttpheaderfield: @"content-type"]; [request setvalue:@"text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8" forhttpheaderfield:@"accept"]; [request setvalue:@"mozilla/5.0 (macintosh; intel mac os x 10_7_5) applewebkit/536.26.14 (khtml, gecko) version/6.0.1 safari/536.26.14" forhttpheaderfield:@"user-agent"]; [request setvalue:@"http://google.com" forhttpheaderfield:@"origin"];  nsmutabledata *body = [nsmutabledata data]; [body appenddata:[[nsstring stringwithformat:@"content-length %d\r\n\r\n", [data length] ] datausingencoding:nsutf8stringencoding]]; [body appenddata:[[nsstring stringwithformat:@"\r\n--%@\r\n",boundary] datausingencoding:nsutf8stringencoding]]; [body appenddata:[[nsstring stringwithformat:@"content-disposition: form-data; name=\"picture\"; filename=\"%@.png\"\r\n", @"newfile"] datausingencoding:nsutf8stringencoding]];  [body appenddata:[@"content-type: application/octet-stream\r\n\r\n" datausingencoding:nsutf8stringencoding]];  [body appenddata:[nsdata datawithdata:data]];  [body appenddata:[[nsstring stringwithformat:@"\r\n--%@--\r\n",boundary] datausingencoding:nsutf8stringencoding]];   [request sethttpbody:body]; [request addvalue:[nsstring stringwithformat:@"%d", [body length]] forhttpheaderfield:@"content-length"];   nsdata *returndata = [nsurlconnection sendsynchronousrequest:request returningresponse:nil error:nil]; nsstring *returnstring = [[nsstring alloc] initwithdata:returndata encoding:nsutf8stringencoding]; nslog(@"%@", returnstring); }

and here php part works me (sorry, not familiar jsp):

<?php     $target_path = "./uploads/";        $target_path = $target_path . basename( $_files['picture']['name']);        if(move_uploaded_file($_files['picture']['tmp_name'], $target_path)) {       echo "the file ".  basename( $_files['picture']['name'])." has been uploaded";       } else{       echo "there error uploading file, please try again!";       }   ?>
