        package santosh;          import java.io.bufferedreader;         import java.io.ioexception;         import java.io.inputstreamreader;         import java.net.httpurlconnection;         import java.net.url;          import com.mongodb.db;         import com.mongodb.dbcollection;         import com.mongodb.dbcursor;         import com.mongodb.dbobject;         import com.mongodb.mongoclient;         import com.mongodb.util.json;          public class gopharmatest {              @suppresswarnings("deprecation")             public static void main(string[] args) {                 string response="";                 mongoclient mongoclient=new mongoclient("localhost", 27017);                 db db = mongoclient.getdb("admin");                 dbcollection collection = db.getcollection("product");                  string url = "user web service";                  url obj;                 try {                      obj = new url(url);                     httpurlconnection con = (httpurlconnection) obj.openconnection();                      // optional default                     con.setrequestmethod("get");                      //add request header                     //con.setrequestproperty("user-agent", user_agent);                      //int responsecode = con.getresponsecode();                     //stringbuffer response = new stringbuffer();                      bufferedreader in = new bufferedreader(                             new inputstreamreader(con.getinputstream()));                     string inputline;                      while ((inputline = in.readline()) != null) {                         response+=inputline;                     }                     in.close();                 } catch (ioexception e) {                     // todo auto-generated catch block                     e.printstacktrace();                 }                  dbobject dbobject = (dbobject)json.parse(response);                 collection.insert(dbobject);                  dbcursor cursordoc = collection.find();                 while (cursordoc.hasnext()) {                     system.out.println(cursordoc.next());                 }                 system.out.println("done");             }         }

basicdblist can't used inserts of multiple documents, it's used arrays inside single document. bulk insert, need pass array of dbobjects insert method instead.

as per java doc insert() can accept either single dbobject or array or list of them.

so, in order save, need convert json array array/list of dbobjects, or save each array's item

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
