android - Worklight HTTP adapter procedure being called multiple times despite being executed only once -


i have application created using worklight 5.0.5. in app make call http adapter retrieve lot of data (all contacts of company); operation takes 1 minute produce response. adapter calls servlet returns of requested data.

a strange thing happens after tap button start call adapter procedure: in servlet logs see after 30 seconds second call arrives same command, didn't tap button or call adapter procedure again!

the procedure timeout set 120 seconds:

<procedure name="getcontlistjson" requesttimeoutinseconds="120"/>

and code call adapter procedure is:

function loadcontactlist(){       if(firstloadcontacts){         loadcontresults = null;         var busy = new wl.busyindicator("content", { text: "caricamento lista contatti..."         });         busy.show(); // show busy indicator         var invocationdata = {             adapter : 'dominoadapterhttp',             procedure : 'getcontlistjson',             parameters : []         };         wl.logger.debug("loading contacts list server");         wl.client.invokeprocedure(invocationdata, {             onsuccess : dojo.hitch(this, function(resultc) {             busy.hide();             wl.logger.debug("load contacts completed: ", resultc);             if (resultc.invocationresult.items.length !== 0) {                 loadcontresults = resultc.invocationresult;                 this.listcontacts();             } else {                 //alert("nessun ordine presente nello stato selezionato");             }         }),         onfailure : dojo.hitch(this, function (result) {             busy.hide();             wl.logger.debug("load contacts failed: ", resultc);             alert("error loading data: " + json.stringify(resultc));         }),         timeout:120000     });      } else {         this.listcontacts();     } }

i cannot understand why second call starts automatically. behavior implies app doesn't continue operations display results , in of cases error "host not available".

edit:

with simplified code had same problem:

var invocationdata1 = {         adapter : 'dominoadapterhttp',         procedure : 'getcontlistjson',         parameters : [] }; wl.logger.debug("loading contacts list server");  wl.client.invokeprocedure(invocationdata1, {     onsuccess : function(resultc){alert('ok!');},     onfailure : function(resultc){alert('ko');},     timeout:120000 });

backend code:

if (command.equalsignorecase("getcontactsjson")){  system.out.println("" + mblappdominoquery.class.getname() + ": getcontacts method called");          long starttime = system.currenttimemillis();          try{             //notesthread.sinitthread();             session newsession = notesfactory.createsession("192.168.x.x","user","pwd");     system.out.println("platform --> " + newsession.getplatform());     system.out.println("username --> " + newsession.getusername());             //system.out.println(system.getproperty("java.library.path"));             database databasenew = newsession.getdatabase ("192.168.x.x", "prj/db.nsf");              view viewclienti = databasenew.getview("(rubrica contatti - tutti)");     system.out.println("# contatti: " + viewclienti.getentrycount());             viewentrycollection vec = viewclienti.getallentries();              viewentry tmpentry;             viewentry entry = vec.getfirstentry();             string jsonresp = "{ \"items\": [";              while (entry != null) {                  string cod = entry.getdocument().getitemvaluestring("company_num");                 string cli = entry.getdocument().getitemvaluestring("company_name");                 string nome = entry.getdocument().getitemvaluestring("fname");                 string cognome = entry.getdocument().getitemvaluestring("lname");                 string mansione = entry.getdocument().getitemvaluestring("mansione");                  if(cli.indexof('\"') != -1 || cli.contains("\"")){                     cli = cli.replace("\"", "\'");                  }                  cli = new mblappdominoquery().removeaccents(cli);                 nome = new mblappdominoquery().removeaccents(nome);                 cognome = new mblappdominoquery().removeaccents(cognome);                  if(mansione != null && mansione.length() > 30)                     mansione = mansione.substring(0, 30) + "...";                 if(cli != null && cli.length() > 30)                     cli = cli.substring(0, 30) + "...";                  string label = "<table><tr><td>" + cognome + " " + nome + "</td></tr><tr><td style=\\\"font-size: small; color: silver;\\\">" + mansione + "</td></tr><tr><td style=\\\"font-size: small; color: silver;\\\">" + cli + "</td></tr></table>";                 string id = "" + cod + "*" + nome + "*" + cognome + "*" + mansione;                   jsonresp += " { \"id\": \"" + id + "\", ";                 jsonresp += " \"moveto\": \"contactdetails_1\", ";                 jsonresp += " \"transition\": \"slide\", ";                 jsonresp += " \"variableheight\": true, ";                 jsonresp += "\"label\": \"" + label + "\" },";                  tmpentry = vec.getnextentry();                  entry.recycle();                  entry = tmpentry;              }              jsonresp = jsonresp.substring(0, jsonresp.length()-1);             jsonresp += "] }";              jsonobject json = new jsonobject();             try {                 json = (jsonobject) new jsonparser().parse(jsonresp);                 //system.out.println("json: " + json);             } catch (parseexception e) {                 // todo auto-generated catch block                 e.printstacktrace();             }              long stoptime = system.currenttimemillis();             long elapsedtime = stoptime - starttime; system.out.println("elaborazione completata in: " + (new simpledateformat("mm:ss:sss")).format(new date(elapsedtime)) + " minuti");             response.setcontenttype("application/json");             response.getwriter().write(json.tostring());           }catch (exception e) {             // todo: handle exception             e.printstacktrace();         }finally{             //notesthread.stermthread();         }    }

php - Why I am getting the Error "Commands out of sync; you can't run this command now" -

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

i'm using named queries fetch entities database using jpa , hibernate , came across puzzling me: how come there no default implementations of javax.persistence.parameter interface? i rather impressed how @staticmetamodel used criteriabuilder in jpa2 meaning type safety , don't have mess around setting string names. wanted apply similar of jpa1 ejb's i'm working on: dealergroup_.class: public dealergroup_ { public parameter<integer> id = new parameterimpl<integer>("id"); /// etc... } dealergroupfacade.class: // ... public dealergroup fetch(integer id) { typedquery<dealergroup> query = em.createnamedquery("dealergroup.fetchbyid", dealergroup.class); query.setparameter(dealergroup_.id, query); return query.getsingleresult(); } // ... i surprised find there no implementations of parameter interface - of course, implement myself absence makes me suspicious may mistake using in way? should implementing parameter...
