javascript - Google maps API showing blank map when given LatLng cords from HTML5 Geolocation -


i'm trying use html5's geolocation features. have function coordinates , use coordinates in call google maps api. if manually specify latitude , longitude works great, reason doesn't work way, empty map, controls there, no actual map. believe code correct, maybe overlooked something.

here's code:

var x = document.getelementbyid("msg");     function getlocation() {         if (navigator.geolocation) {             navigator.geolocation.getcurrentposition(showposition, showerror);         }         else { x.innerhtml = "geolocation not supported browser."; }     }      function showposition(position) {         var mapoptions = {             center: new google.maps.latlng(position.coords.latitude + ", " + position.coords.longitude),             zoom: 5,             maptypeid: google.maps.maptypeid.roadmap         };         var map = new google.maps.map(document.getelementbyid("map"), mapoptions);         var acoptions = {             types: ['establishment']         };         var autocomplete = new google.maps.places.autocomplete(document.getelementbyid('autocomplete'), acoptions);         autocomplete.bindto('bounds', map);         var infowindow = new google.maps.infowindow();         var marker = new google.maps.marker({             map: map         });          google.maps.event.addlistener(autocomplete, 'place_changed', function () {             infowindow.close();             var place = autocomplete.getplace();             if (place.geometry.viewport) {                 map.fitbounds(place.geometry.viewport);             } else {                 map.setcenter(place.geometry.location);                 map.setzoom(17);             }             marker.setposition(place.geometry.location);             infowindow.setcontent('<div><strong>' + place.name + '</strong><br />');             infowindow.open(map, marker);             google.maps.event.addlistener(marker, 'click', function (e) {                  infowindow.open(map, marker);              });         });          var x = document.getelementbyid("msg");         x.innerhtml = position.coords.latitude + ", " + position.coords.longitude;     }      function showerror(error) {         switch (error.code) {             case error.permission_denied:                 x.innerhtml = "user denied request geolocation."                 break;             case error.position_unavailable:                 x.innerhtml = "location information unavailable."                 break;             case error.timeout:                 x.innerhtml = "the request user location timed out."                 break;             case error.unknown_error:                 x.innerhtml = "an unknown error occurred."                 break;         }     }     google.maps.event.adddomlistener(window, 'load', getlocation);

the latlng constructor takes 2 arguments(and optional third) both numeric 1 latitude , other longitude, not both concatenated string .

center: new google.maps.latlng(position.coords.latitude, position.coords.longitude),

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
