The API download ZIP contains a file called install.html. I would try those instructions instead of the ones from akela.mendelu.cz. (The akela.mendelu.cz link gives an invalid security certificate error in Firefox, so I didn't actually look at it.)

I wouldn't use a geoprocessing service for this task. I implemented KML export for an app. using an ASP.NET generic handler (.ashx), using the Google Earth KML API for .NET. private static geGeometry JsonToKmlGeometry(Dictionary<string, object> geometry)
{
geGeometry placemarkGeometry;
if (geometry.Keys.Contains("x"))
{
// Create point geometry
// x and y are decimals;
var x = Convert.ToDouble(geometry["x"]);
var y = Convert.ToDouble(geometry["y"]);
placemarkGeometry = new gePoint(new geCoordinates(new geAngle90(y), new geAngle180(x)));
}
else if (geometry.Keys.Contains("rings"))
{
// Create polygon geometry
var rings = (ArrayList)geometry["rings"];
var linearRings = from ArrayList ring in rings
select new geLinearRing((from ArrayList point in ring
select new geCoordinates(
new geAngle90(Convert.ToDouble(point[1])),
new geAngle180(Convert.ToDouble(point[0]))
)).ToList());
if (linearRings.Count() > 1)
{
var polygon = new gePolygon(new geOuterBoundaryIs(linearRings.ElementAt(0)));
polygon.InnerBoundaries.AddRange(from ring in linearRings.Skip(1)
select new geInnerBoundaryIs(ring));
placemarkGeometry = polygon;
}
else
{
placemarkGeometry = linearRings.First();
}
}
else if (geometry.Keys.Contains("paths"))
{
// Create line geometry
var paths = (ArrayList)geometry["paths"];
var lineStrings = from ArrayList ring in paths
select new geLineString((from ArrayList point in ring
select new geCoordinates(
new geAngle90(Convert.ToDouble(point[1])),
new geAngle180(Convert.ToDouble(point[0]))
)).ToList());
if (lineStrings.Count() > 1)
{
var multiGeo = new geMultiGeometry();
multiGeo.Geometries.AddRange(lineStrings);
placemarkGeometry = multiGeo;
}
else
{
placemarkGeometry = lineStrings.First();
}
}
else
{
placemarkGeometry = null;
}
return placemarkGeometry;
} if (Regex.IsMatch(format, "(?i)km[lz]"))
{
// Generate a KML document.
var kmlDocument = new geDocument();
var jsSerializer = new JavaScriptSerializer();
// Loop through the layers.
var layers = jsSerializer.Deserialize<Dictionary<string, object>>(json);
foreach (var kvp in layers)
{
var folder = new geFolder { Name = kvp.Key };
kmlDocument.Features.Add(folder);
var graphics = kvp.Value as ArrayList;
foreach (Dictionary<string, object> graphic in graphics)
{
var placemark = new gePlacemark();
folder.Features.Add(placemark);
placemark.Geometry = JsonToKmlGeometry(graphic["geometry"] as Dictionary<string, object>);
var attributesJson = (Dictionary<string, object>)graphic["attributes"];
attributesJson.Remove("RouteGeometry");
////if (attributesJson.Keys.Contains("BufferedGeometry") && attributesJson.Keys.Contains("BufferSize") && Convert.ToDouble(attributesJson["BufferSize"]) > 0)
////{
//// // TODO: Set the placemark geometry to a multi-geometry containing both the main and buffered geometries.
////}
string desc = ToHtmlDL(attributesJson);
placemark.Description = desc;
}
}
var kml = new geKML(kmlDocument);
// Export the geKML into either KML or KMZ, depending on the specified format.
byte[] bytes;
if (string.Compare(format, "kmz", true) == 0)
{
bytes = kml.ToKMZ();
context.Response.ContentType = "application/vnd.google-earth.kmz";
context.Response.AddHeader("Content-Disposition", "filename=ExportedGraphics.kmz");

bytes = kml.ToKML();
context.Response.ContentType = "application/vnd.google-earth.kml+xml";

You should be able to use the latest version of the API, but there will be some functions that won't work with older versions. The documentation for some functions will specify a minimum ArcGIS Server version.

Have you tried creating the MapOverview widget in the map's OnLoad event?

Your issue was probably the same one discussed here.

Did you include a reference to the esri.css file? This requirement was added to the JS API fairly recently, and if you omit it the results look like what is show in your screenshot.

serverapi.arcgisonline.com was temporarily experiencing heavy load. everything is back up now. sorry for the inconvenience! It was working for me briefly, but now I'm getting the error, "The service is unavailable."

I am having trouble accessing the JavaScript API URL today. The request frequently fails with the following error message: [INDENT]Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.[/INDENT]

I've made a few jQuery plug-ins that interact with the ArcGIS JavaScript API. Note that I wrote these before AMD loading was available, so you'll need to do some tweaking if you want to take advantage of AMD. While the main jQuery library supports AMD, jQuery UI (which I used in my plug-ins) does not. (There are custom versions of jQuery UI that support AMD on github, though.) Another project you might want to look at is jQuery Geo. I haven't used this myself, but it looks like they wrote their own code to read map services (ArcGIS Server among other types) instead of using the ArcGIS JavaScript API.
