Opanlayers Reprojection Kml layer

Question

I have a map with 'EPSG:32639' projection for base map and 'EPSG:4326' projection for kml layer that show on base map. It just show my basemap and do not show any kml layer. what's wrong with that?

My source code is ther.

function initMap(){
            // if this is just a coverage or a group of them, disable a few items,
            // and default to jpeg format
            format = 'image/png';

            var bounds = new OpenLayers.Bounds(
                551438.385, 3602649.973,
                571430.791, 3627258.571
            );
            var options = {
                controls: [
                                            new OpenLayers.Control.Navigation( {mouseWheelOptions: {interval: 100}}),
                    new OpenLayers.Control.PanZoomBar(),
                                            new OpenLayers.Control.NavToolbar(),
                    new OpenLayers.Control.LayerSwitcher({'ascending':false}),
                    new OpenLayers.Control.Permalink(),
                    new OpenLayers.Control.ScaleLine(),
                    new OpenLayers.Control.MousePosition(),
                                            new OpenLayers.Control.Scale($('scale')),
                                            new OpenLayers.Control.OverviewMap(),
                    new OpenLayers.Control.KeyboardDefaults(),
                                            new OpenLayers.Control.ZoomBox({alwaysZoom:true})
                                            ],
                maxExtent: bounds,
                projection: 'EPSG:32639',
                units: 'm',
                                    maxResolution: 136.21203906250003,
                                    numZoomLevels: 10,
            };
            map = new OpenLayers.Map('map', options);


            tiled = new OpenLayers.Layer.TileCache('ESFAHANMAP',
             ['http://www.memap.ir/map'],'ESFAHANMAP',{'format':'image/jpeg',sphericalMercator: true, buffer: 0 });


                            kmlLayer = new OpenLayers.Layer.Vector('Points', 'point.kml',{
                                    projection: new OpenLayers.Projection('EPSG:4326')
                            });
                            map.addLayers([tiled,kmlLayer]);
            map.zoomToExtent(bounds);

        }

Well, you can't show different projections on the same map. You need to reproject features from your KML to the same projection that you basemap has. See the example here
