[OpenLayers-Users] Cannot add markers to a map in EPSG:2345

[Yang Zhaohui]

Hello dear evryone,
  A problem is boring me for a long time. I have a shapefile with Xi'an 1980 Gauss-Kruger projected coordinate system. I have added it into Geoserver1.5.3. So I can visit in EPSG:4326(WGS84) and in EPSG:2345(Xi'an80). But When I want to add a marker layer to a Openlayers map (This time the projected coordinate system of the map is EPSG:2345), it cannot diasplay.Could you please give me some suggestion?Thank you very much!

"...
map = new OpenLayers.Map('map', {controls:[], 'projection': 'EPSG:23345', 'units':'m'}); 
...
var  markers = new OpenLayers.Layer.Markers("±ê×¢ËÑË÷");
 
markers.setVisibility(true);
    
map.addLayer(markers);
    
marker= new OpenLayers.Marker(new OpenLayers.LonLat(456144.21976956,360540.12626545), 
              new OpenLayers.Icon("image/marker.png",new OpenLayers.Size(10,15))
                ); 
      
markers.addMarker(marker); 
"
                                                    Sincerely yours,
                                                           Yang
