How to solve Projection Problem at client side

Question

I want to discuss a scenario here to all.

1. I have developed a Web mapping application in OpenLayers and GeoServer. The customer give us shapefiles with native projection SWREFF99_1330 (EPSG:3008). i published this shapefile on Geoserver after changing its native projection from EPSG:3008 to EPSG:4326 by using ogr2ogr tool. The layer displayed perfectly over Google map layer in my OpenLayers Web Page.

2. Again, I publish this shapefile on GeoServer with its native projection (this time, without changing projection using ogr2ogr tool) and then i go to my page and figure out that the layer was not visible over Google map layer.

Now, my question to all members:

Is there any way to change the native projection from EPSG:3008 to EPSG:4326 at client side (in my OpenLayers web page code) ? so that the layer should display correctly over google base layer as in case 1.

Answer 1

You can project in Openlayers like this:

    var map = new OpenLayers.Map("map", {
  projection: new OpenLayers.Projection("EPSG:3008"),
  displayProjection: new OpenLayers.Projection("EPSG:4326")
}); 

Proj4js is required to do this on the client side.
