I want to use geocode in our application. so that, I got Google geocoding API and could achieve with Google Maps. Problem is that I wanted to achieve the same with my own map which is having projection EPSG:4326 INSTEAD OF getting geocoded from Google Map which is having projection EPSG:3857. or I am getting a coordinates from Google geocoding projection EPSG:3857 and that coordinates I want to mark on my OpenLayers Map which is having projection EPSG:4326

please help me.

The following piece of code allows you to transform your latitude and longitude coordinates from epsg:3857 to epsg:4326 in just one line. Just substitute longitude and latitudine values to LON and LAT in the code.

point = new OpenLayers.LonLat(LON,LAT).transform('EPSG:4326', 'EPSG:3857');

In point you'll have an OpenLayers readable point.

Asuming you have the latitude and Longitude in the appropriate variables, you can use the following code to project the point:

var epsg4326 = new OpenLayers.Projection('EPSG:4326');
var epsgWebMercator = new OpenLayers.Projection('EPSG:3857');
var pt_latLong=new OpenLayers.Geometry.Point(lon, lat);
var pt_webMercator= pt_latLong.transform(epsg4326,epsgWebMercator);
