Hello Imran, The problem you are facing has nothing to do with openlayers, it is though related with geoserver. I'm not sure if current releases of geoserver already present the json output format but you can always program a template to return your results in json format. Check the following sites and if you have further questions i think you'll have better chances of getting an answer to this problem in the geoserver list.
