Please edit your question and put it there, instead of in a comment. Also, what is the url of your geoserver? –  Devdatta Tengshe Apr 23 '13 at 9:32

Your OpenLayers.Layer.WMS statements should look like this:

basemap = new OpenLayers.Layer.WMS( "Layer Name1",
    "http://localhost:8080/geoserver/wms/workspacename", {layers: 'workspacename:layername'} );\
utility = new OpenLayers.Layer.WMS( "Layer Name2",
    "http://localhost:8080/geoserver/wms/workspacename", {layers: 'workspacename:layername', transparent:"true"}, {isBaseLayer:false} );

Please consider the version of the your API. Also define suitable projection for your layer.

var layer2 = new OpenLayers.Layer.WMS(maplayer.displayName,
                maplayer.datasource,
                { layers: [2], version: '1.3.0' ,'srs':maplayer.crs},
                  {singleTile: true,
                      isBaseLayer: false,
                      projection: "EPSG:102113"
                  }
                );

layer2.setOpacity(0.52);

map.addLayer(layer2);

It should be enough removing '? service=wms& version=1.1.1& request=GetCapabilities' from the url parameter of the layer declaration
