Getting capabilities from tomcat's Geoserver fails

Question

I wanna teke capabilities from tomcat's geoserver. Use this.

wms = new OpenLayers.Format.WMSCapabilities();
OpenLayers.Request.GET({
    url:"http://localhost:8080/geoserver/wms/filedata?request=GetCapabilities",
    success: function(e){
        var response = wms.read(e.responseText);
var capability = response.capability;
for (var i=0, len=capability.layers.length; i<len; i+=1) {
    var layerObj = capability.layers[i];
    if (layerObj.name === 'filedata') {
        map.zoomToExtent(OpenLayers.Bounds.fromArray(layerObj.llbbox));
        break;
    }
}
    }
});

But firebug says that "capability is not defined" in this string

for (var i=0, len=capability.layers.length; i<len; i+=1) {

If i write url from capability request in browser get error

XML Parsing Error: XML or text declaration not at start of entity

But if look in firebut that can see that application was geted capabilities.

In standalone Geoserver all work fine.

Service parameter is mandatory for making requests to WMS services. Your URL should looks like:

http://localhost:8080/geoserver/wms/filedata?request=GetCapabilities&service=WMS
