[OpenLayers-Users] WFS request as a Post erros

[Myeong Hun Jeong]

Dear list.

I am using openlayers2.7 and geoserver.

After loading WMS layer, I request WFS as a Post.



function wfsQuery()

    {

        data = "<?xml version='1.0' encoding='UTF-8' ?>" +

                "<wfs:GetFeature service='WFS' version='1.0.0' " +

                    "xmlns:topp='http://www.openplans.org/topp' " +

                    "xmlns:wfs='http://www.opengis.net/wfs' " +

                    "xmlns:ogc='http://www.opengis.net/ogc' " +

                    "xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' "+

                    "xsi:schemaLocation='http://www.opengis.net/wfs " +

                    "http://schemas.opengis.net/wfs/1.0.0/wfs.xsd'> " +

                    "<wfs:Query typeName='topp:states'> " +

                        "<ogc:Filter> " +

                            "<ogc:PropertyIsEqualTo>" +


"<ogc:PropertyName>STATE_FIPS</ogc:PropertyName>"
+

                                "<ogc:Literal>48</ogc:Literal>" +

                            "</ogc:PropertyIsEqualTo>" +

                        "</ogc:Filter> " +

                        "</wfs:Query> " +

                "</wfs:GetFeature>";







        var responseObj = new OpenLayers.Ajax.Request("
http://localhost:8888/geoserver/wfs",

                {   method: 'post',

                     postBody: data,

                     onComplete: wfsResponse

                }

            );

    }

function wfsResponse(transport) {

gmlParser = new OpenLayers.Format.GML();

        features = gmlParser.read(transport.responseText);

         var styleMapSimple = new OpenLayers.StyleMap({

                strokeColor: "black",

                strokeWidth:1,

                fillColor: "orange",

                fillOpacity: 0.7,

            });



       var layerStyled = new OpenLayers.Layer.Vector("result", {styleMap:
styleMapSimple});

        layerStyled.addFeatures(features);

        map.addLayer(layerStyled);

    }



But, I encounter an error message.

The error message is that

<?xml version="1.0" encoding="UTF-8"?>

<ows:ExceptionReport version="1.0.0"

  xsi:schemaLocation="http://www.opengis.net/ows
http://localhost:8888/geoserver/schemas/ows/1.0.0/owsExceptionReport.xsd"

</ows:ExceptionText>

  </ows:Exception>

</ows:ExceptionReport>



How to solve this error?
