Still trying, and have no joy from the WFS layer.
I set the isBaseLayer: true, and this succeeded in removing the issue surrounding the javascript maxExtent error. I verified my projection info, wfs_srs and wms_srs are set to EPSG:4326, and my layer projection is now set to "init:EPSG:4326", however, I still get a blank map. My firebug skills are virtually non-existent, and I have stumbled around, failing to locate the request for the WFS-layer as Arnd recommended. At this point, I am totally flailing (and failing). Other details that might prove relevant, Mapserver 4.10 on windows, and as mentioned before, I get a properly formed XML document with all shape info and column values and attributes when doing an URL getFeature request. Can anyone who has set up a mapserver WFS request in OL possibly post the relevant excerpts from their map file, and javascript calls? I am somewhat at a loss as to other parameters, having tried the request with and without "featureClass: OpenLayers.Feature.WFS" in the additional parameters field.

Something like this: http://geturl.asp?http%3A//localhost/mapserv.exe%3Fmap%3DTreppen.map <http://geturl.asp?http%3A/localhost/mapserv.exe%3Fmap%3DTreppen.map> %26typename%3DPOI %26maxfeatures%3D10 %26SERVICE%3DWFS %26VERSION%3D1.0.0 %26REQUEST%3DGetFeature %26SRS%3DEPSG%253A4326 %26BBOX%3D6.416875%2C50.556875%2C7.823125%2C51.963125 Retrieve the Url with your Internet Explorer and you should get some xml. If not than i would think your proxy is not right or your mapfile. If you cut the SRS and BBOX from the Url and then get an answer, it looks like you have a problem with the projections in your mapfile. To get my own WFS-layer working, i have learned 1. if the SRS in the request is the same as the WFS-layer, I only have to declare a projection in the layer block 2. if the SRS in the request is different from the WFS-layer, I have to declare the requested SRS as 'wfs_srs' 'EPSG:xxxx' in the WEB block and the projection in the LAYER block of the WFS-layer. Then my data will reproject and show in OpenLayers. You have also declare 'wms_srs' in the WEB block for the requested SRS. What I not understand, is, when I'm right with my mapfile, I must have for different requested SRS an own mapfile.

September 2007 22:06 An: [email protected] Betreff: [OpenLayers-Users] trouble with WFS and Mapserver I am having a hard time getting my mapserver to serve up WFS layers (or accessing them via OpenLayers, I really don't know which). I have tested the mapserver with WMS, and all is good. I am able to retrieve WFS data from mapserver via an URL request for getfeature, however, I get no success when trying to load it into openlayers via WFS, just a blank map. In the javascript error console, all I get is an error that the "maxExtent has no properties", indicating that there are no valid layers, I assume, which is of course evidenced by the fact that my map is blank. My creation statement and mapserver layer description is as follows: OL: layer1 = new OpenLayers.Layer.WFS( "poli_bounds", url, {'typename': 'poli_bounds'}, { typename: 'poli_bounds', featureNS: 'http://www.openplans.org/topp', extractAttributes: false } ); MAPFILE: LAYER CONNECTIONTYPE postgis CONNECTION "host=localhost user=postgres password=*** dbname=wsp" NAME poli_bounds GROUP poli_bounds TYPE POLYGON STATUS DEFAULT DUMP TRUE DATA "the_geom from poli_bounds" FILTER "1 = 1" TEMPLATE drought.html #MINSCALE 1000 #MAXSCALE 50000 LABELITEM "name" CLASS NAME "Political Boundaries" SYMBOL 'circle' SIZE 3 COLOR -1 -1 -1 BACKGROUNDCOLOR 0 0 0 OUTLINECOLOR 0 0 0 LABEL COLOR 8 8 174 #SHADOWCOLOR 218 218 218 #SHADOWSIZE 2 2 TYPE TRUETYPE FONT arial SIZE 7 ANTIALIAS TRUE POSITION CC PARTIALS FALSE MINDISTANCE 300 MINFEATURESIZE 30 BUFFER 4 #MINSCALE 1000 #MAXSCALE 50000 END # end of label END TOLERANCE 10 PROJECTION # EPSG SRID = 4326 "proj=latlong" END METADATA "DESCRIPTION" "Political Boundaries" "RESULT_FIELDS" "name county state" "wfs_title" "poli_bounds" ## REQUIRED "gml_featureid" "gid" ## REQUIRED "gml_include_items" "all" ## Optional (serves all attributes for layer) "title" "Political Boundaries" "tablename" "Political Boundaries" END END Robert W.
