When adding a layer from a WMS server Chameleon does not use the required STYLES parameter. This causes the new ESRI WMS connector to not work with Chameleon. Please let me know if this should be posted in Mapserver bugzilla. I use the following workaround: use ?styles=& in the WMS URL: http://192.168.3.107:8080/wmsconnector/com.esri.wsit.WMSServlet/provincies?styles=& From the OGC spec: STYLES=style_list R Comma-separated list of one rendering style per requested layer. Optional if SLD parameter is present.
Bart I am curious as to which version of WMS this is in? I believe this issue should be fixed in the mapserver WMS client (i.e. it should ensure that styles= is in the URL if it is mandatory)
Hi Paul, I just upgraded to the Mapserver 4.2 beta binaries from maptools.org and changed my chameleon cwc2.xml config to php_mapscript_42.dll and the problem is still there. Bart
Mapserver should include the STYLES= parameter in the URL, so it's either that something is missing or set wrong by chameleon, or there is a bug in MapServer's handling of the styles parameter. The URL you provided is probably on your lan, and we don't have access to ArcIMS...could you attach the mapfile, or a context file that I could load in MapServer to try to reproduce? Also, can you please specify how you added the layer to the mapfile? Did you add it by hand, or did you do it via a chameleon widget?
Hi Daniel, this is the URL which is built (I got it from the Apache error log when stopping Tomcat on my machine, you're right that it is a machine in the local network only): http://192.168.3.107:8080/wmsconnector/com.esri.wsit.WMSServlet/provincies? SERVICE=WMS&VERSION=1.1. 1&LAYERS=laag0&QUERY_LAYERS=laag0&FORMAT=image/png&TRANSPARENT=TRUE&REQUEST=GetM ap&WIDTH=800&HEIGHT=560&SRS=EPSG:28992&BBOX=-79713.955357,285935.714286,368593. 187500,599935.714286&EXCEPTIONS=application/vnd.ogc.se_inimage What I do in Chameleon is the following: 1) I added a WMS server through the Manage Server widget 2) I added a layer from this WMS through the treeview widget The treeview is a copy of browseData.php from Chameleon and uses the addWMSLayer function. You can see it in action at: http://www.vz.geodan.nl:1111/geoservices05/ Press the first button which gets the treeview (the service is called ArcIMS@Bart, it has only got one layer). Add the layer by pressing the hyperlink.
I forgot to mention, this is what is written in the session MAP file: LAYER CONNECTION "http://192.168.3.107:8080/wmsconnector/com.esri.wsit.

The problem is in the WMSBrowser widget file. It builds the connection in the map file in the wrong way. WMSBrowser creates all the necessary metadata for MapServer to generate a correct URL but MapServer will not generate a correct URL unless the connection does not include several keys (like version for instance). The fix is to edit WMSBrowser.widget.php lines 581+ that look like this: // build connection string $szConnection = $szURL.$szQuestionMark; ."SERVICE=WMS&VERSION=".$szWMSVersion ."&LAYERS=".urlencode( trim( $axCapRec['name'] ) ) .$szQueryLayers ."&FORMAT=".$szFormat."&TRANSPARENT=TRUE"; and replace with: // build connection string $szConnection = $szURL.$szQuestionMark; /* * this is not required, it should be built from metadata. ."SERVICE=WMS&VERSION=".$szWMSVersion ."&LAYERS=".urlencode( trim( $axCapRec['name'] ) ) .$szQueryLayers ."&FORMAT=".$szFormat."&TRANSPARENT=TRUE"; */ Note that this is untested since I am in the middle of modifying everything in cvs. Bart, please try this and let me know if it works, and I will incorporate the change in cvs.
Paul, you're right. I tested this change in the version of the code we use (though not in WMSBrowser but in the browsedata.php file) and just using the URL without the params for the CONNECTION works. I will set the status to solved, but maybe there are some other parts of Chameleon which have the same piece of code?
Paul, can you verify this bug, it seems in your redesign of Chameleon to 1.99 you commented out the suggested fix..... // build connection string $szConnection = $szURL.$szQuestionMark; /* * this is not required, it should be built from metadata. ."SERVICE=WMS&VERSION=".$szWMSVersion ."&LAYERS=".urlencode( trim( $axCapRec['name'] ) ) .$szQueryLayers ."&FORMAT=".$szFormat."&TRANSPARENT=TRUE"; */ // only add the layer if format is set Also, I am unable to verify since I do not have a client side ArcIMS WMS Connector. Any suggestions?
Bart, please verify this bug.
Verified for WMSBrowser. One thing though, there is one more occurrence of this in the source code, i.e. CatalogSearch.widget.php.
Bart verified, will be closing this bug
