Hello all,
I got a question about queryable layer. I noticed that there are some discuession about not getting query layer working. I am running into this problem too. I tried all the suggestion from the previous suggestion; however, I still couldn't make it work. What I tried is to get the demo working with the cities layer queryable. I modified gmap_context.xml to make cities layer point to my mapfile and enable queryable as following:
<Layer queryable="1" hidden="0">
<Server service="WMS" version="1.1.0" title="Cities">
<OnlineResource xlink:type="simple" xlink:href="http://localhost/cgi-bin/mapserv_40.exe?map=C:/ms4w/apps/gmap/htdocs/gmap75_wms.map&"/>
</Server>
<Name>popplace</Name>
<Title>Cities</Title>
<SRS>EPSG:42304 EPSG:42101 EPSG:4269 EPSG:4326 EPSG:42304</SRS>
<FormatList>
<Format current="1">image/png</Format>
<Format>image/gif</Format>
<Format>image/jpeg</Format>
<Format>image/wbmp</Format>
</FormatList>
<StyleList>
</StyleList>
</Layer>
Then I modified the cities layer in my mapfile as followed:
LAYER
NAME "popplace"
METADATA
"wms_title" "Cities"
"RESULT_FIELDS" "NAME"
END
TYPE POINT
STATUS ON
DATA popplace
PROJECTION

END
LabelItem "Name"

END
COLOR 0 0 0
END
Transparency 0
END # Layer
However, I still couldn't make it working. It pop-up a window and said "no queryable layer found", but i did specific cities layer as queryable. I am a newbie to chameleon. Could anyone give me some hint on this problem? Any help would be greatly appreciated.
Thanks in advance.
