FYI, the problem disappeared when I deleted my layers and re-created them -
my layers now retrieve the data, both when the URL in the WFS Data Store is
..
*
http://maitdevgi:8080/geoserver/wfs?service=WFS&version=1.0.0&request=GetCapabilities
*
or ..
*http://maitdevgi:8080/geoserver/wfs?service=WFS&request=GetCapabilities<http://maitdevgi:8080/geoserver/wfs?service=WFS&version=1.0.0&request=GetCapabilities>
*
(The layers in the latter WFS data store display the data inverted in the
Open Layers preview, though.)
The reason for doing this, though, was to try to have Geoserver #1 getting
data from Geoserver #2 using *zipped GML*.
Although, I tick '*Use gzip encoding if server supports it*', the requests
on Geoserver #2 are always '*outputFormat = GML2*' for 1.0.0 and '*outputFormat
= text/xml; subtype=gml/3.1.1*' for 1.1.0.
The 1.1.0 GetCapabilities includes GML2-GZIP, so I thought that this should
be requested ..
<ows:Parameter name="outputFormat">
<ows:Value>text/xml; subtype=gml/3.1.1</ows:Value>
<ows:Value>GML2</ows:Value>
<ows:Value>GML2-GZIP</ows:Value>
<ows:Value>SHAPE-ZIP</ows:Value>
<ows:Value>csv</ows:Value>
<ows:Value>gml3</ows:Value>
<ows:Value>json</ows:Value>
<ows:Value>text/xml; subtype=gml/2.1.2</ows:Value>
</ows:Parameter>
If you have used the TRY_GZIP option successfully, can you tell me where I
am going wrong?
