Hi Kenneth,
I explored the error log.
The problem is that coordinate systems do not match BUT :
1. The error log says
/The coordinate system (*EPSG:32633*) of layer RissaWMSLayer1 cannot be
different than the coordinate system (*EPSG:32632*) of the map
/2. The wms layer is configured to use /*EPSG:32632 */- in my config.xml
it is written
/ <RasterDefinition name="Image">
<Format>PNG</Format>
<Transparent>true</Transparent>
<BackgroundColor>0xFFFFFF</BackgroundColor>
<Time>current</Time>
<Elevation>0</Elevation>
<SpatialContext>*EPSG:32632*</SpatialContext>
<Layer name="VERANDA">
.......
/3. The service supports this coordinate system - in GetCapabilities
document I have
<SRS>EPSG:32633</SRS>
<BoundingBox SRS="EPSG:32633" minx="218329.98786561"
miny="7160648.90075887" maxx="305197.974972341" maxy="7041546.39019898"/>
*<SRS>EPSG:32632</SRS>
<BoundingBox SRS="**EPSG:32632" minx="506720" miny="7147644"
maxx="604333" maxy="7037305"/>
*<SRS>EPSG:32634</SRS>
<BoundingBox SRS="EPSG:32634" minx="-68103.0343048812"
miny="7200948.9760428" maxx="7352.92691530631" maxy="7073836.91252369"/>
<SRS>EPSG:9804</SRS>
<BoundingBox SRS="EPSG:9804" minx="1017422.41132931"
miny="9427477.01214373" maxx="1234782.60719126" maxy="9172903.66920839"/>
-
So, I want the map and WMS layer to be in coordinate system *32632*, the
Feature source is configured to use this coordinate system, the service
supports it, but still the server sends the output in *32633.*
Can you spot my mistake ?
