[geotk] CRS issue with WFS module

[Stephane Fellah]

Martin,

Yes, definitely we will test it. You plan to deploy 4.0.4 on maven repo
will work for us.
Please note that the CRS URL is truncated in the WFSFeatureStore


The code snippet that breaks is in the WFSFeatureStore.java  (line 138)

//extract the feature type -----------------------------------------
CoordinateReferenceSystem crs;
FeatureType sft;
try {
    String defaultCRS = ftt.getDefaultCRS();
    if(defaultCRS.contains("EPSG")){
        final int last = defaultCRS.lastIndexOf(':');
       * defaultCRS = "EPSG:"+defaultCRS.substring(last+1);*
    }
    crs = CRS.forCode(defaultCRS);
    if (getLongitudeFirst()) {
        crs = AbstractCRS.castOrCopy(crs).forConvention(AxesConvention.RIGHT_HANDED);
    }
    sft = requestType(typeName);
}


Simone has redeployed the WFS using the short version "EPSG:4326" to see if
the problem is solved, However, we ran into another issue with Geoserver.
The coordinates of lat/long are flipped when the short version is used on
Geoserver.
Only the preservation of the full URL will keep the order lat/long. I will
forward to you the email thread related to this problem.




Regards
