Hi there,
I tried to query a WFS-getFeatureRequest to (a local and also a public)
geoserver. The connect was successful but the reading of features fails with
the following exception:
org.opengis.referencing.NoSuchAuthorityCodeException: No code "EPSG:26713"
from authority "EPSG" found for object of type "EngineeringCRS" accompanied
from a parsing exception.
I use:
- Java JDK 1.6.0_27
- Windows 7
- GeoTools 8.0-M2
- GeoServer 2.1.2
I did the following to avoid the exception:
1. Add 'srsName=EPSG:31467' to the request parameter
2. Add the coordinateReferenceSystem to the query with the following code:
CRSAuthorityFactory epsgFactory =
ReferencingFactoryFinder.getCRSAuthorityFactory("EPSG", null);
CoordinateReferenceSystem crSystem =
epsgFactory.createCoordinateReferenceSystem("31467");
query.setCoordinateSystem(crSystem);
3. Use rather a FeatureIterator over a
WFSDataStore#getFeatureSource(typeName);
But nothing really helped.
I run into the same trouble when I request "public" GeoServers. I noticed
that the CRS from WFSDataStore returns always null.
My first assumption was, there is something wrong with the
CoordinateReferenceSystem because its always null.
But further investigation reveals that the parsing process continues despite
the NoSuchAuthorityCodeException. The actual trouble occurs while build up
the elementIndex from the underlaying xsd and assigning QName to an
XSDElementDeclaration. There was no elementDeclaration found for the given
QName. elementDeclaration was null and the following parsing process failed.
Perhaps the application deals with the wrong xsd (iso19112.xsd)? The
according getRequest is added below (see public issue).
The latter mentioned issues are happened to a public server.
Below the exception and the code I used for the local test.* (***LOCAL
ISSUE***)*.
Next, the getRequests and exceptions for the public request.* (***PUBLIC
ISSUE***)*
Ciao,
and thanks in advance
mannie
