[Geotools-gt2-users] Problems to parse GML3 with geotools

[Felix S. <fel...@di...>]

Hi everybody,

I have a pproblem with the GML 3 parser from geotools.
I have an GML and a schema, but in the method getImports I get an error 
message, and no result object.

Can somebody find a solution for this problem?

The Error message is:
Dez 12, 2014 1:54:45 PM org.geotools.xml.Schemas getImports
INFORMATION: Schema import wasn't resolved: http://www.opengis.net/gml 
declared location: http://schemas.opengis.net/gml/3.1.1/base/gml.xsd

'http://www.openplans.org/n52', but instance document does not reference 
this schema.

Here is my GML:

Here is my schema:
