So it must be having trouble reading location.xsd? Do you get any warnings to
that effect?
Aside: Your earlier example used WFS1_1? GML2 is only used by WFS1.0.
This GML utility class is a helper class trying to make the Parser / Encoder /
Configuration easier to use. It looks like you may need to try using them
directly so we can sort out what the issue is.
There are some test cases here:
-
http://svn.osgeo.org/geotools/trunk/modules/extension/xsd/xsd-gml2/src/test/java/org/geotools/gml2/
In particular this one seems to parse and encode with both correct and
incorrect schema location?
-
http://svn.osgeo.org/geotools/trunk/modules/extension/xsd/xsd-gml2/src/test/java/org/geotools/gml2/GMLApplicationSchemaParsingTest.java
Justin could we get your input on this one; I would like to update the GML
utility class so that this code example works.
