Hi,
I am using ApplicationSchemaConfiguration for parsing a gml3 schema (here:
http://cweb.ksat.no/cweb/schema/geoweb/vessel/wfsvd.xsd) with gt 2.4.1
with a test file, when i launch my code i get a null pointer Exception (got
null schema).
but when i ask configuration.schema(), the schema is not null
any help appreciated
Gersh
test xml:
<?xml version="1.0" encoding="UTF-8"?>
