I get : <gml:Point srsName="http://www.opengis.net/gml/srs/epsg.xml#27700"; xmlns:gml="http://www.opengis.net/gml"; xmlns:xlink="http://www.w3.org/1999/xlink";> <gml:coord><gml:X>278415.0</gml:X><gml:Y>187644.0</gml:Y></gml:coord> </gml:Point>
The SRS format is different from what I saw but I think it's ok. EPSG:27700 is the same SRS that osgb:BNG The answer of the server is : <gml:Polygon xmlns:gml="http://www.opengis.net/gml"; srsName="osgb:BNG"> <gml:outerBoundaryIs> <gml:LinearRing> <gml:coordinates> 278414.650,187643.450 278417.550,187644.600 278420.250,187645.500 278427.300,187647.950 278430.250,187648.950 278434.250,187650.300 278438.850,187651.900 278436.400,187659.350 278431.650,187657.800 278433.550,187652.050 278424.200,187649.000 278423.350,187651.700 278425.350,187652.350 278424.350,187655.450 278421.900,187654.650 278407.350,187649.900 278407.650,187647.800 278408.600,187641.500 278414.650,187643.450 </gml:coordinates> </gml:LinearRing> </gml:outerBoundaryIs> </gml:Polygon> When I parse this GML fragment : FeatureCollection featureCollection = DefaultFeatureCollections .newCollection(); org.geotools.xml.Configuration configuration = new org.geotools.gml2.GMLConfiguration(); configuration.getProperties().add( Parser.Properties.IGNORE_SCHEMA_LOCATION); configuration.getProperties().add( Parser.Properties.PARSE_UNKNOWN_ELEMENTS); org.geotools.xml.Parser parser = new org.geotools.xml.Parser( configuration); Object obj = parser.parse(pis); the parse method raises : java.lang.RuntimeException: Parsing failed for Polygon: org.opengis.referencing.NoSuchAuthorityCodeException: L'autorité "OSGB" n'est pas connue ou ne correspond pas aux indices spécifiés.

The JAR file which defined it may not be reached ?) So I must define this OSGB Authority which is exactly the same that EPSG:27700 I tried that : Hints hints = new Hints(Hints.CRS_AUTHORITY_EXTRA_DIRECTORY, "E:\\eclipse\\eclipse_3.3\\workspace\\com.anwrt.xqueryengine"); AuthorityFactory authority = new FactoryUsingWKT(hints); FactoryFinder.addAuthorityFactory(authority); but it doesn't work. How can I specify a new authority osgb ? Is It possible to specify it from an old one ? Thanks for your help.
