OK are you running the latest source code from trunk, at least the
dhis-service-importexport and dhis-web-importexport modules?

The file you sent imports beautifully here.

>>
>> <ogr:Name>Badjia</ogr:Name>

>> *3.* Import the GML file into DHIS through the regular import interface
>> (no need to zip it)
>>

>> *4.* In the GIS module, make sure the Administrator - Map Source setting
