Hello,

I have been trying to get Geoserver 1.0.1 to work with a spatial filter and
keep on getting the following error message:

The URL I was trying to call was:

http://kimba:8081/geoserver/wfs?request=GetFeature&typename=qldrstn&filter=&lt;
Filter><BBOX><PropertyName>GEOMETRY</PropertyName><Box%20srsName="EPSG:8311"

<gml:coordinates>137,-30%20157,-25</gml:coordinates></Box></BBOX></Filter>

I am able to perform other non-spatial filters with no problems (the example
below works fine)
http://kimba:8081/geoserver/wfs?request=GetFeature&typename=qldrstn&filter=&lt;
Filter><PropertyIsEqualTo><PropertyName>QLDRSTN_ID</PropertyName><Literal>6<
/Literal></PropertyIsEqualTo></Filter>

What am I doing wrong?

Thanks
