[Geoserver-devel] Problems with OGC add-on for ArcGIS

I am getting error when trying to use ArcMap with the ESRI OGC add-on, I
can see my layers in Catalog, but when I try to add them I get the
following error:

Layer: topp

The Spatial Reference System code provided by the server cannot by
resolved by ArcMap. Data from this layer cannot be reprojected.

Do I need to change topp to 8307 or WGS84 ? Any ideas ? Thanks.
