We have a geoprocessing service running in ArcGIS Server 10 sp1 java edition. It is basically the same as the population summary/demographics GP Example.
The geoprocessing service runs fine in ArcMap and in ArcGIS Explorer as a service from ArcGIS Server.
We have tried everything
1. Running it locally
2. local jobs folder, etc
3. Both on 9.3.1 and 10
Here is the REST request with the geometry payload to execute the service
Here is the web app (but the map server is internal so you wont be able to see that).
A six pack to the one who can help me with this!
