I have developed a custom GP tool in C# which does a bunch of processing on a given layer.
It works great in ArcMap on all machines that I have deployed it to. I created a model which uses this tool and want to publish it as a geoprocessing services. It worked without any problems on our testing machine (This was probably because the testing machine has Arcgis Desktop, as well as Server, & I published the service using the ArcCatalog on that machine itself).
Today I had to deploy it to our production server. This does not have ArcGIS Desktop. So I registered the DLL using ESRIRegasm on the server. But No matter what I do, I can't get a Geoprocessing service running using the custom tool. I tried placing the toolbox on the server and publishing it. It did get published, but when I conusmed it from ArcMAp, I got the error "ERROR 000816: The tool is not valid".
Over on ESRI forums, there have been just a few threads about this issue; And the only one which was marked as resolved, talked of registering the dll using the /codebase switch. (this was with ArcGIS 9.3.1)
Has anyone succesfully deployed a custom geoprocessing tool to a server, with ArcGIS server but not ArcGIS desktop?
