Bug: When defining ArcSDE data as the data source for DDE, the Specify Input Data Source dialog is empty


hen using the Define Data Source wizard and defining the ReaderType Geodatabase_SDE for the ArcIMS Data Delivery Extensions or DDE, the Spatial Assistant dialog Specify Input Data Source is empty.


To use the Geodatabase_SDE reader, ArcGIS Desktop must be installed and licensed because DDE uses the ArcGIS API to read and write geodatabase data.

This is also true of the ReaderType Geodatabase_MDB.


  1. Install ArcGIS Desktop on the same machine as the ArcIMS Data Deliver Extension.
  2. To make an ArcGIS license available, start ArcMap or ArcCatalog on the same machine while defining the data source.
