Thanks a lot, Joanne.
But unfortunately, it doesn't work as well even if I connect the MDB(2000-2003) via the OLE DB Connection. I copy these data to C:\temp, and create a OLE DB connection according to your steps, and I add the spatial data and OLE DB into ArcMap, then I join them via the same PIN. It shows another more warning: Layer does not have a feature template set, and doesn't work also. And the layer would be removed automatically when I double check this warning. Is it strange?
Additional, I just check the Feature Access instead of Tiled Mapping when publishing in the Capabilities of Service Editor in ArcMap.
Of course, it could be published to ArcGIS Online after the joined data is exported as a Shp file.
Thanks again.
