WebOffice can use some generic services, e.g. for extensions like WebOffice ePaper. Therefore, create a directory ServiceDocuments in your <ArcGIS Server location>. This directory will be used for storing all map documents published with ArcGIS Server.
Copy the mxd files
•SynMapService.mxd
•SynPlotService.mxd
•SynePaperService.mxd
•SynExtractService.mxd
From
WebOffice10R3-DVD\SampleProject\projects\mxd
To
<ArcGIS Server location>\ServiceDocuments
Note: You should store all map documents served by ArcGIS Server in this central location <ArcGIS Server location>\ServiceDocuments. This way you always know at one click about the map documents served by ArcGIS Server.
If you e.g. have set the ArcGIS Server Location in ArcGIS Server Post Installation to E:\arcgisserver then the mxd files will reside in E:\arcgisserver\ServiceDocuments.
Note: If you have chosen a different location to store the Sample Project geodata then please check the file system access rights of the copied data files. ArcSOC user account respectively local Windows Users group must have read and write access rights.
For productive systems it is recommended not to use the Service Documents location but a local mxd editing location and to update mxds using the Refresh Project button of WebOffice author. See WebOffice10R3_UserManual.pdf, chapter File Menu for details.
