Stand alone Java app accessing remote server throws access error

I have a stand alone Java application that needs to check for the presence of a given database on various remote Domino servers. All works well when running on a Notes client but running on a server the application can not access the target remote database. When checking on the target server log or console screen a denied access message is reported. Have checked and tested that the server hosting the stand alone Java application has full access to the target server and database.
