Update. the last error was solved. I started running the Dataflex Web Application Server with the Local System user and the WebOrder Mobile is working..
But getting the failed to open the explicitly specified database again. It is surely a question of rights on the SQL server.
My webapp is a webservice only application so I am not logging in with a session.
I removed all the available functions in this application and left just a Hello World function. This worked. So it is definitely SQL access rights
In this Hello Function i am showing the user name. On my windows pc it is showing my username whilst on the deployed app it is showing the the server's name with a $
Any ideas pls?
