You have to make sure your DLL is in the classpath   One such way to do so is to put the path to the DLL in PATH environment variable   Other option is to add it to the VM arguments in the variable LD LIBRARY PATH  like this   java -Djava library path  path to my dll -cp  my classpath goes here MainClass

The sqljdbc auth dll is within the sqljdbc x x folder you install to retrieve the sqljdbcxx jar file in the auth folder   Create a lib folder at the base of your scala project and move sqljdbc auth dll into this folder   This makes sure that you are getting the correct file  e g  64 bit or 32 bit that matches your sqljdbcxx jar file
