When I ran the app all was fine & when the tester ran the app it failed with the following Exception:
Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.

It took me ages to work out what the issue was until I noticed that I was connecting to the database as 'sa' & he was using the schema name.
There is a lot of info on the web about this issue concerning changing the systems Regional settings but that was not my issue. In this case the sqlserver user 'sa' had a Default language of 'English' and the schema user had a language of 'British English'. Changing the Default Language to 'English' solved the problem.
