The ITE uses Eclipse Link as an object relational mapping layer.
The ITE is tested with Oracle. Other database solutions supported by Eclipse Link may also be used as a database, though these have not been tested by our team.
Some databases which limit the row size (like MySQL) have problems with Jubula if they are set to use multi-byte encodings like UTF8. Try to use single-byte encodings like latin1 if you encounter any problems.
