You probably get an instance of an implementation of the java.sql.Blob interface specific to your JDBC driver. This causes the ClassCastException.
A possible solution could be to create a new class derived from DatabaseConfiguration and overload the getProperty() method. In this method you first call the super method and then check if its result is of type java.sql.Blob. If this is the case, you can use the methods of the Blob interface to extract the data and return it as String. I assume this would work.
