This is the problem.

Daisy sets both a session attribute and request attribute named "locale"
containing a java.util.Locale object. Maybe your XSP tries to get such
an attribute but expects there to be something else then a
java.util.Locale object, such as a string. This might be what is done on
line 1036 of the generated java file.
