[Building Sakai] Failed import of IMS QTI formatted file in question pool throws exception

Fri Jan 29 10:58:51 PST 2010

Hi Doreen,

I think your error is not generated by the un-removed files. Can you please
send me the results of following queries?

select * from sam_questionpool_t

Also, where did the instructor get the QTI XML? Exported from a Tests &
Quizzes assessment?  Can you email me your QTI XML file?

Thanks,
Karen
