[Building Sakai] Use of GradebookService as a web service

[Shoji Kajita]

Hi Chuck and Matthew,

Thank you for your advices.

I'm now taking a look on these pointers and getting close to
work. However, I'm still getting the following exception:

java.lang.SecurityException : User shoji attempted to access grade information for student kajita without permission in gb 8e328a23-c343-40cc-bcb0-547553b9cd46 using gradebookService.getGradesForStudentsForItem

As far as I see, "shoji" has the permission to grade because he has the maintain role.

Any thoughts?

Best regards,
Shoji
