[Building Sakai] Assignment 2 Entity Broker

[Maurer, Christopher Wayne]

Kelly,
I get the same error against trunk (http://nightly2.sakaiproject.org:8085/portal).  Might want to file a jira on it (or see if one already exists):
https://jira.sakaiproject.org/browse/ASNN

Subject: [Building Sakai] Assignment 2 Entity Broker

Hi All,

I’m running EB 1.4.5 on Sakai 2.8.x and am having problem getting any Assignment2 entities.

For the rest call: /direct/assignment2/:ID:, I got the following errors:

        at org.sakaiproject.entitybroker.util.servlet.DirectServlet.service(DirectServlet.java:130)

For the rest call: /direct/assignment2submission/:ID:, I got this:
HTTP Status 404 - Attempted to access an entity URL path (/assignment2submission/561) for an entity (/assignment2submission/561) that does not exist

I wonder whether anyone have success in using them, and any pointer to fix the errors?

Thanks,
