[Building Sakai] "UserDirectoryService" or "User" instances from my Tool "SelfCert"

[Steve Swinsburg]

The issue is the case of the first letter of the properties.

In your spring config you have it uppercase:
<property name="UserDirectoryService" 
			ref="org.sakaiproject.user.api.UserDirectoryService" />

In your class you have it lowercase:
private UserDirectoryService userDirectoryService;

cheers,
Steve
