I am trying to use Enums for EventType , but to map an enum to hibernate I found that we still need to inclde hibernate-annotations jar even if we want to map enums in hbm files.

Is this ok ? can this jar be included in the classpath ?

I would simply use int instead, but if you prefer Enum, feel free to do so.

You can put any additional jar files under web/WEB-INF/lib. When you submit your work, please upload any additional jar files you used together with the csns.zip file.

What access level?

Access control will be implemented using Spring Security, a declarative security framework. For this assignment you don't need to worry about access control.
