[Building Sakai] Creating an Entity Provider from scratch issues

[Aaron Zeckoski]

Yes. At a minimum you have to implement the method in:
https://source.sakaiproject.org/svn/entitybroker/trunk/api/src/java/org/sakaiproject/entitybroker/entityprovider/EntityProvider.java.

You cannot register something which does not implement that interface.

More typically you would implement the methods in:
https://source.sakaiproject.org/svn/entitybroker/trunk/api/src/java/org/sakaiproject/entitybroker/entityprovider/capabilities/RESTful.java

Check out the example app which does the latter.

You could have only a single xml file (applicationContext.xml is the default one spring would look for but that is configurable) or you could have as many as you like but importing or configuring spring to use more.
