[gradebook2-dev] need to restart sakai whenever I make a code change to gradebook2

[Jon Gorrono]

Hi, Kim.

Looks like you *might* be trying to inject the ItemService into the
Gradebook2ComponentService bean via Spring and spring cannot find the
implementation... and I suspect it cannot find the api either.

The ItemService is part of the sample jsf tools in sakai and the api
there is not actually deployed to the tomcat /shared/lib directory nor
is a sakai component created.

You might be able to accomplish what want by modifying the pom.xml in
the samples/sample-tool-jsf to deploy the api class to share/lib

So
 - build sakai with -Pexperimental to include the samples code
 - declare the bean id to be the same as api packaged name:
org.sakaiproject.sample.tool.ItemService
 - make sure the api class (interface class) is deployed to /shared/lib
