Hi,
You'll need a setter for the gradebookService API that you are injecting.
Might be easiest to inject into SakaiProxy, you can see the config in
components.xml already. Then add a setter to it like the rest of the Sakai
services are. Then add your method stub to SakaiProxy.java and implement it
in SakaiProxyImpl.java
I posted a message about which service to use in a different thread, keep an
eye on responses there as well.
cheers,
Steve
