[Building Sakai] How to get site id

[Steve Swinsburg]

Is theToolManager dependency injected correctly? How are you injecting  
it? Via Spring directly (setting up your impl as a bean and setting it  
as a property etc) or getting it from the ComponentManager? Post your  
relevant injection code.

cheers,
Steve
