org.apache.avalon.framework.service.ServiceManager.lookup()
Get the Object associated with the given key. For instance, If the ServiceManager had a LoggerComponent stored and referenced by key, the following could be used:
```
 try { LoggerComponent log; myComponent = (LoggerComponent) manager.lookup( LoggerComponent.ROLE ); } catch (...) { ... } 
```
@param key The lookup key of the Object to retrieve. @return an Object value @throws ServiceException if an error occurs
