org.apache.avalon.framework.component.ComponentManager.lookup()
Get the Component associated with the given key. For instance, If the ComponentManager had a LoggerComponent stored and referenced by key, I would use the following call:
```
 try { LoggerComponent log; myComponent = (LoggerComponent) m_manager.lookup(LoggerComponent.ROLE); } catch (...) { ... } 
```
@param key The key name of the Component to retrieve. @return the desired component @throws ComponentException if an error occurs
