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

        throws Exception
    {
        // since no new components can be declared on sitemap we could
        // very well use the 'other' one here. Anyway, since it's there...
        ComponentManager sitemapManager = CocoonComponentManager.getSitemapComponentManager();
        ComponentSelector outputSelector = (ComponentSelector)sitemapManager
            .lookup(OutputModule.ROLE + "Selector");
        OutputModule output = (OutputModule) outputSelector.select(type);
        try {
            output.rollback(null, this.environment.getObjectModel(), null);
        } finally {
