So I have:   package test.datasource;   public interface DataSourceComponent extends Component, Configurable, ThreadSafe {   String ROLE = "test.datasource.DataSourceComponent";   MyConnection getConnection() throws Exception; }       public class MyDataSource extends AbstractLogEnabled     implements DataSourceComponent, Configurable, ThreadSafe, Disposable {       public MyDataSource() {}       public void configure( final Configuration configuration ) throws ConfigurationException {       // configure     }       public MyConnection getConnection() throws Exception {       return myconnection;     }       public void dispose() {       // dispose     } }     package test.acting;   public class DatabaseSelectAction extends AbstractDatabaseAction implements ThreadSafe {     private static final Map selectStatements = new HashMap();       public Map act(Redirector redirector, SourceResolver resolver, Map objectModel, String source, Parameters param) throws Exception {         DataSourceComponent datasource = null;           boolean reloadable = Constants.DESCRIPTOR_RELOADABLE_DEFAULT;         if (this.settings.containsKey("reloadable"))             reloadable = Boolean.getBoolean((String) this.settings.get("reloadable"));         try {             Configuration conf =                 this.getConfiguration(param.getParameter("descriptor", (String) this.settings.get("descriptor")),                                       resolver,                                       param.getParameterAsBoolean("reloadable",reloadable));             datasource = this.getDataSource(conf);             System.out.println( "  Connection: " + datasource.getConnection() );             return EMPTY_MAP;           } catch (Exception e) {             throw new ProcessingException( e );         }     } }       public abstract class AbstractDatabaseAction extends AbstractComplementaryConfigurableAction implements Configurable, Disposable {     protected ComponentSelector dbselector;       public void compose(ComponentManager manager) { //throws ComponentException {       try {         this.dbselector = (ComponentSelector) manager.lookup(DataSourceComponent.ROLE + "Selector");         super.compose(manager);       } catch (ComponentException e) { System.out.println("ERR: " + e);}     }       protected final DataSourceComponent getDataSource(Configuration conf) throws ComponentException {         Configuration dsn = conf.getChild("connection");         return (DataSourceComponent) this.dbselector.select(dsn.getValue(""));     }   ...   When I test it, get error:   WARN    (2002-09-24) 14:23.59:343   [sitemap] (/cocoon/test/) HttpProcessor[80][7]/ExcaliburComponentManager: ComponentLocator exception from parent CM during lookup. org.apache.avalon.framework.component.ComponentException: Could not find component             at org.apache.avalon.excalibur.component.ExcaliburComponentManager.lookup(ExcaliburComponentManager.java:246)             at org.apache.cocoon.components.CocoonComponentManager.lookup(CocoonComponentManager.java:236)             at org.apache.avalon.excalibur.component.DefaultComponentFactory$ComponentManagerProxy.lookup(DefaultComponentFactory.java:387)             at org.apache.avalon.excalibur.component.ExcaliburComponentManager.lookup(ExcaliburComponentManager.java:178)             at org.apache.cocoon.components.CocoonComponentManager.lookup(CocoonComponentManager.java:236)             at org.apache.avalon.excalibur.component.ExcaliburComponentManager.lookup(ExcaliburComponentManager.java:178)             at org.apache.cocoon.components.CocoonComponentManager.lookup(CocoonComponentManager.java:236)             at org.apache.avalon.excalibur.component.DefaultComponentFactory$ComponentManagerProxy.lookup(DefaultComponentFactory.java:387)             at org.apache.avalon.excalibur.component.DefaultComponentFactory$ComponentManagerProxy.lookup(DefaultComponentFactory.java:387) ...   How I understood, I should add my Component to manager, how can I do it?     Any ideas, tips, or help would be greatly appreciated,   Hill
