[jira] Commented: (COCOON-2106) DatabaseReader and SQLTransformer cannot obtain datasource

["Carsten Ziegeler (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/COCOON-2106?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12517912 ] 

Carsten Ziegeler commented on COCOON-2106:
------------------------------------------

Just as an additional note: the way using the selectors is regarded as "old style" and "deprecated". The way using ROLE/key is the preferred way.

> The DatabaseReader and SQLTransformer components fail to obtain the configured data source and throw a ServiceException like "Component with 'org.apache.avalon.excalibur.datasource.DataSourceComponent/personnel' is not defined in this service manager. (Key='AvalonServiceManager')". The failing function call in both cases is:
> this.manager.lookup(DataSourceComponent.ROLE + '/' + datasourceName)
> The result is the same regardless of whether the data source is defined as an Avalon component or a Spring bean.
> Changing the code to use ServiceSelector as in the "Creating a Reader" document [1] and the modular database actions solves the problem for both cases. The attached patch applies this modification to DatabaseReader.java.
