Hi all , I'm some trouble to write CustomGenerator with cocoon 2.1.10. It work fine with 2.1.4.
A snippet of code: public class DatabaseGenerator extends ServiceableGenerator implements CacheableProcessingComponent, Disposable { ... ... @Override public void service(ServiceManager manager) throws ServiceException { super.service(manager); ComponentSelector selector = (ComponentSelector)manager.lookup(DataSourceComponent.ROLE + "Selector"); ---- this line throw an exception this.datasource = (DataSourceComponent) selector.select(this._datasource); conn = this.datasource.getConnection(); } .... ... ..... ...... } When call a generator cocoon throw an exception when try to obtain the ComponentSelector: java.lang.ClassCastException: org.apache.avalon.framework.service.WrapperServiceSelector at sidera.cocoon.generation.DatabaseGenerator.generate(DatabaseGenerator.java:127) at org.apache.cocoon.components.pipeline.AbstractProcessingPipeline.processXMLPipeline(AbstractProcessingPipeline.java:579) at org.apache.cocoon.components.pipeline.impl.AbstractCachingProcessingPipeline.processXMLPipeline(AbstractCachingProcessingPipeline.java:279) at org.apache.cocoon.components.pipeline.AbstractProcessingPipeline.process(AbstractProcessingPipeline.java:780) at org.apache.cocoon.components.source.impl.SitemapSource.toSAX(SitemapSource.java:413) at org.apache.cocoon.components.source.SourceUtil.toSAX(SourceUtil.java:101) at org.apache.cocoon.components.source.SourceUtil.parse(SourceUtil.java:321) Any suggestion ?? Regards RG |

The code is similar to an example on documentation on cocoon.
This code works fine with 2.1.4.
