http://nagoya.apache.org/bugzilla/show_bug.cgi?id=22931 ExcaliburComponentManagerCreator does not recognize ROLE+"Selector" Summary: ExcaliburComponentManagerCreator does not recognize ROLE+"Selector" Product: Avalon Version: unspecified Platform: All OS/Version: All Status: NEW Severity: Normal Priority: Other Component: Excalibur AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Hi guys, I've found that ExcaliburComponentManagerCreator does not recognize a role configuration with added "Selector" to configure a component/service selector. He throws a ClassNotFoundException. I'll give you some sample code: ----------------------------------------------------------------- A) Client: package component2; import java.io.ByteArrayInputStream; import org.apache.avalon.excalibur.component.ExcaliburComponentManagerCreator; import org.apache.avalon.framework.service.ServiceManager; import org.apache.avalon.framework.service.ServiceSelector; import org.apache.commons.lang.ArrayUtils; public class TestServiceSelector { public static final String ROLE_CONFIG = "<role-list>" + "\n <role shorthand='selector' name='component2.ServiceSelector' default-class='org.apache.avalon.excalibur.component. ExcaliburComponentSelector'>" //+"\n <role shorthand='selector' name='component2.Service' default-class='org.apache.avalon.framework.service.DefaultServiceSelector'>" +"\n <hint shorthand='i1' class='component2.impl.Service1'/>" + "\n </role>" + "\n</role-list>"; public static final String COMPONENT_CONFIG = "<test>" + "\n <selector>" + "\n <i1 name='select1'/>" + "\n </selector>" + "\n</test>"; public static final String LOG_CONFIG = "<logkit>" + "\n <factories>" + "\n <factory type='sysout' class='org.apache.avalon.excalibur. logger.factory.StreamTargetFactory'/>" + "\n </factories>" + "\n <targets>" + "\n <sysout id='root'>" + "\n <stream>System.out</stream>" + "\n <format type='pattern'>%6.6{priority} %19.19{time: yyyy-MM-dd HH:mm:ss}: %{message}\n%{throwable}</format>" + "\n </sysout>" + "\n </targets>" + "\n <categories>" + "\n <category name='system' log-level='INFO'>" + "\n <log-target id-ref='root'/>" + "\n </category>" + "\n </categories>" + "\n</logkit>"; public TestServiceSelector() { super(); } public static final void main(String[] args) { System.out.println("### ROLE:\n" + ROLE_CONFIG); System.out.println("### COMPONENT:\n" + COMPONENT_CONFIG); ExcaliburComponentManagerCreator creator = null; try { creator = new ExcaliburComponentManagerCreator( null, new ByteArrayInputStream(LOG_CONFIG.getBytes()), new ByteArrayInputStream(ROLE_CONFIG.getBytes()), new ByteArrayInputStream(COMPONENT_CONFIG.getBytes()), null); ServiceManager manager = creator.getServiceManager(); Object object = manager.lookup(Service.ROLE + "Selector"); System.out.println("Got instance of: " + object); System.out.println("Interfaces: " + ArrayUtils.toString(object. getClass().getInterfaces())); ServiceSelector selector = (ServiceSelector) object; Service select1 = (Service) selector.select("select1"); System.out.println("Got instance of: " + select1); selector.release(select1); manager.release(selector); } catch (Throwable e) { e.printStackTrace(); } finally { creator.dispose(); } } } ----------------------------------------------------------------- B) Service interface (as simple as possible): package component2; public interface Service { public static final String ROLE = Service.class.getName(); } ----------------------------------------------------------------- C) Service implementation: package component2.impl; import org.apache.avalon.framework.thread.ThreadSafe; import component.Service; public class Service1 implements Service, ThreadSafe { public Service1() { super(); } public String toString() { return this.getClass().getName(); } } ----------------------------------------------------------------- Running the client results in this stack trace: java.lang.ClassNotFoundException: component2.ServiceSelector [...] at component2.TestServiceSelector.main(TestServiceSelector.java:48) Working without "Selector" in configuration XML as well as when requesting the component/service works. BUT all documentation I've found states that the above code should work! I'm working with following versions of Avalon/Excalibur JAR files: - avalon-framework-4.1.4.jar - excalibur-component-1.1.jar - excalibur-i18n-1.0.jar - excalibur-instrument-1.0.jar - excalibur-logger-1.0.1.jar - excalibur-pool-1.2.jar - logkit-1.2.jar - commons-collections.jar - commons-lang-2.0.jar Greetings Christian --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
