[jboss-jira] [JBoss JIRA] Resolved: (EJBTHREE-1151) When using a MappedSuperclass then application is not deployable

When using a MappedSuperclass then application is not deployable ---------------------------------------------------------------- Key: EJBTHREE-1151 URL: http://jira.jboss.com/jira/browse/EJBTHREE-1151 Project: EJB 3.0 Issue Type: Bug Components: EJB3 Extensions Affects Versions: AS 4.2.2.GA Reporter: Roland Burgermann Assigned To: Carlo de Wolf Attachments: ejb3xfire-core-1.0-SNAPSHOT.jar, source-files.zip I have tagged a class with the stereotype <<MappedSuperClass>> which holds some general attributes. As described in the EJB3 specification i didn't have a DAO implementation class, because they are not necessary. But when i try to deploy my application with JBoss 4.2.2.GA i got the following error: 2007-12-04 15:03:51,328 DEBUG [org.jboss.ejb3.Ejb3Module] Initialization failed jboss.j2ee:service=EJB3,module=ejb3xfire-core-1.0-SNAPSHOT.jar java.lang.ClassNotFoundException: No ClassLoaders found for: com.company.samples.ejb3xfire.GeneralEntityDaoImpl at org.jboss.mx.loading.LoadMgr3.beginLoadTask(LoadMgr3.java:306) at org.jboss.mx.loading.RepositoryClassLoader.loadClassImpl(RepositoryClassLoader.java:521) at org.jboss.mx.loading.RepositoryClassLoader.loadClass(RepositoryClassLoader.java:415) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at org.jboss.ejb3.Ejb3DescriptorHandler.getContainers(Ejb3DescriptorHandler.java:303) at org.jboss.ejb3.Ejb3Deployment.deployBeansFromLib(Ejb3Deployment.java:465) ....... The whole stack trace can be found in the JBoss forum. When i'm using JBoss 4.0.5.GA with the EJB3 RC9 Patch 1 then my application is startable. Edit @ 10th December 2007: I found a solution to solve this problem. I removed the following entry from the jboss.xml <session> <ejb-name>GeneralEntityDao</ejb-name> </session> and removed the following entry from the ejb-jar.xml <session> <description> <![CDATA[ ]]> </description> <ejb-name>GeneralEntityDao</ejb-name> <local>com.trinitec.samples.ejb3xfire.GeneralEntityDao</local> <ejb-class>com.trinitec.samples.ejb3xfire.GeneralEntityDaoImpl</ejb-class> <session-type>Stateless</session-type> <transaction-type>Container</transaction-type> </session> After this two changes, i can start up JBoss with my application and everything is working fine for the moment. Can i remove this two entries, or will this produce another problem somewhere else? And why is this running on JBoss 4.0.5.GA + EJB3 RC9 Patch 1? Some checks are missing in JBoss 4.2.2.GA?
