I am attempting to migrate an EJB 2 application from JBoss 4.0.3SP1 to 4.2.1.GA.
XDoclet is used to generate the ejb files. During server start-up, after rebuilding the ear file, I get the error "Finder findByLevelType defined on ProductDetail should return only instances of ProductDetail but the query results in instances of ProductLevel" The ejbql is defined in ProductLevel but ProductDetail extends ProductLevel. The trace from the server log is: 09:47:20,182 WARN [ServiceController] Problem starting service jboss.j2ee:service=EjbModule,module=bgms_ejb.jar | org.jboss.deployment.DeploymentException: Finder findByLevelType defined on ProductDetail should return only instances of ProductDetail but the query results in instances of ProductLevel | at org.jboss.ejb.plugins.cmp.jdbc.JDBCAbstractQueryCommand.setSelectEntity(JDBCAbstractQueryCommand.java:320) | at org.jboss.ejb.plugins.cmp.jdbc.JDBCEJBQLQuery.(JDBCEJBQLQuery.java:79) | at org.jboss.ejb.plugins.cmp.jdbc.JDBCCommandFactory.createEJBQLQuery(JDBCCommandFactory.java:75) | at org.jboss.ejb.plugins.cmp.jdbc.JDBCQueryManager.start(JDBCQueryManager.java:286) | at org.jboss.ejb.plugins.cmp.jdbc.JDBCStoreManager.startStoreManager(JDBCStoreManager.java:505) | at org.jboss.ejb.plugins.cmp.jdbc.JDBCStoreManager.start(JDBCStoreManager.java:396) | at org.jboss.ejb.plugins.CMPPersistenceManager.start(CMPPersistenceManager.java:172) | at org.jboss.ejb.EjbModule.startService(EjbModule.java:414) | at org.jboss.system.ServiceMBeanSupport.jbossInternalStart(ServiceMBeanSupport.java:289) | at org.jboss.system.ServiceMBeanSupport.jbossInternalLifecycle(ServiceMBeanSupport.java:245) | at sun.reflect.GeneratedMethodAccessor3.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) | at java.lang.reflect.Method.invoke(Unknown Source) | at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155) | at org.jboss.mx.server.Invocation.dispatch(Invocation.java:94) | at org.jboss.mx.server.Invocation.invoke(Invocation.java:86) | at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:264) | at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:659) | at org.jboss.system.ServiceController$ServiceProxy.invoke(ServiceController.java:978) | at $Proxy0.start(Unknown Source) | at org.jboss.system.ServiceController.start(ServiceController.java:417) | at sun.reflect.GeneratedMethodAccessor9.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) | at java.lang.reflect.Method.invoke(Unknown Source) | at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155) | at org.jboss.mx.server.Invocation.dispatch(Invocation.java:94) | at org.jboss.mx.server.Invocation.invoke(Invocation.java:86) | at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:264) | at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:659) | at org.jboss.mx.util.MBeanProxyExt.invoke(MBeanProxyExt.java:210) | at $Proxy29.start(Unknown Source) | at org.jboss.ejb.EJBDeployer.start(EJBDeployer.java:662) | at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) | at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) | at java.lang.reflect.Method.invoke(Unknown Source) | at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155) | at org.jboss.mx.server.Invocation.dispatch(Invocation.java:94) | at org.jboss.mx.interceptor.AbstractInterceptor.invoke(AbstractInterceptor.java:133) | at org.jboss.mx.server.Invocation.invoke(Invocation.java:88) | at org.jboss.mx.interceptor.ModelMBeanOperationInterceptor.invoke(ModelMBeanOperationInterceptor.java:142) | at org.jboss.mx.interceptor.DynamicInterceptor.invoke(DynamicInterceptor.java:97) | at org.jboss.system.InterceptorServiceMBeanSupport.invokeNext(InterceptorServiceMBeanSupport.java:238) | at org.jboss.ws.integration.jboss42.DeployerInterceptor.start(DeployerInterceptor.java:93) | at org.jboss.deployment.SubDeployerInterceptorSupport$XMBeanInterceptor.start(SubDeployerInterceptorSupport.java:188) | at org.jboss.deployment.SubDeployerInterceptor.invoke(SubDeployerInterceptor.java:95) | at org.jboss.mx.server.Invocation.invoke(Invocation.java:88) | at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:264) | at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:659) | at org.jboss.mx.util.MBeanProxyExt.invoke(MBeanProxyExt.java:210) | at $Proxy30.start(Unknown Source) | at org.jboss.deployment.MainDeployer.start(MainDeployer.java:1025) | at org.jboss.deployment.MainDeployer.start(MainDeployer.java:1015) | at org.jboss.deployment.MainDeployer.deploy(MainDeployer.java:819) | at org.jboss.deployment.MainDeployer.deploy(MainDeployer.java:782) | at sun.reflect.GeneratedMethodAccessor54.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) | at java.lang.reflect.Method.invoke(Unknown Source) | ... | | Any ideas?
