Cannot use non-POJO Hibernate entities with Seam-managed Session ---------------------------------------------------------------- Key: JBSEAM-2418 URL: http://jira.jboss.com/jira/browse/JBSEAM-2418 Project: JBoss Seam Issue Type: Bug Affects Versions: 2.0.0.GA Environment: WinXP, JBoss4.2 Reporter: Dave Sunerton-Burl When trying to use the Map-based mode of a Hibernate session, I get the error below. First, here's the code that causes the error... final Session session = (Session) Component.getInstance("dynamicSession"); final Session mapSession = session.getSession(EntityMode.MAP); final Map record = (Map) mapSession.get("TestEntity", 10001l); ...the last line causes... java.lang.AssertionError: java.lang.IllegalArgumentException: Not an entity class: java.util.HashMap at org.jboss.seam.mock.BaseSeamTest$Request.onException(BaseSeamTest.java:475) at org.jboss.seam.mock.BaseSeamTest$Request$2.doFilter(BaseSeamTest.java:526) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:83) at org.jboss.seam.debug.hot.HotDeployFilter.doFilter(HotDeployFilter.java:68) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) at org.jboss.seam.web.MultipartFilter.doFilter(MultipartFilter.java:85) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) at org.jboss.seam.web.ExceptionFilter.doFilter(ExceptionFilter.java:64) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) at org.jboss.seam.web.RedirectFilter.doFilter(RedirectFilter.java:44) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) at org.ajax4jsf.webapp.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:141) at org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:281) at org.jboss.seam.web.Ajax4jsfFilter.doFilter(Ajax4jsfFilter.java:60) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) at org.jboss.seam.web.LoggingFilter.doFilter(LoggingFilter.java:58) at org.jboss.seam.servlet.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:69) at org.jboss.seam.servlet.SeamFilter.doFilter(SeamFilter.java:158) at org.jboss.seam.mock.BaseSeamTest$Request.run(BaseSeamTest.java:514) at com.fugro.traxx.entities.DynamicEntityTest.changeMappingsAtRuntime(DynamicEntityTest.java:88) Caused by: java.lang.IllegalArgumentException: Not an entity class: java.util.HashMap at org.jboss.seam.Entity.forClass(Entity.java:208) at org.jboss.seam.persistence.PersistenceProvider.getPostLoadMethod(PersistenceProvider.java:154) at org.jboss.seam.security.Identity.checkEntityPermission(Identity.java:678) at org.jboss.seam.security.HibernateSecurityInterceptor.onLoad(HibernateSecurityInterceptor.java:35) at org.hibernate.event.def.DefaultPreLoadEventListener.onPreLoad(DefaultPreLoadEventListener.java:18) at org.hibernate.engine.TwoPhaseLoad.initializeEntity(TwoPhaseLoad.java:125) at org.hibernate.loader.Loader.initializeEntitiesAndCollections(Loader.java:842) at org.hibernate.loader.Loader.doQuery(Loader.java:717) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:224) at org.hibernate.loader.Loader.loadEntity(Loader.java:1851) at org.hibernate.loader.entity.AbstractEntityLoader.load(AbstractEntityLoader.java:48) at org.hibernate.loader.entity.AbstractEntityLoader.load(AbstractEntityLoader.java:42) at org.hibernate.persister.entity.AbstractEntityPersister.load(AbstractEntityPersister.java:2992) at org.hibernate.event.def.DefaultLoadEventListener.loadFromDatasource(DefaultLoadEventListener.java:395) at org.hibernate.event.def.DefaultLoadEventListener.doLoad(DefaultLoadEventListener.java:375) at org.hibernate.event.def.DefaultLoadEventListener.load(DefaultLoadEventListener.java:139) at org.hibernate.event.def.DefaultLoadEventListener.proxyOrLoad(DefaultLoadEventListener.java:195) at org.hibernate.event.def.DefaultLoadEventListener.onLoad(DefaultLoadEventListener.java:103) at org.hibernate.impl.SessionImpl.fireLoad(SessionImpl.java:878) at org.hibernate.impl.SessionImpl.get(SessionImpl.java:815) at com.fugro.traxx.entities.DynamicEntityTest$3.invokeApplication(DynamicEntityTest.java:104) at org.jboss.seam.mock.BaseSeamTest$Request.invokeApplicationPhase(BaseSeamTest.java:652) at org.jboss.seam.mock.BaseSeamTest$Request.emulateJsfLifecycle(BaseSeamTest.java:598) at org.jboss.seam.mock.BaseSeamTest$Request.access$300(BaseSeamTest.java:185) at org.jboss.seam.mock.BaseSeamTest$Request$2.doFilter(BaseSeamTest.java:519) ... 40 more ... Removed 22 stack frames "dynamicSession" is declared in components.xml as... <persistence:managed-hibernate-session auto-create="true" name="dynamicSession"/> The error seems to be connected to the HibernateSecurityInterceptor, which tries to get hold of a real class from the mapping (which doesn't exist - this is a non-POJO mapping). My workaround involved replacing the "org.jboss.seam.persistence.HibernateSessionFactory" with my own implementation which didn't add the interceptor (I will have to do without declarative security on the dynamic entities).
