[ http://opensource.atlassian.com/projects/hibernate/browse/ANN-332?page=co... ] Mufaddal commented on ANN-332: ------------------------------ Seeing a similar problem here. Just upgraded to hibernate 3.2.1 GA I have two classes like such: @Entity @Cache(usage=CacheConcurrencyStrategy.NONSTRICT_READ_WRITE) public class Category implements TanEntity, Imageable { ... @Id private String id; @Version private Long version = null; .... .... @CollectionOfElements @OneToMany(cascade = CascadeType.ALL) @MapKey(name = "name") @JoinColumn @Cascade(org.hibernate.annotations.CascadeType.DELETE_ORPHAN) private Map<String, CategoryAttribute> attributeValues = new HashMap<String, CategoryAttribute>(); .... .... } @Entity @Cache(usage=CacheConcurrencyStrategy.NONSTRICT_READ_WRITE) public class CategoryAttribute implements TanEntity { @Id @GeneratedValue(generator = "system-uuid") @GenericGenerator(name = "system-uuid", strategy = "uuid") private String id; @Version private Long version; private String name; @CollectionOfElements @org.hibernate.annotations.MapKey(columns={@Column(name="productCount")}) @Column(name="productCount", nullable=false, columnDefinition="INTEGER UNSIGNED") private Map<String, Integer> values = new HashMap<String, Integer>(); .... .... } Both classes are mapped in the hibernate.cfg.xml file like such: .... .... <mapping class="com.ac.tan.core.beans.CategoryAttribute"/> <mapping class="com.ac.tan.core.beans.Category"/> .... When I deploy my web application, I see the following trace in my tomcat logs: 1534 ERROR org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/t] listenerStart [3696] - Exception sending context initialized event to listener instance of class com.ac.tan.web.TanContextListener org.hibernate.AnnotationException: Use of @OneToMany or @ManyToMany targeting an unmapped class: com.ac.tan.core.beans.Category.attributeValues[com.ac.tan.core.beans.CategoryAttribute] at org.hibernate.cfg.annotations.CollectionBinder.bindManyToManySecondPass(CollectionBinder.java:1016) at org.hibernate.cfg.annotations.CollectionBinder.bindStarToManySecondPass(CollectionBinder.java:567) at org.hibernate.cfg.annotations.MapBinder$1.secondPass(MapBinder.java:80) at org.hibernate.cfg.CollectionSecondPass.doSecondPass(CollectionSecondPass.java:43) at org.hibernate.cfg.Configuration.secondPassCompile(Configuration.java:1127) at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:296) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1283) at com.ac.tan.core.TanContext.configHibernate(TanContext.java:403) at com.ac.tan.core.TanContext.startup(TanContext.java:209) at com.ac.tan.web.TanWebApplication.startup(TanWebApplication.java:134) at com.ac.tan.web.TanContextListener.contextInitialized(TanContextListener.java:23) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:3692) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4127) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:759) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:739) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:524) at org.apache.catalina.startup.HostConfig.deployDirectory(HostConfig.java:910) at org.apache.catalina.startup.HostConfig.deployDirectories(HostConfig.java:873) at org.apache.catalina.startup.HostConfig.deployApps(HostConfig.java:474) at org.apache.catalina.startup.HostConfig.start(HostConfig.java:1118) at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:310) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:119) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1020) at org.apache.catalina.core.StandardHost.start(StandardHost.java:718) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1012) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:442) at org.apache.catalina.core.StandardService.start(StandardService.java:450) at org.apache.catalina.core.StandardServer.start(StandardServer.java:680) at org.apache.catalina.startup.Catalina.start(Catalina.java:536) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:275) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:413) Any pointers? -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
