I have two different applications deployed on the same jboss4.0.4.GA server. Each application using its own persistence unit. Persistent units declared in persistent.xml (<persistence-unit name="app1">, <persistence-unit name="app2">). Both applications using ejb3 entity beans with same name. This name is very common (Event) and i have no possibility to refactor applications and rename beans. Jboss rises exception when applications deployed. Is it normal behavior? | org.hibernate.AnnotationException: Use of the same entity name twice: Event | at org.hibernate.cfg.annotations.EntityBinder.bindEntity(EntityBinder.java:221) | at org.hibernate.cfg.AnnotationBinder.bindClass(AnnotationBinder.java:531) | at org.hibernate.cfg.AnnotationConfiguration.processArtifactsOfType(AnnotationConfiguration.java:452) | at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:268) | at org.hibernate.cfg.Configuration.buildMappings(Configuration.java:1039) | at org.hibernate.ejb.Ejb3Configuration.buildMappings(Ejb3Configuration.java:1211) | at org.hibernate.ejb.EventListenerConfigurator.configure(EventListenerConfigurator.java:154) | at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:847) | at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:385) | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3993035#...
