I've got an EAR app which uses the old fashion Hibernate3 (org.springframework.orm.hibernate3.LocalSessionFactoryBean). The deployment fails on a ClassNotFoundException: Caused by: java.lang.NoClassDefFoundError           at org.springframework.orm.hibernate3.LocalSessionFactoryBean.class$(LocalSessionFactoryBean.java:174)           at org.springframework.orm.hibernate3.LocalSessionFactoryBean.<init>(LocalSessionFactoryBean.java:174)           at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) [rt.jar:1.6.0_31]           at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39) [rt.jar:1.6.0_31]           at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) [rt.jar:1.6.0_31]           at java.lang.reflect.Constructor.newInstance(Constructor.java:513) [rt.jar:1.6.0_31]           at org.springframework.beans.BeanUtils.instantiateClass(BeanUtils.java:100)           ... 24 more Caused by: java.lang.ClassNotFoundException: org.hibernate.cfg.Configuration from [Module "org.springframework.spring:snowdrop" from local module loader @7f56b6b9]           at org.jboss.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:190)           at org.jboss.modules.ConcurrentClassLoader.performLoadClassUnchecked(ConcurrentClassLoader.java:468) The EAR/lib dire contains the hibernate-core (which contains org.hibernate.cfg.Configuration) and I've added the org.hibernate exclusion to the deployment structure. Any help would be appreciated.
