Class org.springframework.orm.jpa.EntityManagerHolder does not implement the requeste
Hi,
After having class loader problems trying to use Spring 2.5.5 with Toplink Essentials in GlassFish V2, I decided to use Hibernate as the JPA provider. That solved the problem, but created a new one. It seems to execute my query, but then has some problem which causes a rollback. Then there's some other problem in Spring because of this rollback:
applicationContext.xmlCode:[ERROR] AbstractEntityManagerImpl - -Unable to mark for rollback on PersistenceException: <java.lang.IllegalStateException> java.lang.IncompatibleClassChangeError: Class org.springframework.orm.jpa.EntityManagerHolder does not implement the requested interface org.springframework.transaction.support.ResourceHolder at org.springframework.transaction.support.ResourceHolderSynchronization.afterCompletion(ResourceHolderSynchronization.java:100) at org.springframework.transaction.support.TransactionSynchronizationUtils.invokeAfterCompletion(TransactionSynchronizationUtils.java:133) at org.springframework.transaction.support.AbstractPlatformTransactionManager.invokeAfterCompletion(AbstractPlatformTransactionManager.java:904) at org.springframework.transaction.support.AbstractPlatformTransactionManager.triggerAfterCompletion(AbstractPlatformTransactionManager.java:879) at org.springframework.transaction.support.AbstractPlatformTransactionManager.processCommit(AbstractPlatformTransactionManager.java:707) at org.springframework.transaction.support.AbstractPlatformTransactionManager.commit(AbstractPlatformTransactionManager.java:632) at org.springframework.transaction.interceptor.TransactionAspectSupport.commitTransactionAfterReturning(TransactionAspectSupport.java:314) at org.springframework.transaction.interceptor.TransactionInterceptor.invoke(TransactionInterceptor.java:116) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:171) at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:204) at $Proxy44.getProperty(Unknown Source) at com.example.model.UserContext.getTest(UserContext.java:22) 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:597) at javax.el.BeanELResolver.getValue(BeanELResolver.java:261) at javax.el.CompositeELResolver.getValue(CompositeELResolver.java:143) at com.sun.faces.el.FacesCompositeELResolver.getValue(FacesCompositeELResolver.java:64) at com.sun.el.parser.AstValue.getValue(AstValue.java:138) at ......
