AbstractMethodError when deploying Spring + Hibernate + JPA2 as a WAR
Hi,
we have a web application that uses Spring 3, Hibernate 3.5 and and JPA2 and is managed using Maven. When running it through Maven (for example mvn jetty:run), it works perfectly. But strangely, when packaged as a WAR it fails to start.
I created a minimal web application to demonstrate the problem. It actually contains no executable code, it just configures a memory database, Hibernate, JPA and Spring's Dispatcher servlet. When started within maven as mvn jetty:run, and also mvn tomcat:run, it starts as expected. However, when packaged as a WAR and deployed, it fails to start with this exception:
The problem can be also demonstrated by running mvn tomcat:run-war.Code:Caused by: java.lang.AbstractMethodError: org.springframework.orm.jpa.persistenceunit.SpringPersistenceUnitInfo.getSharedCacheMode()Ljavax/persistence/SharedCacheMode; at org.hibernate.ejb.util.LogHelper.logPersistenceUnitInfo(LogHelper.java:39) at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:509) at org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory(HibernatePersistence.java:72) at org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean.createNativeEntityManagerFactory(LocalContainerEntityManagerFactoryBean.java:218) at org.springframework.orm.jpa.AbstractEntityManagerFactoryBean.afterPropertiesSet(AbstractEntityManagerFactoryBean.java:251) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactory.java:1477) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1417) ... 42 more
I'm attaching the demonstration application.
Any idea what is causing the problem and how to solve it? I've been looking for a solution for several hours already, but without success. Presumably it is somehow related to SPR-6408 Add full support for JPA 2.0 PersistenceUnitInfo and SPR-6705 Spring 3.0 not compatible with Hibernate 3.5 beta3. In class org.springframework.orm.jpa.persistenceunit.Defaul tPersistenceUnitManager a presence of JPA2 is checked and if present, the instance of PersistenceUnitInfo is wrapped into a proxy that adds JPA2 specific method. But it looks like the solution is not perfect and in my case it fails.
Thanks for help,
Petr
