When you try to get JPA2 running on WebLogic 10.3 you might get this exception:

java.lang.NoSuchMethodError: javax/persistence/spi/PersistenceUnitInfo.getValidationMode()Ljavax/persistence/ValidationMode;
    at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:632)
    at org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory(HibernatePersistence.java:72)
    at org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean.createNativeEntityManagerFactory(LocalContainerEntityManagerFactoryBean.java:268)
    at org.springframework.orm.jpa.AbstractEntityManagerFactoryBean.afterPropertiesSet(AbstractEntityManagerFactoryBean.java:310)

The reason is that WebLogic loads all JPA classes with the system classloader but ships JPA1. You have to force WebLogic to load the classes from within the lib folder of your web application.

Add to WEB-INF/weblogic.xml in your WAR project:


And additionally add to META-INF/weblogic-application.xml in your EAR project:


It seems both is necessary.

  1. Can I simply just say what a relief to discover someone who
    actually understands what they are talking about
    on the internet. You certainly understand how to bring an issue to
    light and make it important. More and more people need to look at this

    certainly possess the gift.

  3. If the majority of ratings are either 1-star or 5-star, then people are already using the rating they like best – I don't like it/I like it. So if people, when faced with a 5-level rating, unconsciously subvert into a love it/hate it thumbs up/thumbs down system, then that's the rating system they really prefer to use.What's going to be more fun is when you change the system to a binary one and people start complaining it's too limited. %)Kind of ironic, in a convoluted sort of way 🙂
