MyEclipse9中使用Hibernate3.6.5开发JPA2遇到的问题
今天上午闲来无事，下了个最新的Hibernate3.6.5，打算学习一下JPA2。开发工具是MyEclipse9.0。1.新建Java Project，编写数据库与相应代码，配置等。很顺利的完成。2.新建Web Project，一模一样的代码拷贝过去就出错。错误信息如下：Exception in thread "main" javax.persistence.PersistenceException: [PersistenceUnit: movie] Unable to configure EntityManagerFactoryat org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:378)at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:56)at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:78)at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:54)at com.tanlan.movie.test.TestCountry.testCountry(TestCountry.java:13)at com.tanlan.movie.test.TestCountry.main(TestCountry.java:26)Caused by: org.hibernate.HibernateException: Unable to get the default Bean Validation factoryat org.hibernate.cfg.beanvalidation.BeanValidationActivator.applyDDL(BeanValidationActivator.java:127)at org.hibernate.cfg.Configuration.applyBeanValidationConstraintsOnDDL(Configuration.java:1704)at org.hibernate.cfg.Configuration.applyConstraintsToDDL(Configuration.java:1654)at org.hibernate.cfg.Configuration.secondPassCompile(Configuration.java:1445)at org.hibernate.cfg.Configuration.buildMappings(Configuration.java:1375)at org.hibernate.ejb.Ejb3Configuration.buildMappings(Ejb3Configuration.java:1519)at org.hibernate.ejb.EventListenerConfigurator.configure(EventListenerConfigurator.java:193)at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:1100)at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:282)at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:366)... 5 moreCaused by: java.lang.reflect.InvocationTargetExceptionat 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 org.hibernate.cfg.beanvalidation.BeanValidationActivator.applyDDL(BeanValidationActivator.java:118)... 14 moreCaused by: org.hibernate.HibernateException: Unable to build the default ValidatorFactoryat org.hibernate.cfg.beanvalidation.TypeSafeActivator.getValidatorFactory(TypeSafeActivator.java:383)at org.hibernate.cfg.beanvalidation.TypeSafeActivator.applyDDL(TypeSafeActivator.java:109)... 19 moreCaused by: javax.validation.ValidationException: Unable to instantiate Configuration.at javax.validation.Validation$GenericBootstrapImpl.configure(Validation.java:272)at javax.validation.Validation.buildDefaultValidatorFactory(Validation.java:111)at org.hibernate.cfg.beanvalidation.TypeSafeActivator.getValidatorFactory(TypeSafeActivator.java:380)... 20 moreCaused by: java.lang.NullPointerExceptionat java.util.ResourceBundle.getBundle(ResourceBundle.java:960)at org.hibernate.validator.engine.ResourceBundleMessageInterpolator.loadBundle(ResourceBundleMessageInterpolator.java:202)at org.hibernate.validator.engine.ResourceBundleMessageInterpolator.getFileBasedResourceBundle(ResourceBundleMessageInterpolator.java:182)at org.hibernate.validator.engine.ResourceBundleMessageInterpolator.<init>(ResourceBundleMessageInterpolator.java:81)at org.hibernate.validator.engine.ResourceBundleMessageInterpolator.<init>(ResourceBundleMessageInterpolator.java:73)at org.hibernate.validator.engine.ConfigurationImpl.<init>(ConfigurationImpl.java:57)at org.hibernate.validator.HibernateValidator.createGenericConfiguration(HibernateValidator.java:43)at javax.validation.Validation$GenericBootstrapImpl.configure(Validation.java:269)... 22 more 将工程中的Java EE 6 Library从build path中去掉就可以，搞不懂啊。</init></init></init>
