尝试基于以下对象建立应用程序时收到错误：SPRING-DATA-JPA,GWT项目.
尝试以托管模式运行时,出现异常：

Nested in org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor#0’: Initialization of bean Failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘entityManagerFactory’ defined in URL [file:/**/www/WEB-INF/classes/applicationContext.xml]: Invocation of init method Failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build EntityManagerFactory:

这是我的applicationContext.xml：

没有GWT集成的相同配置可以正常工作.
任何帮助将是有用的！
