Question

在Weblogic：12.2.1上部署EJB应用程序时，我面临异常：

“weblogic.management.DeploymentException：java.lang.NoSuchMethodError：javax.persistence.spi.PersistenceUnitInfo.getValidationMode（）Ljavax / persistence / ValidationMode”

我在persistence.xml中有以下配置来指定持久性提供程序

<persistence-unit name="entityManager">
<!-- Use Hibernate persistency -->  
<provider>org.hibernate.ejb.HibernatePersistence</provider>

weblogic-application.xml

中的

及以下

<prefer-application-packages>
<package-name>antlr.*</package-name>
<package-name>javax.persistence.*</package-name>

在此异常之前，我遇到了异常“异常实例化持久性提供程序类java.lang.ClassNotFoundException：org.hibernate.ejb.HibernatePersistence”，该异常已从

解决

Error instantiating Persistence Provider class java.lang.ClassNotFoundException: org.hibernate.ejb.HibernatePersistence

从那时起我就面临着这个例外

我在WL_DOMAIN / lib中提供了以下jar： -

hibernate-jpa-2.0-api-1.0.1.Final
com.oracle.jpa2support_1.0.0.0_2-1
休眠
DOM4J

还在WL_DOMAIN中的下面文件的类路径中提供了如下所示 ---的setDomainEnv.cmd

设置EXT_PRE_CLASSPATH = C：\ Projects \ GMPP-CBOSS \ MFSS \ MFSS \ lib \ hibernate \ slf4j- api.jar文件; C：\项目\ GMPP-CBOSS \ MFSS \ MFSS \ lib中\休眠\冬眠-JPA-api.jar文件

--- TrivEnv.cmd

设置CLASSPATH = C：\ oracle \ Middleware2 \ modules \ javax.persistence_1.0.0.0_1-0- 2.jar; C：\ ORACLE \ Middleware2 \模块\ com.oracle.jpa2support_1.0.0.0_2- 1.jar;％CLASSPATH％

---- commonEnv.cmd ----- oracle_common / common / bin

设置CLASSPATH = C：\ oracle \ Middleware2 \ modules \ javax.persistence_1.0.0.0_1-0- 2.jar; C：\ ORACLE \ Middleware2 \模块\ com.oracle.jpa2support_1.0.0.0_2-1.jar;

有可能在服务器类路径的开头和结尾添加了javax.persistence_1.0.0.0_2-0-0.jar（在DOMAIN_HOME / lib目录中）。

因此，同一服务器类路径中同一个jar的两个版本会导致不一致。

解从DOMAIN_HOME / lib目录中删除javax.persistence_1.0.0.0_2-0-0.jar。
