我们有一个在 WebLogic 10.3.6 应用服务器中正常运行的 .ear 文件。.ear 使用 Spring 3.0.5 和 Hibernate 3.5.2。

如果我们在另一个 WebLogic 10.3.6 服务器中部署相同的 .ear 文件，我们会收到下一个错误。

org.springframework.web.context.ContextLoader initWebApplicationContext
SEVERE: Context initialization failed

我尝试了几种解决方案：

  • 将 hibernate3.jar 放在 .war/WEB-INF/lib 中（所有 jars 现在都在 .ear/lib 中）
  • 在 .war/WEB-INF/weblogic.xml 中使用 <prefer-web-inf-classes>true</prefer-web-inf-classes>

似乎没有任何效果。我有点迷失在这里...

在网络上进行了广泛的搜索并在 .ear 上进行了反复试验后，我找到了解决问题的方法。

我已更改文件 META-INF/weblogic-application.xml 并在标签 <weblogic-application> 内添加了标签

<prefer-application-packages>
  <package-name>org.apache.*</package-name>
  <package-name>antlr.*</package-name>
</prefer-application-packages>
