在 Weblogic 12c 中部署 EAR 时出现 NullPointerException

【问题标题】：NullPointerException at deployment of EAR at Weblogic 12c在 Weblogic 12c 中部署 EAR 时出现 NullPointerException
【发布时间】：2014-08-02 17:09:25
【问题描述】：

我们将应用程序从 Weblogic 9.2 迁移到 Weblogic 12.1.2。由于未记录的 NullPointerException，使用管理控制台部署 EAR 失败。在大量搜索此堆栈跟踪和错误消息后，我们发现很少。 One OTN Thread 与类似主题指出 Weblogic Classpath 和 EAR 中的 JAR 加倍。于是我们在Weblogic Installation和EAR中搜索了JAR加倍。 EAR 已打包 xml-apis-1.3.02.jar 并且 WL 类路径包含 xml-apis.jar。从 EAR 中删除 xml-apis-1.3.02.jar 并进行新部署后，我们再次遇到相同的 NullPointerException。

  • 请向我们展示相关的日志文件条目，包括 NPE 的完整堆栈跟踪。
  • How to create a Minimal, Complete, and Verifiable example
  • The Stacktrace of the NullPointerExeption on Pastebin
  • 使用 Jad 反编译 StatefulSessionManager.class 以找出 NPE 的来源。似乎有缓存或交换器为空。两者都是由 public void setup(BaseEJBRemoteHomeIntf, BaseEJBLocalHomeIntf, BeanInfo, Context, EJBCache) 初始化的，这是一个错误吗？ public void undeploy() { super.undeploy();缓存.clear();缓存.stopScrubber();交换器.destroy(); }
  • 我遇到了类似的问题（但其他库），Weblogic 12.1.1 和 12.1.2 没有成功部署 EAR。我正在寻找解决方案，解决它的唯一方法是更新到 Weblogic 12.1.3。它还有其他部署问题（EJB 缓存问题），这些都是可以解决的。那么下面提到的错误是否已修复？ （见 cpurdy 的回答）

标签： java deployment weblogic ear weblogic12c


【解决方案1】：

首先，我不认为您粘贴的异常是“真正的”错误，而是另一个错误的症状。它无法激活更改，即安装您的 .ear 文件。该例外没有帮助。如果我不得不猜测日志中某处还有另一个错误。通常，类路径上的欺骗 jar 会导致 NoClassDefFoundError 或 ClassNotFoundException。检查那些。

其次，如果您的部署与默认 weblogic 类路径之间存在类冲突，您可以尝试将其添加到 weblogic.xml 以强制它使用您耳中的库：

<wls:prefer-application-packages>
    <wls:package-name>package.that.conflicts.*</wls:package-name>
</wls:prefer-application-packages>

    【解决方案2】：

    我将在此记录一个错误以确保对其进行查看。你永远不应该得到 NPE。

    • 谢谢。你能提供错误ID吗？
