我正在尝试在 WebSphere 8.5 中部署一个 Web 应用程序。该应用程序具有以下特点。

  • 莫哈拉 2.1.13
  • Primefaces 3.4.2
  • 春季网络流2.3.1
  • 春天 3.1.2
  • JDK 1.6

这个应用程序在 Tomcat 7 中运行良好，但是当我们尝试将其部署到 WebSphere 中时，我们得到了NullPointerException以下堆栈跟踪。

我看到错误来自 MyFaces2，默认情况下 JSF 实现到 websphere 8.5，所以我尝试将 Mojarra 2.1.13 实现为共享库，但它不起作用（我按照 IBM 文档中的步骤操作）。

另一个奇怪的事情是应用程序渲染了主页，但是当它突然渲染时，这个错误就出现了。

  • 有人知道这个错误吗？

皮耶罗，

要解决此问题，请在 web.xml 文件中添加或替换以下上下文参数并重新发布项目。

<context-param>
<param-name>javax.faces.PARTIAL_STATE_SAVING</param-name>
<param-value>false</param-value>
</context-param>

那是因为您正在为 WAS (myFaces) 使用默认的 JSF 实现，并且您是在 mojarra 中开发的，所以您需要设置它才能使用 myFaces。

我有：

  1. JSF 莫哈拉 2.1.7
  2. Primefaces 3.4.2
  3. Spring框架4.0.2.RELEASE
  4. Spring web flow 2.3.3.RELEASE
  5. 春季安全 3.2.0.RELEASE

我在这种模式下解决了：

  1. 更改 PARENT_LAST 中模块的类加载器

    ibm 文档（更改类加载器策略）

  2. 更改 JSF 提供程序

    ibm 文档（更改 jsf 提供程序）

  3. 重启服务器（重要！）
