我试图部署在WebSphere 8.5 Web应用程序。 该应用程序具有以下特点。

  • 钻嘴鱼科2.1.13
  • Primefaces 3.4.2
  • 春季Webflow的2.3.1
  • 春天3.1.2
  • JDK 1.6

这个程序工作得非常好到Tomcat 7，但是当我们试图将它部署到WebSphere我们得到了一个NullPointerException与下面的堆栈跟踪。

我看到的错误是从MyFaces2，JSF实现由默认到WebSphere 8.5来了，所以我试图实现钻嘴鱼科2.1.13作为共享库，但它没有工作（我跟着来自IBM的文档中的步骤）。

另一个奇怪的是，该应用程序呈现的主页但是当它突然呈现这个错误出现。

  • 是否有人知道一些有关这个错误？

Answer 1:

皮耶罗，

要解决此问题，添加或更换在web.xml文件中以下上下文参数并重新发布该项目。 

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

那是因为你使用的是默认的JSF实现为WAS（MyFaces的），并已在钻嘴鱼科开发的，所以你需要设置，为了与MyFaces的工作。

问候



Answer 2:

我有：

  1. JSF钻嘴鱼科2.1.7
  2. Primefaces 3.4.2
  3. Spring框架4.0.2.RELEASE
  4. Spring Web Flow的2.3.3.RELEASE
  5. 春季安全3.2.0.RELEASE

我决定在这种模式下：

  1. 在PARENT_LAST模块的变更类加载器

    IBM文档（其他城市的类加载器策略）

  2. 改变JSF提供

    IBM文档（JSF变化提供）

  3. 重新启动服务器（重要！）
