CXF 2.7.14 + WSS4J + Websphere 7 ClassCastException

本文介绍了CXF 2.7.14 + WSS4J + Websphere 7 ClassCastException的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我们正在使用WSS4JOutInterceptor来签名来自应用程序的传出肥皂消息。我们已经在Tomcat上测试了该应用程序，没有任何问题，但是在Websphere（7）上，我们不断收到ClassCastException：

we are using WSS4JOutInterceptor to sign outgoing soap message from our application. We have tested the application on Tomcat without any problems, but on Websphere (7) we keep getting the ClassCastException: 

java.lang.ClassCastException: org.apache.jcp.xml.dsig.internal.dom.DOMXMLSignatureFactory incompatible with javax.xml.crypto.dsig.XMLSignatureFactory

我知道这通常意味着这两个类使用不同的类加载器加载，但是我无法证明这是我们的情况。

I know this usually means that these two classes are loaded with different classloaders, but I am unable to prove this is our case.

我们的类路径（由Websphere管理控制台打印）如下：

Our classpath (printed by websphere administration console) looks like this:

我们的Web应用程序配置为首先使用本地类加载器（通过WAS管理）。

Our webapp is configured to use local classloader first (through WAS administration).

有趣的事实是：使用我们的Web应用程序重新启动WAS服务器之后，对WS请求进行签名就可以了。但是当重新启动应用程序（不重新启动服务器）时，问题就出现了。

Interresting fact is: After restart of WAS server with our webapp, the signing of WS requests works just fine. But when the application is restarted (without server restart) the problem emerges.

任何想法都可以检查出什么问题？

Any ideas what could be possibly checked for problem?

谢谢，

推荐答案

经过一番研究，我发现这个CXF问题可能会有所帮助：

Then there is the Websphere documentation, which describes recommended approach to use third part JAX-WS engine (like CXF) - here

从手册中复制：


  1. 将类加载器策略设置为在模块级别上首先由本地类加载器加载的类（最后由父级加载）

  1. Set the class loader policy to Classes loaded with local class loader first (parent last) at the module level.

将类加载器策略更改为 parent last可确保外部第三方JAX-WS运行时及其相关库JAR文件在类加载器搜索路径中排在首位。 ，从而确保使用第三方实现代替WebSphere Application Server。

Changing the class loader policy to parent last ensures that the external third-party JAX-WS run time and their dependent library JAR files are first in the class loader search path, thereby ensuring that the third-party implementation is used instead of the WebSphere Application Server.


  • 在管理控制台中，单击应用程序>应用程序类型 > WebSphere企业应用程序> application_na我>类加载和更新检测。

  • 在类重新加载选项下，选择覆盖Web和EJB模块的类重新加载设置。

  • 在类加载器顺序下，将类加载器顺序属性选择为首先使用本地类加载器加载的类（最后是父级）。

  • 单击确定，然后单击保存以保存所做的更改。

  • In the administrative console, click Applications > Application Types > WebSphere enterprise applications > application_name > Class loading and update detection.
  • Under Class reloading options, select Override class reloading settings for Web and EJB modules .
  • Under Class loader order, select Class loader order property to Classes loaded with local class loader first (parent last).
  • Click OK, and then Save to save your changes.

关闭Web服务注释扫描。

Turn off Web services annotation scanning.

注释扫描可以在应用程序级别或在服务器级别。
要在应用程序级别关闭注释扫描，请将WAR文件或EJB模块的META-INF / MANIFEST.MF中的DisableIBMJAXWSEngine属性设置为true。示例：

Annotation scanning can be turned off at the application level or at the server level.To turn off annotation scanning at the application level, set the DisableIBMJAXWSEngine property in the META-INF/MANIFEST.MF of a WAR file or EJB module to true. Example:

Manifest-Version: 1.0
DisableIBMJAXWSEngine: true

要在服务器级别关闭Web服务注释扫描：

To turn off Web services annotation scanning at the server level:


  • 在管理控制台中，转到Java虚拟机的定制属性页面。

  • In the administrative console, go to the Custom properties page for the Java virtual machine.

服务器>服务器类型> WebSphere应用程序服务器> server_name，然后，在服务器基础结构下，单击Java和进程管理>进程定义> Java虚拟机>定制属性

Servers > Server Types > WebSphere application servers > server_name, and then, under Server Infrastructure, click Java and process management > Process definition > Java virtual machine > Custom properties

将com.ibm.websphere.webservices.DisableIBMJAXWSEngine属性设置为true

Set the com.ibm.websphere.webservices.DisableIBMJAXWSEngine property to true

如果该属性对于您的配置尚不存在，请单击新建，然后在名称字段中添加com.ibm.websphere.webservices.DisableIBMJAXWSEngine，然后输入true在值字段中。

If this property does not already exist for your configuration, click New, and add com.ibm.websphere.webservices.DisableIBMJAXWSEngine in the Name field and true in the Value field.

在完成所有这些设置和服务器后重新启动后，异常消失了。在重新部署了该应用程序之后，BUT被废除了。显然，尽管addJCEProviders设置为false，但IBM仍然会加载自己的安全提供程序。在我们的情况下，这是可以接受的状态（需要重新启动WAS服务器才能使其正常工作）

After all these settings and server restart, the exception dissapeared. BUT repeared after some redeployments of the application. Apparently IBM still loads it's own security provider, despite the fact, that the addJCEProviders is set to false. In our case, this is acceptable state (restart of WAS server is needed to make it work)

希望这对某人有所帮助。

Hope this would be helpful for somebody.
