com.ibm.xml.xlxp2.api.stax.XMLOutputFactoryImpl 不兼容
javax.xml.stream.XMLOutputFactory
com.ibm.xml.xlxp2.api.stax.XMLOutputFactoryImpl 不兼容
javax.xml.stream.XMLInputFactory
从 APP(Web-inf/lib) 中删除了具有“XMLOutputFactory”和“XMLInputFactory”类的“jsr173_1.0_api.jar”、“stax-api-1.0-2.jar”，以避免与服务器版本发生任何冲突。
还将战争类加载器顺序更改为“父级最后”并且
WebSphere 管理中的“应用程序的单一类加载器”策略
安慰。进行此更改以优先考虑应用程序 jarWebInf/lib比服务器罐子。
下面是堆栈跟踪。

在解决类加载问题时，您可能需要
覆盖父类加载器可见的类。要覆盖这样的
具有特定于应用程序的类，设置类加载器
在包含应用程序的类加载器上将模式设置为最后一个父级
其类路径上的类。应用程序可以覆盖可见的类
到父类加载器，但这样做可能会导致
ClassCastException 或 UnsatisfiedLinkError 如果混合使用
重写类和非重写类。
您正在使用第三方 JSF 实现。作为第一步，我建议您检查是否配置正确。这是信息中心链接配置 JavaServer Faces 实现 http://pic.dhe.ibm.com/infocenter/wasinfo/v7r0/topic/com.ibm.websphere.nd.multiplatform.doc/info/ae/ae/tweb_jsf.html.
基本上你必须
- 创建一个隔离的共享库
- 将 JSF 库及其依赖项放入其中
- 将共享库与您的模块关联
- 将应用程序类加载器策略设置为 PARENTLAST
