WebSphere Application Server 7.x中的类加载器问题 [英] Classloader issue in WebSphere Application server 7.x
问题描述
com.ibm.xml.xlxp2.api.stax.XMLOutputFactoryImpl与以下版本不兼容 javax.xml.stream.XMLOutputFactory
com.ibm.xml.xlxp2.api.stax.XMLOutputFactoryImpl incompatible with javax.xml.stream.XMLOutputFactory
com.ibm.xml.xlxp2.api.stax.XMLOutputFactoryImpl与以下版本不兼容 javax.xml.stream.XMLInputFactory
com.ibm.xml.xlxp2.api.stax.XMLOutputFactoryImpl incompatible with 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.
Removed "jsr173_1.0_api.jar", "stax-api-1.0-2.jar" that has "XMLOutputFactory" and "XMLInputFactory" classes from APP(Web-inf/lib) to avoid any collision with server versions.
还将战争类装载机的顺序更改为父级最后一个"，并且
WebSphere admin中针对应用程序的单个类加载器"的策略
安慰.进行了此更改，使应用程序jar WebInf/lib的优先级高于服务器jar.
Also changed the war class loader order to "parent last" and
policy to "Single class loader for application" in WebSphere admin
console. Have made this change to give priority to application jars WebInf/lib than server jars.
下面是堆栈跟踪.

When troubleshooting class loading problems, you might need to override classes visible to a parent class loader. To override such classes with those specific to an application, set the Class loader mode to Parent last on the class loader that contains the application classes on its classpath. An application can override classes visible to a parent class loader, but doing so can result in a ClassCastException or UnsatisfiedLinkError if there is a mixed use of overridden classes and non-overridden classes.
推荐答案
您正在使用第三方JSF实现.第一步，我建议您检查是否已正确配置.这是
You are using a third party JSF implementation. As a first step I'd suggest you to check if you have configured it right. Here is the infocenter link for Configuring JavaServer Faces implementation.
基本上您必须
- 创建一个隔离的共享库
- 将您的JSF库及其依赖项放入其中
- 将共享库与您的模块相关联
- 将应用程序类加载器策略设置为PARENTLAST
