Java XOPEncodingStreamWriter与DataHandlerWriter不兼容——WAS8.5.5.2+；公理

有谁能告诉我为什么会出现下面的错误

由于异常（java.lang.ClassCastException:org.apache.axiom.util.stax.xop.XOPEncodingStreamWriter与org.apache.axiom.ext.stax.datahandler.DataHandlerWriter不兼容）而无法执行呈现

我在WAS8.5.5.2中部署的应用程序中使用axiom。同样的应用程序在Jboss6中使用axiom impl、axiom api、axiom ext 1.2.12 jars运行良好，但在Websphere中出现以下错误。没有任何线索

您是否尝试将web模块上的classloader更改为ParentLast？为什么要问两次相同的问题（）？您好，是的，尝试过，但发现了许多问题，而不是此问题。我无法识别websphere或AXIOM的错误。不幸的是，我问了好几次……您好，我发现org.apache.axiom.util.stax.xop.XOPEncodingStreamWriter类根本没有使用，但为什么这个类已经成为我执行的一部分。有没有排除这个类的线索
